华东核心网架中长期发展模式

Development pattern of medium and long-term for core network in East China Power Grid

华东电网将逐步发展为多特高压交直流输入、交直流并列运行的特大型受端电网,现有500kV电网的发展模式将发生较大变化。根据华东电网的特点以及规划特高压落点的布局,对华东电网进行板块划分,通过对电网的供电安全分析和短路电流计算,研究板块之间的相互联系模式及短路电流控制措施,从而明确未来华东500kV电网的功能定位及与特高压电网协调发展的运行模式。

East China Power Grid will be gradually developed into a large receiving power grid with muhi-UHV AC and DC input, AC and DC parallel operation. The existing 500 kV power grid development pattern will have great changes. Based on the characteristics of East China Power Grid, as well as UHV site layout, division of the East China Power Grid to several part, and through the security analysis and short-circuit current calculation, the interconnections between those part and the measures for short-circuit current control were studied, and the development pattern was envisaged for East China Power Grid after UHV power grid put into operation.
