基于微电网的单电源进线站用电可靠性研究

Research on Power Reliability of Single Power Station Based on Microgrid

站用电作为给变电站内部各用电负荷供电的电源系统,其可靠性要求极高。传统站用电都来源于电网系统,为提高沙戈荒边地区单电源进线的站用电系统的可靠性,基于含微电网的单电源进线站用电系统进行分析。研究结果表明,将储能和光伏风电等新能源构成的微电网作为站用电系统电源的补充,在变电站发生故障情况下,可极大延长站内负荷的供电时间,提高站内的供电可靠性且便于检修和快速恢复供电。

As a power supply system for each power load inside the substation,the reliability requirement of station power consumption is extremely high.And traditional station power consumption comes from power grid system,In order to improve the reliability of the station power system with single power supply in the Shage wasteland area,the paper analyzes the power system of single power supply station with micro grid.The results show that,the microgrid composed of new energy sources such as energy storage and photovoltaic wind power is used as a supplement to the power supply of the station power system,in the case of substation failure,it can greatly extend the power supply time of the load in the station,improve the power supply reliability in the station,and facilitate maintenance and rapid recovery of power supply.
