摘要(Abstract)：

首先介绍了中压电力线信道噪声通用模型,对现场采集的噪声进行互相关系数计算,并采用对称分量法进行相关性分析,得出三相电力系统相间噪声具有一定相关性的结论。改变单相传输模式,根据两相噪声的一致性特点,提出基于自适应最小均方误差(least-mean-square error,LMS)算法实现中压电力线通信(medium voltage power line communication,MV-PLC)的噪声对消。自适应LMS算法虽然收敛速度较慢,但是计算量小,易于实现。仿真结果表明,噪声对消方法的采用有效改善了10kV中压电力线的信噪比,为10kV配网自动化系统采用载波通信技术提供了新的实现途径。
