Design and Implementation of Reactive Power Compensation System Based on MSP430

针对电网中无功补偿问题,介绍了一种基于MSP430F449的无功补偿系统,简要地论述了系统的硬件和软件设计。系统能够通过430F449内部自带的A/DC12模块实现电流、电压的采集,同时利用定时器的捕获功能来计算信号相位差,求得输出控制量,控制自动投切并联补偿电容器组,实现系统的无功补偿。

Aiming at the topic of reactive power compensation in electric power grid, a reactive power compensation system based on MSP430F449 is introduced. The design for hardware and software of the system is described briefly. Through A/DCI2 module inside 430F449, acquisition of currents and voltages can be conducted by the system. In addition,by using the capture capability of the timer,phase difference of the signals can be calculated to derive the control output to control the auto-switching shunt compensation capacitor banks for realizing reactive power compensation.
