济南电磁环网解环方案研究

本文阐述了电磁环网解环基本原则及主要解环方式，并以济南500kV，220kV电磁解环网为例，根据其现状及远景电网规划，提出了两种解环方案，并进行了分析计算，一方面可将电网规划与解环规划合理统一以指导电网的发展，另一方面也可避免不必要的电网建设从而节省投资。

Study on Open-loop Planning of Electromagnetic Ring in Jinan

This paper describes the fundamental principles as well as the main method of open- loop. Taking Jinan 500kV/220kV electromagnetic ring for example, in accordance with its present situation and long-term network planning, the open-loop operation mode is suggested and effect is analyzed, which not only unifies the network planning and open-loop planning rationally to guide the development of electrical network, but also avoids unnecessary construction to save investment.
