摘要
分析了采用三相变流器为主电路结构的静止无功发生器 (SVG)装置的工作原理。控制上采用了基于瞬时无功功率理论的控制方法 ,根据不同的补偿要求 ,提出了两种具体的控制方案 ,分别给出了数学公式并分析各自优缺点 ,并对其中的一种情况给出了基于Matlab的仿真。
This paper deals with a static VAR generator with an instantaneous reactive power theory based control strategy which employs a three phase voltage source inverter. According to the different compensating objects, two specific control methods are presented and their formulas are also given respectively. Simulated results obtained with Matlab are also given. Finally, experiments based on the two methods are presented and analyzed.
