The power factor compensation control system of three-phase unbalanced load in power system is designed with PIC16 C72 microcontroller, and the optimal algorithm of compensating capacitance capacity and the algorithm of determining the load’s quality are proposed. The system can be used for 380 V, 50 Hz three-phase power system, and reactive power compensation screen supporting the use of. According to the size and nature of the reactive power of the grid, he can start and control the capacitor in the compensation screen to turn on or off, thereby reducing the reactive power consumption of the grid, improving the power supply quality and saving energy.
