Real-time power system simulation for automatic generation control

A digital simulation program used for the design of improved automatic generation control algorithms is described. The program can also be used for study of long-term system dynamics following large load or generation changes. Since the simulation runs faster than real-time, the program, can be used as a real-time power system simulator for control system checkout and operator training. The simulation represents the major Pacific Northwest powerplants plus equivalents for the interconnected power system. Included is a newly developed Kaplan hydro turbine model. Automatic generation Control models include non-linear digital filtering and recently developed digital powerplant controllers.For stochastic load changes, close statistical comparison was obtained between simulation and actual system records.
