预测电流控制的DSTATCOM控制器设计与实现

Research on Predictive Current Control based DSTATCOM Controller

介绍了一种DSTATCOM控制器的设计及硬件部分的具体实现。控制器由内环和外环两部分组成,外环的输出信号作为内环所需的输入信号,内环产生一个同步驱动信号,实现对电流的快速控制。硬件采用高性能数字信号处理器TMS320F2812作为DSTATCOM控制器的核心,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,本文所设计的控制器具有良好的性能。

This paper presents the design and hardware of the Distribution Static Compensator （DSTATCOM） controller composed of the inner loop and the outer loop.The output signal of the outer loop acts as the input signal of the inner loop.The inner loop engenders a synchronism drive signal to control current.The digital signal processor TMS320F2812 is used as the control center,which takes the features of its high performance processing capabilities and plenty of peripherals on chip and realizes some functions such as signal sampling, synchronization keeping,pulse signal emitting and safeguard.The Experimental results show that the controller designed has good performance.
