摘要
交流微电网具有诸多的优点,是未来重要的发展方向。但是当交流微电网内部发生故障时,较难检测出故障,且由于电流的双向流动,难以确定故障位置。且在低压电网中,很多节点只能获取电流信息,难以获取电压信息,因此有必要研究仅利用电流信息的微电网故障区间定位方法。文章使用PSCAD对故障进行仿真,对交流微电网故障区间定位算法进行仿真验证。
AC Micro-Grid has many advantages and it is an important development direction in the future.However,when a fault occurs in the AC Micro-Grid,it is difficult to detect the fault,and it is difficult to determine the fault location due to the bidirectional flow of current.Moreover,in the low-voltage power grid,many nodes can only obtain current information and it is difficult to obtain voltage information.Therefore,it is necessary to study the fault interval location method of Micro-Grid using only current information.In this paper,PSCAD is used to simulate the fault and the fault interval location algorithm of AC Micro-Grid is simulated and verified.
