矿井供电系统漏电故障定位仿真研究
|
摘要
漏电故障在矿井中的负面影响巨大,导致人员触电和瓦斯煤层等爆炸,因此漏电故障定位的研究意义重大,而当前基于各种理论的漏电保护方法可靠性不足,大多在实际应用中都时常出现误动拒动现象,为了改善矿井安全性,对矿井单相漏电故障详细分析,以零序电流为基础布置无线电流互感器,融合加权质心和四边测距提出基于WSN的新型漏电故障定位算法,该算法流程简单计算量小;仿真结果表明:该算法仅与区域大小和互感器节点数量有关,能利用传感器信号实现定位,抗干扰性强,自适应性好。
The negative effects of leakage faults in the mine are serious,causing electric shock,gas and coal dust explosion,therefore,the study on leakage fault localization is of great significance. In the paper,mine single-phase leakage faults were analyzed in detail,arrangement of wireless current transformer was based on zero sequence current,weighted centroid and four-ranging were fused to propose a new leakage fault location algorithm based on WSN,the algorithm is simple to calculate and the amount is small. The simulation results show that the algorithm is only related to area size and the transformer number of nodes,it can use the sensor signal to achieve positioning,the anti-interference is strong and the adaptability is good.
