GENERATOR UNIT FOR POWER SYSTEM SIMULATION

摘要

PURPOSE:To establish synchronism pull-in conditions in early stage by controlling the inner voltage of a generator unit according to the voltage difference and the frequency difference between the generator side and the system side. CONSTITUTION:A control unit CU is provided with signals from a potential transformer PTS arranged on the system S side wiring and a potential transformer PTG arranged on the generator unit G side wiring. When the voltage difference between the generator side and the system side is lower than a predetermined value, a command is provided to the generator unit G based on a command fed from an operating end Ta while simultaneously a throw-in command is provided to a circuit breaker CB. When the voltage difference exceeds the predetermined value, phase difference between the generator side and the system side is calculated and transmitted to the generator unit G thus performing synchronization control.
