江都水利工程管理处第三抽水站改造项目中,充分利用了水力资源和泵站设备,实现了泵站同步电动机水泵机组正向抽水运行、反向变频发电运行2种运行模式。针对这一改造,开发了能够自适应于同步电动机水泵机组正向抽水运行、反向变频发电运行的高性能微机保护测控装置,用1台保护装置实现了原来需要2台装置才能实现的保护功能,既节约了工程投资、方便了现场的运行维护,又提高了站内的自动化水平。
Jiangdu Hydraulic Engineering Management Division third pumping station reconstruction project, make full use of the hydraulic resources and pumping station equipment to achieve the pumping station synchronous motor pump forward pumping operation, reverse frequency power generation operation of two kinds of operating modes. In response to this transformation, developed a high-performance microcomputer protection monitoring and control device that can adapt to the positive pumping operation of synchronous motor pump units, reverse frequency conversion power generation operation, with a protection device to achieve the original need 2 devices to achieve the protection function , Which not only saves project investment and facilitates the operation and maintenance of the site, but also improves the automation level in the station.
