Study on the Calculation Method of ω Input Signal in
PSS4B Model

Abstract

Abstract: A study on the calculation method of speed input signal in PSS4B model is proposed. The method has less computation and is easy to realize in the excitation regulator. It provides a simple and effective way to implement PSS4B on the generator excitation regulator. Through the RTDS platform to build the model test, the effect of PSS4B on low frequency oscillation in three bands of high, medium and low frequency are compared. The results show that the PSS4B of speed input signal of the algorithm has obvious inhibition effect on the oscillation of each frequency band.

Key words: Power system stabilizer, speed, low frequency oscillation

摘要： 一种电力系统稳定器（Power System Stabilizer, PSS）PSS4B模型中转速ω的计算方法，其实现过程计算量较少，在励磁调节器上实现灵活方便，为在发电机励磁调节器上实现PSS4B提供了一种较为简单有效的途径。通过在RTDS平台搭建模型进行试验，分别对比PSS4B对高、中、低三个频段低频振荡的抑制效果，结果表明以本算法求出的ω为输入信号的PSS4B对各频段振荡均有明显的抑制效果。
