摘要
220kV电网作为超高压输电网和高压配电网之间的衔接电网,其发展趋势会给电力网络带来很大的影响。本文从经济性、上下级电网协调性、短路水平、负荷密度等角度分析了影响220kV电网发展的一些因素。
The development trend of 220 kV power grid, which is the connection between the ultra high voltage transmission network and the high voltage distribution network, will have a great impact on the power network. This paper analyzes some factors that affect the development of 220 kV power grid from several aspects.
