水电站110kV电气设备选择技术研究

Research on Choice of Electrical Equipment of 110 kV in Hydroelectric Power Station

在中国电力系统迅速发展的大趋势下,西流水电站的设计也应业主要求采用了最新的设计理念,电气设备也遵循了智能化、小型化的设计思路.在110 kV户外高压设备的选型上通过对AIS、GIS、PASS三个方案进行比较后最终选用了当前最先进的开关装置(Plug And Switch System,简称PASS),也称插接式开关装置.电站已经运行6年,目前PASS在本电站的成功应用已使得PASS被水电行业逐渐推广.

With the rapid development of China＇ s electric power system, Westflow Station design uses the latest design concepts, and its electrical equipments are intelligeut and small. When choosing the 110 kV high voltage outdoor equipmeut,the most advanced switching equipment （play and switch system which is called PASS, also called play - switch device） is selected finally through comparing AIS,GIS with PASS.The station has been operating for six years and because of the successful application of PASS in the station, the PASS device has been promoted gradually in Gansu province＇s hydro- power industry.
