Abstract

The invention discloses a closed-loop testing system and a closed-loop testing method for an excitation and packet switching system (PSS) control device of a synchronous generator. The closed-loop testing system comprises a real-time simulation work station, a real time digital system (RTDS), an analog output board card, a power amplifier, an excitation and PSS control device and a digital output board card, wherein the real-time simulation work station is connected with the RTDS; the RTDS transmits current and voltage signals to the excitation and PSS control device through the analog output board card and the power amplifier; the RTDS transmits a grid-connected circuit breaker switching signal of the synchronous generator to the excitation and PSS control device through the digital output board card; and the excitation and PSS control device transmits a pulse trigger signal of a six-pulse rectifier bridge to the RTDS through the digital output board card. The self-parallel excitation closed-loop testing system for the excitation and PSS control device of the synchronous generator is flexible in testing and can perform multiple types of tests.
