摘要：

摘要：云南华电鲁地拉水电有限公司机组的技术供水系统配置了大量的插入式流量计，运行维护工作量大，流量计性能单一、质量不稳定，降低了机组自动化开机的成功率。通过分析论证，取消不必要的流量计，将插入式流量计更换为响应灵敏度高、测量精度高、稳定性好且安装工艺简单的套管式流量计，并对发电机组技术供水投入成功的条件进行了简化和优化，可缩短水轮发电机组开机时间，保证发电机组安全稳定运行。

Abstract:

Abstract:For the technical water supply system of power unit in Yunan Huadian Ludila Hydropower Company Limited, a large number of plugin flowmeters are allocated. And the success rate of unit automatic start up is decreased because of the single function, unstable quality and large operation maintenance workload of plugin flowmeters. Through analysis and demonstration, some measurements are adopted to ensure the safe and stable operation of generating unit. The first one is removing unnecessary flowmeters, the second one is replacing the plugin flowmeters by sleevetype flowmeters, which have the advantages of high response sensitivity, high measurement accuracy, good stability and simple installation technology, and the last one is simplifying and optimizing the operation success conditions of technical water supply of power unit, which could shorten the startup time of hydrogenerator unit.
