多机电力系统小干扰稳定性的分析和稳定器的综合

Analysis of the Small Disturbance Stability and Synthesis of Stabilizers of Multimachine Power System

本文介绍了一种对多机电力系统小干扰稳定性进行分析及稳定器(PSS)综合的计算方法和程序。文中阐述了所采用的数学模型、分析的基本方法和概念,并以一个九机电力系统为例,进行了分析和综合。对电力系统振荡模式的解耦特性,快速励磁系统的影响和建立在解耦特性基础上的新的稳定器综合方法等专题进行了详尽的研究。

A calculation method and a program description for analysis of the small disturbance stability and synthesis of stabilizers (PSS) of multimachine' power systems are presented. The math, models, the basic analysis method and concepts are expounded first, followed by a new synthesis method for the location selection and parameter design of stabilizers. A 9-machine system is explored as an example in which detailed studies are conducted on the topics of the decoupled characteristics of swing modes, the influence of high-speed exciters and the new synthesis method based on the decoupled characteristics.
