摘要
针对现有井下高压电网漏电保护系统大多存在可靠性较差、误判率较高的缺点,提出了一种基于ZigBee无线传感器网络的井下电网漏电保护系统的设计方案。该系统以CC2530射频模块为核心,采用改进型的RSSI定位算法定位故障,实现了远程故障定位功能,降低了误判率。测试结果表明,该系统性能稳定,能够满足井下电网漏电保护要求。
In view of shortcomings such as poor reliability, high error rate existed in current leakage protection system of underground high-voltage power grid, a design scheme of leakage protection system of underground power grid based on ZigBee wireless sensor network was put forward. The system adopts CC2530 as core and uses improved RSSI location algorithm to locate fault position, which realizes remote fault location, and reduces error rate. The test results show that performance of the system is stable, and meets requirements of leakage protection of underground power grid.
