Despatcher Training Simulator (DTS) at PSTI, Bangalore
A Despatcher Training Simulator (DTS) is in service at Power Systems Training Institute (PSTI), Bengaluru since March 2011. The Simulated Network comprises of a network of about 1000 stations and 2000 buses with generation voltages of 110 KV and above. The actual network of National Load Despatch Centre as on April 2010 conditions are simulated in the DTS. The databases, displays, events, applications etc. are implemented as per state-of-the-art Load Despatch Control Software. The Simulator is providing a complete full-scope and real-time accurate simulation of Grid Systems, Processes, Control and Instrumentation, Grid Operations etc., for the Indian National Grid. IEEE representation in one-line diagram has been adopted.
The Simulator is being utilized for imparting training in Power System Operation and allied areas. The Despatcher Training Simulator (DTS) provides realistic environment for the System Operators to practice operating tasks under both normal and emergency conditions. The DTS responds in a real-time operating mode replicating the actual power system operation. The Man-machine interface (MMI) used in the DTS is much identical to those used in system control centres. It raises the level of proficiency and builds up the confidence required to handle emergencies in an actual system operation. It is a comprehensive tool for training of Power System and Load Despatch Engineers and Despatchers.
- The Simulator can be used to train the engineers in the following aspects of Power System Operation
- Control of active power flow to maintain transmission levels within permissible Operating limits by taking appropriate measures (generation control and load management).
- Control of reactive power flow and voltage by adjustments of Automatic Voltage Regulator (AVR) set points, transformer taps and switching on/off shunt reactive elements.
- Training in dynamic behaviour of power system between steady states including response of different power plants to frequency fluctuations, automatic generation control signals and effects of power plant operator actions.
- Training in recognition of critical system conditions such as insufficient generation reserve, insufficient reactive support, transmission line overloading etc.
- The despatcher can practice use of the load frequency control and economic despatch functions for following the system load. The trainee can have exercises on units’ ON and OFF control, adjusting regulating limits in co-ordination with power plant operators.
- Through the SCADA displays, the despatcher can open and close circuit breakers for removal or reconnection of Power System elements. He can coordinate with the sub-station operators.
- The despatcher can practice procedures for restarting a power system from black start, re-energizing transmission lines, loads and re-synchronizing islands.
