摘要
为了使静止型无功功率补偿器准确计算出系统非线性所需补偿的电流并进行实时补偿,分析了电压全周期过零检测电路的基本原理,给出了一种基于Protel 99SE仿真的无锁相环交流电压全周期过零检测电路,对所提出的电路进行了参数设计、仿真和实验,结果表明设计的无锁相环电压全周期过零检测电路的正确性和可行性。
To make the current get an effective compensation with Static Var Compensator （SVC） in power system with the distortion loads,we analys the basic theory about the detector ciucuit of voltage cross zero, design the detector circuit of voltage cross zero in complete period without Phase Lock Loop （PLL）, Simulation and experiment are executed about the main circuit after calculated the ciucuit parameters,in result,the correctness and the feasibility of the main circuit are validated.
