摘要
我国目前最为主要的无功补偿方式是采用并联电容器,在使用简单的机械开关投切并联电容器时会在投切瞬间产生极大的涌流和过电压。针对此问题提出一种新型复合开关结构,且在MATLAB软件平台上建立相应的仿真模型和搭建低压模拟试验平台,验证其可行性。通过仿真和模拟试验可以看出,新型复合开关结构相对简单,能够有效地抑制并联电容器投切过程中的涌流和过电压。
The most widely used method for reactive power compensation is to adopt parallel capacitors. Using simple mechanical switch to switch the compensation capacitors will produce surge and over-voltage. A new compound switch structure was proposed for this problem. Simulation model with MATLAB and low voltage experimental platform were built to verify its feasibility. The simulation and experiment show that the new compound switch can effectively suppress the inrush current and overvoltage during the switching process of the parallel capacitor.
