| 摘 要： | 根据特高压豫北站建成后河南电网将面对的500/220 kV母线三相短路电流超标的状况，对其500/220 kV电磁环网解环进行研究。基于目前的分区模式提出解环方案，并验证各方案实施的可行性。解环后河南电网将形成十六片电网分区供电模式，在保证电网安全稳定运行的前提下，降低了系统母线三相短路电流水平，能够最大限度发挥电网的投资效益，促进500/220 kV电网协调发展。通过对河南电网的解环研究，提炼出特高压电网环境下处理500/220 kV电网电磁环网解环的技术原则，可为电网中长期规划及其工程实施提供参考。

| Abstract: | The level of three-phase short-circuit current of 500/220 kV bus will exceed standard in Henan power grid after the completion of Ultra-High Voltage (UHV) Yubei station. The opening of 500/220 kV electromagnetic ring network is studied. The solution to electromagnetic ring opening is proposed based on current partitioning mode,and the feasibility of all the schemes is verified. After the ring opening,Henan grid will be divided to 16 areas to supply electric power. Under the premise of grid security and stab... |
