面对丹江口水库极度枯水的严峻形势,为了节约宝贵的发电用水,并为华中电网无功电量需求的需要,丹江口电厂于去年9月底将6号机转为排水调相运行,以便调节与改善系统的电压特性。截至元月末,该机组调相运行累计2648小时,发送无功2亿千乏时,节约水量4亿立方米。所节约的水量,可增加发电量4470万千瓦时,按现上网电价0.13元每千瓦时计算,可增加发电产值500多万元。
Faced with the severe situation of extremely dry water at Danjiangkou Reservoir, in order to save valuable power generation water, and for the need of reactive power demand of Huazhong Power Grid, Danjiangkou Power Plant turned the No. 6 plant into a drainage phased operation at the end of September last year for adjustment and improvement. System voltage characteristics. As of the end of January, the unit’s phased operation has accumulated a total of 2,648 hours, and sent 200 million kilograms of reactive power, saving 400 million cubic meters of water. The amount of water saved can increase electricity generation by 47.70 million kWh. According to the current on-grid electricity price of 0.13 yuan per kilowatt hour, it can increase the output value of electricity generation by more than 500 million yuan.
