| 摘 要： | 介绍了MEC5220型励磁调节器的原理及系统产生低频振荡的原因，分析了励磁调节器的阻尼特性。通过对有功型电力系统稳定器（PSS）的研究发现，PSS虽能抑制振荡，但有功型PSS使用的前提是机械功率变化相对电气功率变化近似不变，当调节发电机原动机出力时， PSS得到的信号远大于需要的信号，就会造成励磁电压和无功功率大幅变化，即反调。通过实例证实了有功型PSS反调特性，并提出了防止其危害的对策。

| Abstract: | This paper introduces the principle of MEC5220-type exciter regulator,elaborates the reasons of producing low-frequency oscillation in system,and describes the damping characteristics of excitation regulator. By studying the active-type power system stabilizer (PSS),it finds that although PSS can inhibit the oscillations,the merit-based PSS is used on the premise that mechanical power changes much slower than the electrical power changes. When the adjustment is made in generating the original motivation,sig... |
