Research on SvC System Based on PI control Method of C.P.Steinmetz Balancing Principle

瞬时电流控制补偿策略来实现三相平衡化和功率因数的补偿,从理论上分析了这种方法的正确性;然后,用MATLAB/Simulink进行了仿真,通过仿真和实验发现,静止无功补偿控制系统具有一定的合理性和先进性,能够达到较快的响应和较好的补偿精度,可实现对三相不平衡负载的快速动态无功补偿,达到了预期的补偿效果。

The instantaneous current control compensation strategy is used to achieve three-phase balance and power factor compensation.Theoretically analyzed the correctness of this method.Then,with MATLAB/Simulink is simulated,through the simulation and experimental results show that the design of the static reactive compensation control system has certain rationality and advanced nature,can achieve quicker response and good compensation accuracy,can realize the unbalanced three-phase load of the quick and dynamic reactive power compensation,achieve the expected effect of compensation.
