摘要
储能是微电网的核心部分,可以消减一些可再生能源发电的间歇性和波动性对发电系统的影响,保证微网安全可靠的运行。针对储能单元在低压微网孤岛运行的保护,提出了一种电压反时限保护方法,以对微网故障的检测、故障类型的判别以及故障的切除。通过MATLAB仿真分析,验证了该方法的有效性,对微网实际工程中的保护提供了理论依据。
Energy storage is a core part of the micro-grid,can cut some of the impact of intermittent renewable energy and fluctuation of the power generation system to ensure the safe and reliable operation of micro-grid.For the protection of low-voltage energy storage unit in the island micro-grid operation,a new inverse voltage protection methods,micro-grid fault detection,fault type and fault removal of discrimination.By MATLAB simulation analysis,the validity of the method of micro-grid practical engineering protection provides a theoretical basis.
