Relay Protection of Transmission Line in the Micro-Grid Based on Frequency Modulation

Yifei Xu, Huan Ma, Jiao He, and Dehua Zhang
Abstract—In recent years, the development of the micro-grid technology is promoted rapidly. In this paper, considering the fault characteristics of the micro-grid and the insufficiency of micro-grid relay protection, relay protection of transmission line applied in the micro-grid based on frequency modulation is proposed firstly. Then, differences between the micro-grid relay protection and the traditional one are introduced. After that, the operational principle and the whole working process of the frequency modulation are analyzed. Finally, by simulation and experiments, the novel proposed frequency modulation method is proved correct and practical.

Index Terms—Micro-grid, inverter, frequency modulation, relay protection, frequency conversion.
