电磁环网方式与分层分区运行方式之决策

Comparison of Operation Mode of Electromagnetic Loop Network and Voltage-Grading & District-Dividing

电力系统动态发展,规模逐渐扩大,在发展的不同阶段,电网分别出现了电磁环网和分层分区运行方式。这2种运行方式有不同的适应性,有区别于对方的优缺点,并且可以相互转化,必须根据电网发展的具体阶段决定采用何种方式运行,而不能笼统的说哪种方式更好。本文比较了这2种运行方式,并介绍了进行方式决策的方法。

Power system keeps developing all the time. In its different developing stage, the operation mode of electromagnetic loop network and voltagegrading ＆ district-dividing appear respectively. Both operation modes have their adaptability. This compares them and presents the principle to adopt them paper.
