Abstract

Digital simulation modeling can meet different engineering needs, be easy to debug, and shorten the development time of engineering research. This paper analyzes the working principle of STATCOM device. Taking the three-phase H-bridge STATCOM device as an example, on the PSCAD simulation platform, using the user-defined modeling function interface technology, using C language static variables, allocating memory through common arrays, an accurate and detailed digital STATCOM model is established, and simulation experiments are carried out. The research shows that the application of user-defined module effectively makes up for the shortcomings of its own component library, and enhances the flexibility of simulation and engineering practical value. At the same time, the user-defined STATCOM device model based on PSCAD/EMTDC platform can accurately describe its compensation characteristics, and has the advantages of fast response and strong reactive power regulation ability, which can be used in the field of reactive power compensation in power system.

基于PSCAD的STATCOM自定义建模与仿真研究

数字仿真建模可以满足不同的工程需求，易于调试，缩短工程研究的开发时间。本文分析了STATCOM器件的工作原理。以三相h桥STATCOM器件为例，在PSCAD仿真平台上，采用自定义建模函数接口技术，采用C语言静态变量，通过通用数组分配内存，建立了准确详细的STATCOM数字模型，并进行了仿真实验。研究表明，自定义模块的应用有效地弥补了自身组件库的不足，增强了仿真的灵活性和工程实用价值。同时，基于PSCAD/EMTDC平台的自定义STATCOM器件模型能够准确描述其补偿特性，具有响应快、无功调节能力强等优点，可用于电力系统无功补偿领域。
