將远距离輸电綫連接起来,首先建立苏联欧洲部分統一电力系統,然后建立全苏联統一电力系統,这类电力系統的发展,向科学提出了大量的科学——技术和經济方面的問題。这些問題首先是:提高复杂电力系統的稳定性,联合电力系統电压和頻率的自动調节,提高远距离輸电的輸送能力,继电保护,过电压 The long-distance power transmission lines are connected. First, some European electricity systems are unified in the Soviet Union and then a unified power system in the whole of the Soviet Union. The development of such power systems has raised a great deal of scientific-technical and economic problems in science. The first of these questions is to improve the stability of complex power systems, to automatically adjust the voltage and frequency of the power system, to improve the transmission capacity of long-distance transmission, protection against overvoltages
