京极水电站的可变速抽水蓄能发电系统,与以往的可变速发电系统相比,运行范围更广,可实现从零到最大输出之间的调整。本刊讯日前,由日本东芝公司向日本北海道电力公司京极水电站交付的2号可变速抽水蓄能机组(200兆瓦)正式投入商业运行。抽水蓄能电站是利用电力负荷低谷时的电能抽水至上水库,在电力负荷高峰期再放水至下水库发电的水电站,可承担储能的重任。它可将电网负荷低时的多余
The variable-speed pumped storage power generation system of Jingji Hydropower Station has a wider operating range than previous variable speed power generation systems and can adjust from zero to maximum output. Recently, the No. 2 variable-speed pumped storage unit (200 MW) delivered by Japan’s Toshiba Corporation to Japan’s Hokkaido Power Company’s Jingji Hydropower Station was formally put into commercial operation. Pumped storage power station is the use of electric power when the energy pumped down to the reservoir, in the peak load of electricity to the next reservoir power generation hydropower station, can assume the heavy responsibility of energy storage. It can be redundant when the grid load is low
