夜幕降临,璀灿的灯光把城市照耀得如同白昼,供电站里的供电负荷指示表上的指针急剧上升,供电出现不足,电压下降;而当夜深人静时,供电负荷指示表上指针又急速下降,电力过剩、电压升高。那么,如何解决这供电与用电的矛盾呢?一是将深夜用电低谷时过剩的电能储存起来,待来日电力不足时供给用户,目前日本等一些国家正在从事此项研究,已
As night fell, the bright lights shone the city like day, the pointer on the power supply load indicator in the power supply station rose sharply, the power supply was insufficient, the voltage dropped; and when the dead of night, the pointer on the power supply load indicator dropped sharply. Excess electricity and voltage increase. So, how to solve this contradiction between electricity supply and electricity? First, to store excess electricity during late-night electricity consumption, and to supply electricity to consumers when electricity is not available in the coming days. At present, Japan and some other countries are engaged in this research.
