摘　　要：本文介绍了适用于电力系统各种等级变电站的电压和无功功率综合自控系统的具体实现方法。该系统以 AT89C52单片机为核心 ,实现系统的在线闭环控制。给出了系统的总体方案和系统的硬件结构框图以及软件流程。针对系统特点 ,提出了许多抗干扰措施 。This paper presents the concrete practice of a synthetic control system of voltage and reactive power applicable to various types of substation of an electric power system. This control system takes the AT89C52 microcomputer as its core to realize its on line closed loop. The paper also gives an overall scheme of the system including its hardware configuration and software flow chart. In view of the system features, the paper puts forward various measures against interferences. The results show that these measures are successful in some extent.
