Abstract
本申请涉及一种配微网电力设备的局部放电检测方法、装置、计算机设备、计算机可读存储介质和计算机程序产品。包括：通过多通道局放传感器采集配微网电力设备的多个通道类型的局部放电数据；若多通道局放传感器为多个多通道局放传感器，则将局部放电数据按照通道类型拼接为高维放电向量并进行重构，得到重构向量；基于高维放电向量和重构向量确定全局重构残差及各通道类型的单维重构残差；若全局重构残差存在异常，基于各通道类型的单维重构残差进行单维异常定位，得到初步判断结果；基于初步判断结果，确定目标单维重构残差，对目标单维重构残差进行去噪和跨类型相关分析，得到局部放电检测结果。采用本方法能够更加准确的检测局部放电情况。
