静止无功发生器半实物仿真实验平台的电路设计

摘要

根据静止无功发生器(SVG)的工作原理,以TMS320F2812为主控芯片,搭建了静止无功发生器半实物仿真实验平台,完成了主电路、采集电路、驱动电路、保护电路及辅助电路的设计,给出主要电路的原理图.该仿真实验平台结构简单、功能完善、采用模块化设计,能够验证各种控制算法,可供学生分组协作实验,帮助学生理解无功功率补偿的工作原理和控制策略等相关知识.%According to the working principle of SVG(cstatic var generator), this paper builds a semi-physical simulation platform with TMS320F2812 as the main control chip, and completes the design of main circuit, acquisition circuit, drive circuit, protection circuit and auxiliary circuit.The simulation platform has a clear idea, a simple structure, complete functions and modular design, which can promote students' collaborative and group learning.Objects of the simulation platform can verify various control algorithms and help students understand the principle of reactive power compensation, control strategy, and other relevant knowledge.
