微电网继电保护方案研究

Research on Relay Protection Scheme of Microgrid

随着电力科技的飞速发展,微电网得到广泛的应用,该技术可以提供稳定、安全、高效的电能,这就给传统继电保护方案带来了挑战。由于微电网可以独立运行,且对变流器的故障电流具有一定的要求,传统继电保护难以满足微电网的运行需求,为了确保配电网的安全运行。文章首先阐述微电网继电保护的模式,探析了微电网继电保护的重点难点,最后对微电网继电保护方案与方案构建要点进行探究,希望为有关人士提供有价值的参考。

With the rapid development of power technology,microgrid has been widely used.This technology can provide stable,safe,and efficient electrical energy.Under this trend,it has brought challenges to traditional relay protection schemes.This is because microgrid can Independent operation,and has certain requirements for the fault current of the converter,which is difficult to meet the operation requirements of the microgrid,in order to effectively ensure the application value of the distribution network.This article first elaborates the microgrid relay protection mode,then explores the major and difficult points of microgrid relay protection,and finally explores the microgrid relay protection scheme and the key points of its construction,hoping to provide valuable references for relevant parties.
