摘　　要：为提高无功补偿系统的实时性和控制精度,设计了一种基于ARM11处理器S3C6410的无功补偿控制系统。该系统采用了实时多任务、可移植、可裁剪的嵌入式μC/OS-II操作系统。为解决电容投切振荡所引起的电压波动问题,改进了传统的模糊控制投切策略;为防止无功不平衡所引起的过欠补偿问题,采用了共分补相结合的投切方式。该系统可自动采样计算实现无功自动调节,具有可靠性高、实时性好、投切振荡少的特点,应用前景广阔。In order to improve the real-time feature and the control accuracy, an embedded reactive power compensation system based on ARM II processor S3C6410 is designed. The system adopts a real-time multi-tasking, portable, scalable oper- ating system μ C/OS-II. To prevent the problem of voltage fluctuation due to capacitor switching and the over or under compensation problem due to the three phase unbalanced, an improved fuzzy control strategy and a combined method are adopted. The functions as automatic sampling calculation and at, tomatic adjustment are realized. With broad applica- tion prospect, the system has good performances as higher reliability, better real-time and less oscillation.
