The Simulation Research on STATCOM Based on EMTDC/PSCAD

电力无功补偿是输配电系统的重要部分之一,而静止同步补偿器是目前较好的无功补偿装置,是柔性交流输电系统的核心。分析了静止同步补偿器的工作基本原理,以十二脉冲电压型STATCOM装置为例,采用PSCAD分析软件对其进行仿真实验。研究表明,在PSCAD环境下建立十二脉冲电压型STATCOM装置的模型能够准确地描述其动态特性,具有响应速度快、有功功率调节能力强的优势,可用于电力系统无功补偿领域。

Reactive power compensation is an important part of power transmission and distribution system,while STATCOM is a better reactive compensation devices and is the core of flexible AC transmission system.The basic principle of STATCOM is analyzed in this paper and 12-pulse voltage STATCOM device is simulated by PSCAD software.The result shows that the model of 12-pulse voltage STATCOM device can accurately describe its dynamic characteristics in PSCAD.Its response speed is fast and the ability of regulating the active power is strong.So it can be used in compensation reactive power field.
