水轮机调速器功率模式在索风营电厂的运行实践

Operation practice of hydraulic turbine governor power mode in Suofengying Hydropower Plant

贵州乌江水电开发有限责任公司索风营发电厂原有调速器在功能及精度上存在着各种各样的问题,不能满足运行的需求。分析了出现问题的原因,提出了解决方案。通过对水轮机调速器的换型改造,实现了调速器功率闭环模式的运行,其经验可为其他水电企业实现类似的调速器功率模式提供借鉴。

The original governor of the Suofengying Hydropower Plant of Wujiang Company has various defects in its function and accuracy and can not satisfy the operation requirement. The reasons of the defects were analyzed,and the solutions were proposed. The original hydraulic turbine governor was replaced by a new type one. The governor can operate in power closed- loop mode. The experiences of this paper can be used as reference for other hydropower enterprises to solve similar problems.
