EXC9100型励磁系统在三河口水电站的设计与研究

Design and Study of EXC9100 Excitation System in Sanhekou Hydropower Station

引汉济渭工程是陕西省境内的一项大型跨流域调水工程。三河口水电站是引汉济渭工程的调蓄中枢,设计有工频发电、变频发电、工频抽水、变频抽水等多种运行工况,需对励磁系统进行特殊设计。其励磁系统采用在泵站、电站等多种运行工况下有较多工程经验的EXC9100型励磁系统。本文从设计角度出发,详细介绍了三河口水电站励磁系统的设计,讨论了多种运行工况下对励磁系统的特殊要求,为同类型水电站励磁系统的设计工作提供借鉴和参考。

The Yinhan Jiwei Engineering is a large-scale inter-basin water-transfer project in Shaanxi Province.Sanhekou Hydropower Station is the regulation and storage center of Yinhan Jiwei Project.It is designed of various operating conditions for Sanhekou Hydropower Station such as power-frequency power generation,frequency-conversion power generation,power-frequency pumping,frequency-conversion pumping etc.,so its excitation system needs to be designed specially.The excitation system adopts EXC9100 excitation system that has more engineering experience in pumping station,power station and other operating conditions.From the design point of view,the paper introduces the design of excitation system of Sanhekou Hydropower Station in details,and discusses the special requirements for excitation system under various operating conditions to provide reference for excitation system designs of similar hydropower stations.
