四级电站技术供水运行方式探讨

Research on technical water supply mode in fourth cascade hydropower station

水电站厂房技术供水是否合理，直接关系到机组的安全运行和电站的经济效益。对华电云南以礼河发电厂四级电站技术供水系统存在的主要问题进行了分析，提出将供水泵改为变频恒压供水泵的改造方案，该方案可显著增加电站运行可靠性，为保证电站主设备运行打下良好基础。

The rationality of the technical water supply of the hydropower station buildings directly related to the safe operation of the unit and the economical benefit of the hydropower station. The main problems existing in the technical water supply system of the Fourth Cascade Hydropower Station of Huadian Yunnan Yilihe Hydropower Plant were analyzed. A reformation scheme was put forward, in which the water supply pump will be replaced by the variable frequency and constant pressure pump. The scheme can increase the operation reliability of the hydropower station remarkably and provide the good foundation for operation of the main equipments in the hydropower station.
