Performance Test of Generator Terminal Supplement Damping Control Based on Real-Time Digital Simulation

Generator terminal supplement damping control (GTSDC) is an effective method to damp the sub-synchronous resonance. In this paper, the real time closed loop testing technique of GTSDC is studied. The four kind of performance test is discussed. They are characteristic valuation of GTSDC, model contrast of GTSDC and real-time digital simulation (RTDS), GTSDC coordination with the excitation damping control, and robustness analysis of GTSDC. The testing results show that the real time closed loop testing technique of GTSDC is effective and reliable.
