摘要
为了解决传统馈线保护整定配合困难的问题,借助于高速发展的通信网络建立起来的面保护技术,提出一种简单易行的最小子网异或法,终端可根据自身和相邻设备的故障状态执行跳闸逻辑,共同实现本区域面保护,并且提供了针对不同的故障形式和电网结构的解决方案。该方案可适用于多电源多支线的复杂配电网。
In order to overcome difficulties in the setting of the conventional feeder protection, by means of the plane protection technology built due to the rapid development of communications network,this paper proposes a simple method of minimal subnet XOR. With this method,the terminal can execute the logic tripping according to the fault state of the equipment itself and neighboring equipment to achieve the plane protection in the region. And the paper also provides solutions for different failure modes and grid structures. This scheme is applicable to the multi-power distribution network of the multi-line circuit.
