摘　　要：介绍了一种利用转子位置检测器和发电机功角转速测量装置监视发电机稳定性 ,同时配以调速侧电力系统稳定器 ( GPSS)提高发电机静态稳定性的原理及实现方法。单相接地动模实验结果表明 :功角稳定判据显示直观 ;采用 GPSS缩短了发电机恢复稳定的时间 ,提高了发电机的静态稳定性。该方法为实施发电机及电网稳定性的监视和控制提供了一种可行方案。implementation of the method for improving and monitoring generator stability and its principle are introduced.The staIJllity is monitored and improved by using rotor position detector, power angle and rotational speed measuring device.and adopting GPSS. The results of dynamic simulating test on single--phase earth fault show that the power angle for judgingstablllt}' Is displayed directly. the time for restoring generator stability is reduced. and the generator stability is improved byadopting (jPSS. The method provides a feasible scheme to be used in real power system for monitoring and improvinggenerator stability.
