General Principles of Substation Automation The general principles of the substation operation have not changed, since their developing days. Therefore the control and protection tasks remain the same.

The objective of modern substation automation (SA) is to solve these tasks in a more efficient and economical way by using state of the art information technologies (IT) and to provide more functionality to work plant and systems harder.

This system is adopted for New Substations, at the time of tendering. This is Distributed IEDs for each Switch Yard Equipment for Operation and Maintenance.This is Called Process Bus Automation. Non Conventional Instrument Transformers for Voltage and Current Measurement . In this Distributed Control Rooms / Bay Kiosks / Portable relay Rooms are not required. One complete Panel for one Bay. All control, Protection IEDs TVM/EM are available. No Physical wiring from Switch Yard to Bay to Control. Total Fibre Optic Ethernet connection and IEC61850 Communication. No Cable Trenches. No DC Leakage. But Centralised Auxiliary System and Physical Cabling to all Bay switch yard equipment and relays and other accessory systems. Switch yard is fixing with no of Digital Cameras and focusing the major equipment to View the yard and this is having a facility to Move in slow motion, around the bay to cover all the Major equipments. This also put in Network to Monitor from remote/ Local. The Numerical IEDs , Energy Meters, MFM and Digital Cameras are connected in Network in Ethernet Switch and to Station Control System and connected through Gateway to Remote Control Center and ALDC / SLDC / RLDC / NLDC. The Operator, those who are sitting at Remote control Center having a System and he can Monitor the substation and take a decision for any thing. This is Stage-4 Substation Control System called Process Bus Substation Automation System. Civil Engineering Cost in the yard reduces Drastically. The Main Control Room Having only Network system with Printer and Aux System Monitoring. But still Auxiliary system Location is Centralised, but Not Distributed. This concept is not changing. Redundant, alternative communication channels are required to safe guard if FO cable damages. The reliability of system Depends on availability of Fibre Optic System.

SUBSTATION AUTOMATION SYSTEM (Stage-5 Development) PROCESS LEVEL INTELLIGENT SUBSTATION AUTOMATION WITH GSM / CDMA NETWORK PREPARED BY GOPALA KRISHNA PALEPU ADE/400KV/ VS/HYD [email protected], Mobile:9440336984

This system is adopted for New Substations, at the time of tendering. This is Distributed IEDs for each Switch Yard Equipment for Operation and Maintenance. This is Called Process Bus Automation. Non Conventional Instrument Transformers for Voltage and Current Measurement . In this Distributed Control Rooms / Bay Kiosks / Portable relay Rooms are not required. One complete Panel for one Bay. All control, Protection IEDs TVM/EM are available. No Physical wiring from Switch Yard to Bay to Control. Total GSM/CDMA connection and IEC61850 Communication. But Centralised Auxiliary System and Physical Cabling to all Bay switch yard equipment and relays and other accessory systems. Switch yard is fixing with no of Digital Cameras and focusing the major equipment to View the yard and this is having a facility to Move in slow motion, around the bay to cover all the Major equipments. This also put in Network to Monitor from remote/ Local. The Numerical IEDs , Energy Meters, MFM and Digital Cameras are connected in Network in Ethernet Switch and to Station Control System and connected through Gateway to Remote Control Center and ALDC / SLDC / RLDC / NLDC. The Operator, those who are sitting at Remote control Center having a System and he can Monitor the substation and take a decision for any thing. This is Stage-5 Substation Control System called Process Bus Substation Automation System. Civil Engineering Cost in the yard reduces Drastically. The Main Control Room Having only Network system with Printer and Aux System Monitoring. But still Auxiliary system Location is Centralised, but Not Distributed. This concept is not changing. Redundant, alternative communication channels are required with GSM / CDMA. The reliability of system Depends on availability of GSM / CDMA.

BAY LEVEL SUBSTATION AUTOMATION ¾ DECENTRALIZED ARCHITECTURE DISTRIBUTED CONTROL ROOMS USING BAY KIOSKS CALLED PORTABLE RELAY ROOMS. ¾ BAY-ORIENTED CONCEPT – EACH BAY PROVIDED WITH BAY KIOSKS/ PORTABLE RELAY ROOMS. ¾ DISTRIBUTED INTELLIGENCE – EACH BAY PROVIDED WITH CONTROL IEDs (BCUs) FOR CONTROL & MONITORING FUNCTIONS. EACH BAY PROVIDED WITH PROTECTION IEDs (BPUs) FOR PROTECTION. ¾ DECENTRALIZED FUNCTIONS. ¾ USING IEC 61850 (UNIVERSAL) SUBSTATION AUTOMATION PROTOCOL. ¾ IT IS CALLED BAY LEVEL SUBSTATION AUTOMATION.
