基于TMS320F2812的DSTATCOM的研究

为了实现对电网的实时动态无功补偿,笔者提出一种采用高性能数字信号处理器TMS320FE812作为控制核心的DSTATCOM控制器,利用其数据处理能力强、片内外设丰富的特点,实现了信号采样、同步保持、脉冲信号发出及保护等功能。实验结果表明,所设计的控制器具有硬件电路简单、实时性好、功能完善、可靠性高和抗干扰能力强等优点,完全可以满足DSTATCOM的实时性、多功能和多目标协调控制、处理算法复杂等要求。

TMS320F2812 Based DSTATCOM Controller

In order to achieve real-time dynamic reactive power compensation for power system,this paper presents a DSTATCOM controller,with the digital signal processor TMS320F2812 as its control center.This controller takes advantage of high processing capabilities and rich chip peripherals of TMS320F2812,and realizes such functions as signal sampling, synchronization keeping,pulse signal emitting and safeguard.Experimental results show that the controller has the advantages of simple circuit,good real-time,perfect function,high reliability and anti-jamming,and can satisfy completely the needs for DSTATCOM,including real-time,coordinated control between multiple functions and multiple goals,complex processing arithmetic,and so on.
