摘要
复合开关采用可控硅与交流接触器并联工作结构,可以实现对电容器的智能投切,从而避免系统的瞬间冲击电流和电网波动。将复合开关应用于无功补偿装置,并采用串联电抗器的方法来抑制谐波,建立了仿真模型,进行了复合开关投切过程和串联电抗器抑制谐波的仿真研究。结果表明:复合开关明显改善了投切过程,串联电抗器对谐波有较强的抑制功能,实现了无功补偿装置的安全稳定补偿。
Compound switches are featured by the working structure of a parallel connection of thyristors and AC con- tactors, contributing to intelligent switching, which focuses on avoiding system transient impact current and fluctuation to power grid. Compound switches are proposed to be applied to the equipment of reactive power compensation while se- ries reactors are to be used to curb harmonic, and then a simulation model has been established so as to simulate the switching of compound switches as well as to curb harmonic with series reactors. The results show that compound swit- ches are conducive to streamline the switching process and that series reactors excels in suppressing harmonic, both of which pave the way for both security and stability of compensation.
