随着水电事业的迅速发展,为保证水力发电站的安全监控,对机组自动化提出了更高的要求,常规的监控系统已经越来越不能满足电力系统安全和经济调度的需要,监控设备更新换代势在必行。随着计算机及应用技术的发展,可将微机或以微机为基础的PLC或工控机用于水力发电站监控系统,以实现机组的顺序操作。近年的实践证明这一技术先进、性能可靠、功能强大、实时性高。
With the rapid development of hydropower industry, in order to ensure the safety monitoring of hydroelectric power stations, higher requirements are put forward on unit automation. Conventional monitoring systems have become increasingly unable to meet the needs of power system security and economic dispatch, and the monitoring equipment is upgraded Imperative. With the development of computer and application technology, microcomputer or computer-based PLC or industrial computer can be used in hydroelectric power station monitoring system to realize the sequential operation of the unit. In recent years, practice has proved that this advanced technology, reliable performance, powerful, real-time high.
