摘要
用 PIC16 C72单片机设计了电力三相不对称负载的功率因数补偿控制系统 ,提出了补偿电容容量的优选算法及负载性质判定算法。该系统可用于 380 V、 5 0 Hz的三相电力系统 ,与无功功率补偿屏配套使用。他可根据电网无功功率的大小与性质启动控制补偿屏中的电容器投入或切断 ,从而减少电网的无功消耗 ,改善供电质量并节约电能。
Design the innocent power factor compensate control system to dissymmetry load of power threephase with PIC16C72 singlechip microcomputer.The most excellent algorithm and the load quality selected to have put forward the compensating capacitor capacity is judged the algorithm. The available threephase power system in 380 V and 50 Hz of this system compensates the necessary use of screen with the reactive power.It can compensate the condenser input in shielding or cut off according to the dimension and the quality start control of electrical network reactive power, thus the innocent power consumption of electrical network is reduced, and the electric energy is practised thrift to the improvement power supply quality.
