摘要

安装电力系统稳定器是增强电网小干扰稳定性的有效手段。相较于传统单频段电力系统稳定器

多频段电力系统稳定器具有更多的频段支路与更高的控制自由度

可更好地抑制频率较低的振荡模式

但其整定流程与方法未见广泛研究。文中提出了一个基于多输入多输出系统频域裕度指标的多频段电力系统稳定器参数整定方法

该方法在性能指标中考虑了多个弱阻尼振荡模式

同时调整了多个多频段电力系统稳定器的幅频特性与相频特性

使它们在提供合适相位补偿量的同时最大化系统稳定裕度

且能保证各机组励磁模式稳定。所提方法的有效性通过云南电网算例得到了验证。

Abstract

Installing power system stabilizer is an effective means to enhance power system stability with small disturbances. Compared with the traditional single-band power system stabilizer

the multi-band power system stabilizer has more frequency band branches and higher control degrees of freedom

which can better suppress the oscillation mode with lower frequency

but its setting process and method have not been widely studied. A setting method of parameters for multi-band power system stabilizer based on the frequency domain margin index of multi-input-multi-output system is proposed. The method considers several weakly damped oscillation modes in the performance index

adjusts the amplitude-frequency and phase-frequency characteristics of several multi-band power system stabilizers

guarantees the designed stabilizers maximize the system stability margin while providing suitable compensation phase

and ensures the stability of the excitation mode. Case studies of Yunnan power grid of China validate the effectiveness of the proposed method.
