DPL

Chapter1

DPL

The DIgSILENT Programming Language “DPL” serves the purpose of offering an interface for automating tasks in the PowerFactory program. The DPL method distinguishes itself from the command batch method in several aspects: • DPL offers program decision and flow commands • DPL offers the definition and use of user-defined variables • DPL has a flexible interface for input-data and external objects • DPL offers mathematical expressions The DPL adds a new dimension to the DIgSILENT PowerFactory program by allowing the creation of new calculation functions. Such user-defined calculation commands can be used in all areas of power system analysis, such as • Network optimizing • Cable-sizing • Protection coordination • Stability analysis • Parametric sweep analysis • Contingency analysis • etc. etc. Such new calculation functions are written as program scripts which comprise • flow commands like ‘if-then-else and ‘do-while’ • DIgSILENT commands (i.e. load flow or short-circuit commands) • Input and output routines • Mathematical expressions • DIgSILENT object procedure calls • subroutine calls Such program scripts are executed by DPL command objects. To understand the DPL philosophy and the resulting hierarchical structure of DPL scripts, the following is important to understand:

DPL

• A DPL command either executes its own script or the script of another, remote, DPL command. In the first case, the DPL command is called a ‘root command’ and the script is called a ‘local script’. In the second case, the DPL command is called a ‘referring’ command and the script is called a ’remote script’. • A root command may define interface variables that are accessible from outside the script and which are used to define default values. • Each root command may define one or more external objects. External object are used to make a DPL command run with specific power system objects, selections, commands, etc. • A referring command may overrule all default interface values and all selected external objects of the remote command. • Each DPL command can be called as a subroutine by other DPL commands. The use of remote scripts, external objects and interface variables makes it possible to create generic DPL commands, which may be used with different settings in many different projects and study cases.

1.1 The DPL Command Object The DPL command object holds a reference to a remote DPL command when it is not a root command. The example depicted in Fig. 1.1 is apparently a referring command, since its “DPL script” reference is set to the remote command \L IBRARY\DPL C OMMANDS\C HECK VL OADING. A root command has its own script on the “script” page of the dialog. A referring command uses the script of the remote DPL command. The DPL command also holds a reference to a selection of objects (“General Selection”). The general selection in the example is empty. Only one single “General Selection” is valid at a time for all DPL scripts. This means that setting the “General Selection” in one DPL command dialog, will change the “General Selection” for all DPL commands in the database. The interface section is used to define variables that are accessible from outside the DPL command itself. DPL commands that call other DPL commands as subroutines, may use and change the values of the interface variables of these DPL subroutines. The list of External Objects is used to execute the DPL command for specific objects. A DPL command that, for example, searches the set of lines for which a short-circuit causes too deep a voltage dip at a specific busbar, would access that specific busbar as an external object. Performing the same command for another busbar would then only require setting the external object to the other busbar. The most important part of a DPL root command is of course the actual DPL program script. That script is written on the “Script” page of a DPL root command dialog.

1.2 The DPL Script Language The DPL script language uses a syntax quite similar to the C++ programming language. This type of language is intuitive, easy to read, and easy to learn. The basic command set has been kept as small as possible.

Figure 1.1: A DPL command

The syntax can be divided into the following parts: • variable definitions • assignments and expressions • program flow instructions • method calls The statements in a DPL script are separated by semicolons. Statements are grouped together by braces. Example: statement1; statement2; if (condition) { groupstatement1; groupstatement2; }

1.2.1 Variable Definitions DPL uses the following internal parameter types • double, a 15 digits real number • int, a integer number

DPL Manual

DPL

• string, a string • object, a reference to a DIgSILENT object • set, a container of objects Vectors and Matrices are available as external objects. The syntax for defining variables is as follows: [VARDEF] [TYPE]

= =

[TYPE] varname, varname, ..., varname; double | int | object | set

All parameter declarations must be given together in the top first lines of the DPL script. The semicolon is obligatory. Examples: double int string object set

Losses, Length, Pgen; NrOfBreakers, i, j; txt1, nm1, nm2; O1, O2, BestSwitchToOpen; AllSwitches, AllBars;

1.2.2 Assignments and Expressions The following syntax is used to assign a value to a variable: variable variable variable

= += -=

expression expression expression

The add-assignment “+=” adds the right side value to the variable and the subtract-assignment “-=” subtracts the right-side value. Examples: double x,y; x = 0.5*pi(); y = sin(x); x += y; y -= x;

! ! ! !

x y x y

now now now now

equals equals equals equals

1.5708 1.0 2.5708 -1.5708

The following operators and functions are available: • arithmetic operators: +, -, *, / • standard functions: sin(x) cos(x) acos(x) atan(x) tanh(x) exp(x) abs(x) min(x,y) trunc(x) frac(x) pow(x,y) modulo(x,y) rand()

tan(x) sinh(x) ln(x) max(x,y) round(x) ceil(x)

asin(x) cosh(x) log(x) (basis 10) sqrt(x) (square root) sqr(x) (power of 2) floor(x)

All trigonometric functions are based on radians (RAD). The function ‘rand()’ returns a uniform distributed random number in the range [0, 1].

1.2.3 Program Flow Instructions The following flow commands are available. if if do while

( [boolexpr] ) ( [boolexpr] ) [statlist] ( [boolexpr] )

[statlist] [statlist] while [statlist]

else ( [boolexpr] )

[statlist]

in which [boolexpr] [boolcomp] [statlist]

= = =

expression [boolcomp] expression ”<” | ”>” | ”=” | ”>=” | ”>=” | ”<>” statement; | { statement; [statlist] }

• Unary operators: ”.not.” • Binary operators: ”.and.” | ”.or.” | ”.nand.” | ”.nor.” | ”.eor.” • Parentheses: {logical expression} Examples: if (a<3) b = a*2; else b = a/2; while (sin(a)>=b*c) { a = O:dline; c = c + delta; } if ({.not.a}.and.{b<>3}) { err = Ldf.Execute(); if (err) { Ldf:iopt_lev = 1; err = Ldf.Execute(); Ldf:iopt_lev = 0; } }

Break and Continue The loop statements ‘do-while’ and ‘while-do’ may contain ‘break’ and ‘continue’ commands. The ‘break’ and ‘continue’ commands may not appear outside a loop statement. The ‘break’ command terminates the smallest enclosing ‘do-while’ or ‘while-do’ statement. The execution of the DPL script will continue with the first command following the loop statement. The ‘continue’ command skips the execution of the following statements in the smallest enclosing ‘do-while’ or ’while-do’ statement. The execution of the DPL script is continued with the evaluation of the boolean expression of the loop statement. The loop statement list will be executed again when the expression evaluates to TRUE. Otherwise the loop statement is ended and the execution will continue with the first command following the loop statement. Examples:

DPL Manual

DPL

O1 = S1.First(); while (O1) { O1.Open(); err = Ldf.Execute(); if (err) { ! skip this one O1 = S1.Next; continue; } O2 = S2.First(); AllOk = 1; DoReport(0); !reset while (O2) { err = Ldf.Execute(); if (err) { ! do not continue AllOk = 0; break; } else { DoReport(1); ! add } O2 = S2.Next(); } if (AllOk) { DoReport(2); ! report } O1 = S1.Next(); }

1.2.4 Input and Output The “input” command asks the user to enter a value. input(var, string); The input command will pop up a window with the string and a input line on which the user may enter a value. The value will be assigned to the variable “var”. The “output” command writes a line of text to the output window. output(string); The string may contain “=”-signs, followed by a variable name. The variable name will then be replaced by the variable’s value. Example: input(diameter, ’enter diameter’); output(’the entered value=diameter’); The example results in the pop up of a window as depicted inFig. 1.2. The following text will appear in the output window: DIgSI/dpl - the entered value=12.3400

DPL

Figure 1.2: The input window The output command is considered obsolete and has been replaced by the more versatile “printf” and “sprintf” functions. See “sprintf” in 1.8.3, page 21 and “printf” in 1.8.3, page 21 for more information.

1.3 Access to Other Objects With the syntax for the parameter definitions, program flow and the input and output, it is already possible to create a small program. However, such a script would not be able to use or manipulate variables of ‘external’ objects. It would not be possible, for instance, to write a script that replaces a specific line by possibly better alternatives, in order to select the best line type. Such a script must be able to access specific objects (the specific line) and specific sets of objects (the set of alternative line types). The DPL language has several methods with which the database objects and their parameters become available in the DPL script: • The most direct method is to create an object, or a reference to an object, in the DPL command folder itself. Such an object is directly available as “object” variable in the script. The variable name is the name of the object in the database. • The general selection may be used. This method is only useful when the order in which the objects are accessed is not important. The general selection is automatically filled when a selection is right clicked in either the single line graphic or the database browser and the option “Execute DPL script” is selected. • The list of external objects is mainly used when a script should be executed for specific objects or selections. The list of external objects is nothing more than a list of ‘aliases’. The external object list is used to select specific objects for each alias, prior to the execution of the script.

1.3.1 Object Variables and Methods If a database object is known to the DPL command, then all its methods may be called, and all its variables are available. For example, if we want to change a load flow command in order to force an asymmetrical load flow calculation, we may alter the parameter “iopt net”. This is done by using an assignment: Ldf:iopt_net = 1; ! force unbalanced In this example, the loadflow objects is known as the objects variable “Ldf”. The general syntax for a parameter of a database object is

DPL Manual

DPL

objectname:parametername In the same way, it is possible to get a value from a database object, for instance a result from the load flow calculations. One of such a result is the loading of a line object, which is stored in the variable “c:loading”. The following example performs the unbalanced loadflow and reports the line loading: 00. 01. 02. 03. 04. 05. 06. 07. 08. 09.

int error; double loading; Ldf:iopt_net = 1; ! force unbalanced error = Ldf.Execute(); ! execute load flow if (error) { exit(); } else { loading = Line:c:loading; ! get line loading output(’loading=loading’); ! report line loading }

This examples is very primitive but it shows the basic methods for accessing database objects and their parameters.

1.4 Access to Locally Stored Objects The access to locally stored (references to) objects is only possible if the name of the object qualifies as a variable name in the DPL script. It will not be possible to access an object which name is “My Loadflow\~{}1*”, for instance. An example is shown in Fig. 1.3, where a DPL script is shown on the left which has a load flow command and a reference to a line in its contents folder on the right.

Figure 1.3: DPL contents The example DPL script may now access these objects directly, as the objects “Ldf” and “Line”. In the following example, the object “Ldf”, which is a load flow command, is used in line 01 to perform a load flow. 00. 01. 02. 03. 04. 05.

int error; error = Ldf.Execute(); if (error) { output(’Load flow command returns an error’); exit(); }

In line 01, a load flow is calculated by calling the method “Execute()” of the loadflow command. The details of the loadflow command, such as the choice between a balanced single phase or an

DPL Manual

DPL

unbalanced three phase load flow calculation, is made by editing the object “Ldf” in the database. Many other objects in the database have methods which can be called from a DPL script. The DPL contents are also used to include DPL scripts into other scripts and thus to create DPL “subroutines”.

1.5 Accessing the General Selection Accessing database objects by storing them or a reference to them in the DPL command would create a problem if many objects have to be accessed, for instance if we want to search the line with the highest loading. It would be impractical to create a reference to each and every line. A more elegant way would be to use the DPL global selection and fill it with all lines. The database browser offers several ways in which to fill the DPL selection with little effort. The selection may then be used to access each line indirectly by a DPL “object” variable. In this way, we may create a loop in which we search for the highest loading. This is shown in the following example. 00. 01. 02. 03. 04. 05. 06. 07. 08. 09. 10. 11. 12. 13. 14. 15. 16. 17. 18. 19. 20. 21. 22. 23. 24. 25.

int error; double max; object O, Omax; set S; error = Ldf.Execute(); if (error) exit();

! execute a loadflow ! exit on error

S = SEL.AllLines(); ! Omax = S.First(); ! if (Omax) { max = Omax:c:loading; ! } else { output(’No lines found in exit(); ! } O = S.Next(); ! while (O) { ! if (O:c:loading>max) { max = O:c:loading; ! Omax = O; ! } O = S.Next(); } output(’max loading=max for Omax.ShowFullName();

get all selected lines get first line initialize maximum selection’); no lines: exit get next line while more lines update maximum update max loaded line

line’); !output results

The object “SEL” used in line 08 is the reserved object variable which equals the “General Selection” in the DPL command dialog. The “SEL” object is available in all DPL scripts at all times and only one single “General Selection” object is valid at a time for all DPL scripts. This means that setting the “General Selection” in the one DPL command dialog, will change it for all other DPL commands too. The method “AllLines()” in line 08 will return a set of all lines found in the general selection. This set is assigned to the variable “S”. The lines are now accessed one by one by using the set methods “First()” and “Next()” in line 09, 16 and 22. The line with the highest loading is kept in the variable “Omax”. The name and database location of this line is written to the output window at the end of the script by calling “ShowFullName()”.

DPL

1.6 Accessing External Objects The DPL contents makes it possible to access external object in the DPL script. The special general selection object (“SEL”) is used to give all DPL functions and their subroutines access to a central selection of objects. Although flexible, this method would create problems if more than one specific object should be accessed in the script. By creating references to those objects in the DPL command itself, the DPL command would become specific to the current calculation case. Gathering the objects in the general selection would create the problem of selecting the correct object. To prevent the creation of calculation-specific DPL commands, it is recommended practice to reserve the DPL contents for all objects that really ‘belong’ to the DPL script and which are thus independent on were and how the script is used. Good examples are load flow and short-circuit commands, or the vector and matrix objects that the DPL command uses for its computations. If a DPL script must access a database object dependent on where and how the DPL script is used, an “External Object” must be added to the external object list in the DPL root command. Such an external object is a named reference to a external database object. The external object is referred to by that name. Changing the object is then a matter of selecting another object. In Fig. 1.4, an example of a external object is given. This external object may be referred to in the DPL script by the name “Bar1”, as is shown in the example.

Figure 1.4: DPL external object table Example: sagdepth = Bar1:u;

1.7 Remote Scripts and DPL command Libraries The easiest way to develop a new DPL command is to create a new ComDpl in the currently active study case and to write the script directly in that DPL object. In such a way, a DPL “root command” is made. If this root command needs DPL subroutines, then one or more DPL command objects may be created in its contents. Each of these subroutines will normally also be written as root functions. The newly written DPL command with its subroutines may be tested and used in the currently active study case. However, it cannot be executed when another study case is active. In order to use the DPL command in other study cases, or even in other projects, we would have to copy the

DPL Manual

11


DPL

DPL command and its contents. This, however, would make it impossible to alter the DPL command without having to alter all its copies. The solution is in the use of ‘remote scripts’. The procedure to create and use remote scripts is described as follows. Suppose we have created and tested a new DPL command in the currently active study case. We would like to store this DPL command in a save place and make it possible to use it in other study cases and projects. This is done by the following steps: • copy the DPL command to a library folder. This will also copy the contents of the DPL command, i.e. with all it’s DPL subroutines and other locally stored objects. • “Generalize” the copied DPL command by resetting all project specific external objects. Set all interface variable values to their default values. To avoid deleting a part of the DPL command, make sure that if any of the DPL (sub)commands refers to a remote script, all those remote scripts are also stored in the library folder. • Activate another study case. • Create a new DPL command object (ComDPL) in the active study case. • Set the “DPL script” reference to the copied DPL command. • Select the required external objects. • Optionally change the default values of the interface variables • Press the Check button to check the DPL script The Check or Execute button will copy all parts of the remote script in the library that are needed for execution. This includes all subroutines, which will also refer to remote scripts, all command objects, and all other objects. Some classes objects are copied as reference, other classes are copied completely. The new DPL command does not contain a script, but executes the remote script. For the execution itself, this does not make a change. However, more than one DPL command may now refer to the same remote script. Changing the remote script, or any of its local objects or sub-commands, will now change the execution of all DPL commands that refer to it.

1.7.1 Subroutines and Calling Conventions A DPL command object may be included in the contents of another DPL command. In that case, the included DPL “subroutine” may be called in the script of the enclosing DPL command. In principle, this is not different from calling, for example, a load flow command from a DPL script. As with most other command objects, the DPL command only has one method: int Execute() ; executes the DPL script. The difference is that each DPL subroutine has different interface parameters, which may be changed by the calling command. These interface parameters can also be set directly at calling time, by providing one or more calling arguments. These calling arguments are assigned to the interface parameters in order of appearance. The following example illustrates this. Suppose we have a DPL sub-command “Sub1” with the interface section as depicted in Fig. 1.5. The calling command may then use, for example:

DPL Manual

12


DPL

Figure 1.5: Interface section of subroutine ! set the parameters: Sub1:step = 5.0; Sub1:Line = MyLine; Sub1:Outages = MySelection; ! execute the subroutine: error = Sub1.Execute(); However, using calling arguments, we may also write: ! execute the subroutine: error = Sub1.Execute(5.0, MyLine,

MySelection);

1.8 DPL Functions and Subroutines The DPL syntax is very small because it mainly serves the purpose of basic operations like simple calculations, if-them-else selections, do-while’ loops, etc.. The strength of the DPL language is the possibility to call functions and to create subroutines. A function which can be called by a DPL command is called a “method” . Four types of methods are distinguished: Internal methods These are the build-in methods of the DPL command. They can be called always. Set methods These methods are available for the DPL ‘set’ variables. Object methods These methods are available for the DPL ‘object’ variables. External methods These are the methods which are available for certain external DIgSILENT objects, such as the loadflow command, the line object, the asynchronous machine, etc.

1.8.2 DPL Set Methods Set methods are functions for the set type parameters. set . [SETMETHOD] ( arguments ) ; The following [SETMETHOD] methods are available: Clear IsIn Add Remove Count First Next Firstmatch Nextmatch FirstFilt NextFilt SortToVar SortToClass SortToName MarkInGraphics

1.8.3 Object Methods The object methods are specific for each type of object class. A result file object (ElmRes), for instance, has a “Write” method, which would not make sense for a load flow command object. The general syntax for an object method equals that of the set method: object . [OBJMETHOD] ( arguments ) ;

Format String Syntax The string printing commands “printf” , “sprintf” , “Error” , “Warn” , and “Info” all use the same format string syntax. The format string must contain a valid place holder for every given argument. The placeholder format is [flags] [width] [.precision] type Where “type” is one of the following specifiers: ’d’ or ’i’ For an integer value. ’e’ For a double value. The printed format is “[ ]d.dddd e [sign]ddd” where d is a single decimal digit, “‘dddd” is one or more decimal digits, “ddd” is exactly three decimal digits, and “[sign]” is “+” or “”. ’E’ Identical to the e format except that “E” in stead of “e” is used. ’f’ For a double value. Printed format is “[ ]dddd.dddd”, where “dddd” is one or more decimal digits. The number of digits before the decimal point depends on the magnitude of the number, and the number of digits after the decimal point depends on the requested precision. ’g’ For a double value. Printed format is the “f” or “e” format, whichever is more compact for the given value and precision. The e format is used only when the exponent of the value is less than 4 or greater than or equal to the precision argument. Trailing zeros are truncated, and the decimal point appears only if one or more digits follow it. ’G’ Identical to the “g” format, except that “E” in stead of “e”, is used (where appropriate). ’s’ For a string. The optional “flag” can be one of the following specifiers: ’-’ : Left align the result within the given field width.

Write int Write (string Format, [object aObj | set aSet], ...) Writes out a line of formatted text, using the DIgSILENT output language. Arguments string Format (obligatory) : The format string object aObj (optional) : An object which is used to get data from set aSet (optional) : A set which is used to get objects from Return value 0 on success, 1 on error The “Write” command is used to quickly output a line of formatted output, using the same formatting language as is used for defining reports and result-boxes. See “The DIgSILENT output language” in ??, page ?? for more information. Because data or parameters of more than object is often written out, the DIgSILENT output language has the special macro “ACC(x)” to distinguish between these objects. Prior to execution, all given objects and all objects in the given sets are listed together in a single list. The “ACC(x)” macro returns the object with the index “x” in that list. The ACC (“acc”=“access”) macro can be used more than once for the same object. Interface variables of the DPL script can also be used in the format string by the “DEF” macro. If the DPL script has “ResX” as an interface double, then “DEF:ResX” will access that variable. Example In the following example, two lines of output are written out. The first line only contains normal text. The second line writes the name and loading of two lines. In this example, “ACC(1)” refers to the object “LineA’, and “ACC(2)” to “LineB” Write(’The following results are found’); Write(’# : #.## # , # : #.## # $N, ACC(1):loc_name,ACC(1):c:loading,[ACC(1):c:loading, ACC(2):loc_name,ACC(2):c:loading,[ACC(2):c:loading’, LineA, LineB); Also see “printf” in 1.8.3, page 21 .

WriteOut int IntForm.WriteOut (Set ListSet, Set PoolSet) Write the report to the output window. The report form object will write a report to the output window, based on the format text, for the objects in the ListSet and the PoolSet. The ListSet is used in the _EXTERNAL macro. All format lines between the $LOOP,_EXTERNAL and the $END macro’s will be written for each object in the Listset, which is therefore called the ‘sequential set’. In the format text itself, objects from the PoolSet may be referenced directly by the “ACC(x)” macro, which is replaced by the x’th object in the PoolSet. The PoolSet is therefore called the ‘random access set’. The ListSet or PoolSet may be empty. The command object that is normally reached by the macro “DEF” in report forms will always return the main DPL command that is running at the moment, even when the ‘WriteOut’ call is made in a DPL subscript.

void IntPlot.SetScaleX (double min, double max, int log) Sets scale of y-axis. Invalid arguments like negative limits for logarithmic scale are not set. No arguments =¿ automatic scaling. Arguments double min (optional) : Minimum of y-scale. double max (optional) : Maximum of y-scale. int log (optional) : ¿ 0 =¿ y-scale is logarithmic; 0 =¿ y-scale is linear. Return value none Example The following example looks for a Subplot named ’RST’ and set its y-axis scale. There are three different examples. 1. Example: Perform auto scaling on y-Axis. 2. Example: Set minimum to 0 and maximum to 20. 3. Example: Set minimum to 1 and maximum to 1000. Changes to a log. scale !
