摘要
本文应用描述函数法对调速器间隙死区给GPSS造成的影响进行了分析,给出了数字仿真和动模试验结果。理论分析和试验结果均表明间隙的存在不影响GPSS在极限环外抑制电力系统低频振荡的能力,而极限环从理论上估计是不大的,由其产生的振荡幅度在实践中也是可以接受的。
Describing function method based the effect of backlach on governor power system stabilizer(GPSS) is studied in detail. Simulations and physical model tests are shown at last. It is proved that back lash does not affect GPSS' capability to reduce low frequency oscillations. The limit-cycle swing is limitted in. theory and acceptable in application.
