摘　　要：电力系统运行过程中要求负荷用电量与总容量相互匹配,电能损耗需及时得到补偿,同时避免出现欠补偿和过补偿现象。为避免外部干扰加大采样参数波动误差而影响负荷电能补偿效果,设计了一种包含数据采集电路、电能补偿与投切电路、微机控制电路的自动投切系统。该系统将晶体管用作开关,以负荷的功率因子作为自动投切的判断依据,主要借助微机控制电路的主控制器实现自动监控和投切功能。仿真实验结果表明,该系统可以自动根据负荷电能的变化实时进行损耗补偿,能快速实现负荷侧电流与电压总量平衡,增强电网运行的稳定性。In the process of power system operation,load power consumption and total capacity are required to match each other;power loss needs to be compensated in time,at the same timethe phenomenon of under compensation and over compensation should be avoided.In order to avoid external interference increasing the fluctuation error of sampling parameters,so as to affect the effect of load power compensation,an automatic switching system including data acquisition circuit,electric energy compensation and switching circuit and microcomputer control circuit is designed.The crystal tube is used as the switch,and the power factor of the load is used as the judgment basis for automatic switching,the function of automatic monitoring and switching is realized by the main controller of microcomputer control circuit.The simulation results show that,the system can automatically compensate the loss according to the change of load power;it can quickly realize the total balance of load side current,enhance the stability of power grid operation.
