静止同步补偿器的标幺化模型及开环响应时间常数分析

静止同步补偿器（ＳＴＡＴＣＯＭ）的标幺化建模是迄今为止国内外都没有得到解决的难题。作者在开发 同容量的ＳＴＡＴＣＯＭ装置所积累的理论和工程经验的基础上，提出了一个真正标幺化意义上的ＳＴＡＴＣＯＭ数学模型，并以此数学模型为基础，揭示了ＳＴＡＴＣＯＭ开环响应时间常数与装置主电路参数的相互关系。该模型为ＳＴＡＴＣＯＭ的各种稳态暂态性能分析及控制器参数设计提供了系统化方法。

A PER-UNIT STATCOM MODEL AND ANALYSIS OF OPEN LOOP RESPONSE TIME CONSTANT

The per unit modeling technique for STATCOM (Static Synchronous Compensator) is a difficult problem that has not been solved all over the world. Based on the theoretical research and engineering experience in developing three different rating STATCOMs, authors proposed a per unit STATCOM mathematical model in this paper.As an illustration of application, the relationship between the open loop response time constant and the main circuit parameters is discussed with the per unit model.This new model provides a systematic foundation for performance analysis and controller parameters determination.
