摘　　要：随着电力系统的发展,电网的平稳运行愈发关键。电网重过载和低电压问题是当前电力行业面临的重要挑战,这些问题会导致设备损坏、电力中断甚至安全事故,为此提出基于多源数据融合的电网重过载和低电压监控方法。通过采集和预处理电网实时运行数据、历史数据等多源数据,利用主成分分析提取多源数据特征,采用D-S理论融合多源数据特征。根据电网重过载和低电压特征与深层自动编码器实现对电网重过载和低电压的实时监控和预警。实验结果表明,该方法提高了电网重过载和低电压监控的准确性,能够为电网的安全稳定运行提供了技术支持。In the paper,propose heavy overload of the power network and low voltage monitoring method based on multisource datafusion.Through collecting and pretrecting power network real-time operation data,history data and multisource data,make use of main compoment to draw the multisource data characteristics and adopt D-S theory to fuse the multisource data characteristics.According to the heavy overload of the power network and deep layer automation coder,achieve real-time monitoring and early warning to the heavy overload of the power network and the low voltage.The experimental results show the nethod improve accuracy of the heavy overload of the power network and low voltage monitoring,which can provide technology support for safe and stable operation of the power network.
