摘要
传统的配电网馈线自动化中,保护的快速性与选择性是不可调和的矛盾,为此引入了具有数据采集与通信功能的无线传感器网络,并结合当前馈线自动化中广泛应用的重合器与分段器,给出了一种基于无线传感器网络的配电网故障定位及保护方案。通过网络模型的搭建以及故障分析,得出了一种参考相邻开关故障状态的保护判据,并通过仿真验证了方案的可行性。
Wireless sensor networks, which can collect data and communicate, were introduced into the distribution system to settle conflict between the rapidity of protection and selectivity. Combined with the recloser and sectionalizer, which are widely used in current feed line automation, this paper presented a kind of fault location and protection scheme based on wireless sensor networks. Through establishing network model and fault analysis, a protection criterion of referring to the adjacent switch state was obtained. The protection scheme was also verified to be feasible by simulation research.
