摘要:

漏电流容性分量普遍存在于配电系统中,对漏电监控产生显著干扰,从而影响了电气火灾监控报警的准确性。搭建漏电流试验平台,模拟实际线路情况,设计数据采集系统实时显示,采集4种电压模式、4种负载模式在阻性漏电和容性漏电情况下的数据。提出利用多层全连接BP神经网络对漏电流阻性分量进行预测,消除漏电流容性分量。经测试,所提模型对漏电流阻性分量预测误差仅1.08%,能有效识别漏电流阻性分量,提高电气火灾预警的准确性。

Abstract:

The capacitive component leakage current (CCLC) commonly exists in power distribution systems.However,it significantly interferes the leakage current measurement and reduces the accuracy of electrical fire monitoring.The leakage current test platform is built to simulate the actual circuit condition,and a data acquisition system is designed to display and acquire the data of four voltage modes and four load modes under the resistive leakage and capacitive leakage conditions.A multilayer fully connected BP neural network is used to eliminate the CCLC by predicting the resistive component leakage current (RCLC).The test results show that the prediction error of the RCLC reaches only 1.08%,which can prove that the methd can effectively identify the RCLC and improve the accuracy of electrical fire alarming.

Key words: capacitive component leakage current (CCLC), electrical fire monitoring, multilayer fully connected neural network, capacitive component leakage current compensation
