摘要
介绍了一种基于单DSP控制的新型静止无功补偿控制器的设计。该控制器将瞬时无功理论和同步旋转坐标变换运用到无功检测算法中,所设计的控制器控制性能稳定、现场抗干扰能力强;具有分相电压电流采集能力并采用简单的平均检测算法;采用DSP数字信号处理器作为控制核心,软件主要采用C语言编程,硬件软件设计均预留了充足的扩展空间。样机测试表明设计正确,运行稳定,达到了预期要求。
The new design of DSP-based SVC controller is introduced. In this controller, the instantaneous reactive power theory and synchronous reference frame transformation are adopted in VAR detection algorithm. The controller is stable in control and good at EMC. In addition, it is able to collect separate three-phase voltage and current, and uses a simple average detection algorithm. With the DSP digital signal processor as the control core, and C language for software programming, sufficient expanding space is reserved for future redesign of hardware and software. The trial operation of the prototype shows that the good results of design meet expected requirements.
