摘要
详细介绍了柘溪水电厂2台250MW水轮机组在自并励励磁方式下并列对一条220kV线路进行融冰演习试验的过程,介绍了试验机组和线路的基本情况,采取了安全控制措施,分析了试验过程中遇到的问题及相应采取的对策。本次试验的成功对其他水电厂进行类似操作有一定借鉴作用,可为电网部门节省融冰规划投资提供实际案例依据,同时也开拓了线路融冰的思路。
This paper introduces the process of the ice-melting trial of two 250 MW water turbine generators on 220 kV line in self-static excitation way at the same time in Zhexi Hydro Power Plant, the basic situation of the generators and the line, and the safety control measures adopted. It also analyzes the problems met with in the test and the corresponding solutions. The success of this test may be helpful for other plants in similar tests. It may provide basis for the state grid in saving investment in ice-melting plant. At the same time, it will broaden our mind in ice-melting.
