摘要
煤矿高压供电系统大部分故障为单相接地等线路漏电故障,对煤矿安全影响重大。本文针对煤矿高压电网漏电故障问题,应用MATLAB软件仿真了高压电网单相接地故障过程,对故障特征进行了分析。在分析的基础上,将无线传感器网络技术应用于电网漏电保护,对无线保护系统的总体框架进行了硬件和软件设计,对故障监测及无线传感器节点进行了分析验证。
Most of the failures in the coal mine high voltage power supply system occur in the single-phase grounding and other lines leakage fault, which has great infuence on the coal mine safety. In this paper, the failure fault of high voltage power grid in coal mine is simulated by MATLAB software, and the fault characteristics are analyzed. On the basis of the analysis, the wireless sensor network technology is applied to the leakage protection of the power grid, and the hardware and software design of the overall framework of the wireless protection system is carried out. The fault monitoring and the wireless sensor node are analyzed and verifed.
