Plant-labeling system The power plant labeling system (PPS) is a plant identification system for uniform and systematic identification of power plants . It has been used since the early 1980s, farmers and power plant power plant operators the unique name and identification of all components of a power plant. The power plant marking system from VGB - Working Group plant identification and documentation maintained and further developed. Be regulated, the PPS indicator in the Directive VGB B105 and B106.

Structure [ Edit ] The labels referred to PPS consists of a 15 - to 17-digit letters - and numbers combination. The letters are generally to classification of the systems and assemblies used. The numbers are usually the count. The PPS distinguishes three types of signs:
Procedural identification , encryption, plant and equipment in the power plant process
Position marking , to encrypt locations and slots in electrical systems
1|Page
Space identification , encryption, the topographic location of facilities and equipment in buildings
The identification of PPS follows a fixed structure , which is to outline steps oriented. It increases from left to right of detail of the plate. The structure of the outline levels is a lpha- n umerisch. In the following, A for letters and N used for numbers. Between the levels of each organization a space is set. When the installation is marking the division between stage 1 and 2 outline the character " . " (Dot) is set.

Outline level 0 - Total plant [ Edit ] The first stage refers to the overall system structure and has counted character. It consists of a number or a letter.
Outline Level 1 - Functional overall system [ Edit ] The second outline level refers to a functional system as a whole in the overall system. It consists of 3 letters and 2 digits with an optional leading digit. The letters are assigned according to a predetermined key systems in power plants. Here, the first letter indicates (from left) are the main systems (so-called main groups ), then the following letters denote the further breakdown into sub-groups. The following two paragraphs have character and be counted as F Ndenotes count.
Outline level 2 - unit [ Edit ] The third stage refers to a structure unit in the subgroup. It consists of two letters and three digits. The letters are assigned according to a predetermined key items (for example, a measurement) in power plants. Here, the first letter refers to a group of units, and the subsequent letter then referred to the further breakdown into subgroups. The following numbers have counted character. Many companies and equipment manufacturers use here a further characterization, in the first numerical number is a functional addition. This means AA3NN that it is a vent, a draining and AA4NN AA6NN a measuring point.
Outline Level 3 - Equipment / signal indicator [ Edit ] The fourth stage structure called a resource or signal indicator in the aggregate. It consists of 2 letters and 2 numbers. The letters are according to a predetermined key operation means (for example, a drive)

assigned. Here, the first letter refers to a group of units, and the subsequent letter then referred to the further breakdown into sub-groups. The following numbers have counted character. If the signal indicator there is a defined assignment, eg XB01 is the "up" acknowledgment from a drive. XB51 is the "Not In" acknowledgment of the same drive, XB02 the "CLOSED" feedback and consequently XB52 the "non CLOSED" feedback.
Example [ Edit ] In a flowsheet is the name: 1 2LAC03 CT002 QT12 Outline level 0: The block 1 of a power plant site receives in this first stage, the labeling Outline Level 1: For the 3rd feed water pump in the second water - steam cycle labeling is 2LAC03. This means:
Main group 2L: 2 Steam, water, gas circuit
Subgroup (2L) A: feedwater system
Subgroup (2LA) C feed water pump system
Counter (2LAC) 03: third feedwater pump system
Outline Level 2: For the second Temperature measurement is the identification CT002. This means:
Main Group C: Direct measurement
Subgroup (C) T: temperature measurement
Counter (CT) 002: second temperature measurement
Outline Level 3: For the 12th Sensor well as sensing devices shall protect the labeling QT12. This means:
Main group Q: Instrumentation and control equipment
Subgroup (Q) T: Protection tubes and thermowells as transducer protection
Counter (QT) 12: Twelfth protective tube or thermowell
With the example above, the 12 Thermowell at the 2nd Temperature measurement at the 3rd Feed pump in block 1 denotes a power plant site.
