摘要
在励磁系统中加入电力系统稳定器 (PSS) ,增加阻尼 ,有利于抑制低频振荡。提出了利用免疫算法为单机无穷大系统设计PSS。它将PSS的整个设计过程转化为一组参数进行寻优的过程 ,利用IA的特点 ,提高了多参数寻优的效率。仿真结果表明 ,利用该方法设计的PSS性能有了较大的提高。
Power system stabilizer (PSS) are added to excitation systems to enhance the damping during low frequency oscillations. In this paper, the design of PSS for single machine connected to an infinite bus using Immune Algorithm (IA) was proposed. It transfers the process of design of PSS to the process of optimization for a set of parameters. By using IA, the efficiency of optimization for multi-parameter was promoted. This method gives sa- tisfactory results for the design of PSS.
