摘　　要：针对高压电机传统的无功就地补偿的问题,介绍了一种基于 TI 公司的16位单片机 MSP430为主控制系统的高压电机无功自动补偿装置,详细的介绍了系统的结构及软硬件设计。MSP430单片机根据测量的电机功率因数值,执行 PID 控制,其输出控制量,经光电隔离和放大,连续控制可控硅的导通角调节电容器的电流,使高压电机的功率因数达到理想的设定值。According to the problem of traditional reactive local compensation of high voltage electromotor, this paper introduces a reactive power compensation device of high voltage electromotor in which 16 unit MSP430s of TI company act as a key control system, and introduces the structure of the system and the design of hardware and software in detail. MSP430 performances PID control according to measured electromotor power factor value, its exportation control quantity, through light electricity insulating and enlargement, controls lead angle of SCR to regulate current of capacitor, make the power factor of high voltage electromotor attain ideal initial value.
