[摘    要]对于水电厂机组运维管理来说,一旦出现全厂失压的情况,必须将机组快速开启,恢复厂内供电,一旦无法及时恢复厂用电,水电厂将面临水淹厂房的危险。水轮发电机的黑启动及孤网运行每个电厂都必须面对,文章主要对空洲电厂机组黑启动后,孤网运行进行研究,分析了当前空州电厂实际运行过程中存在的问题,并提出相应的发展意见与建议,从而增强空洲电厂实际运行效益。

Study Black Start and Isolated Grid Operation of Hydro-generator

Ling Yun-feng,Hu Peng

[Abstract]For the operation and maintenance management of hydropower plant units, once the whole plant loses pressure, the unit must be quickly turned on to restore the power supply in the plant. Once the power supply cannot be restored in time, the hydropower plant will face the danger of flooding the plant. The black-start and isolated grid operation of hydro-generators must be faced by every power plant. In this paper, after the black-start of the units in Kongzhou Power Plant, the isolated grid operation will take the entire near area to make some technical discussions and analyze the current actual operation of Kongzhou Power Plant. The problems existing in the process, and corresponding development opinions and suggestions are given, so as to enhance the actual operation efficiency of Kongzhou Power Plant.
