摘要
感应电动机模型是电力系统运行与控制理论研究和工程仿真计算中最常用的负荷模型 ,其运行特性对电力系统的运行行为有重要影响 .深入研究了感应电动机模型结构与其行为模式之间的关系 :阐述并提出了既能描述负荷的功率恢复特性 ,又能描述负荷的低电压失稳特性的综合负荷模型结构应当满足的必要条件 ;提出适合于电压稳定分析的综合负荷模型的基本结构形式 .
The essential structure and behavior mode of one order dynamic model of induction motor based on research for the relationship between typical structure of one order dynamic system and its behavior mode is studied.The essential conditions of model structure of synthetic power load being able to describe not only power recovery characteristics but also instability characteristics are presented.The basic structure and modeling method of power load model suiting for voltage stability analysis are presented.
