本文介绍一种适用于中小型水电站的两级微机实时监控系统。该系统具有巡测、巡检、调节、控制、事故顺序记录、继电保护的后备保护等功能。系统硬件采用上下位两级微机结构,上位机为IBM286微机系统,下位机为工控机,上下位机之间采用双向并行中断方式通讯。系统软件采用模块化程序设计方法。各模块由管理系统(实时操作系统)实时调度。系统成功地采用模糊控制方法进行电站有功无功调节。
This article introduces a two-level microcomputer real-time monitoring system suitable for small and medium hydropower stations. The system has inspection, inspection, regulation, control, accident records, relay protection and other backup protection functions. The system hardware uses two levels of upper and lower microcomputer structure, the host computer is IBM286 microcomputer system, the lower computer is the IPC, the bi-directional parallel interrupt communication between the upper and lower computer. System software modular programming method. Each module by the management system (real-time operating system) real-time scheduling. The system successfully adopts the fuzzy control method to carry out the active and reactive power station regulation.
