摘　　要：随着特高压电网全面建设投产,1 000/500/220 k V电磁环网将不断出现,对500/220 k V电磁环网开环提出了新的需求。本文着重对500/220 k V电磁环网开环的基本原则、主要开环方式以及开环方案制定步骤进行了阐述,并以鄂西北500/220 k V电磁环网为例,结合其现状及远景电网规划,对其实施逐步开环,在解决鄂西北电网存在的电磁环网运行风险的同时,将电网规划与开环策略统筹考虑,指导鄂西北电网的发展。With the completion of UHV power grid and the 1 000/500/220 k V electromagneticloop network will continue to appear, the urgency of breaking 500/220 k V electromagnetic loop net-work is more important. This article focuses on the basic principles of breaking up 500/220 k V elec-tromagnetic loop network, the main open-loop method and the steps of formulating open-loop plan.Taking 500/220 k V electromagnetic loop network of Northwestern Hubei as example, open-loop planwith present situation and planning is put forward. The open-loop plan will solve the risks of grid,connect the open-loop plan and the grid planning, and guide the development of the grid.
