Non-intrusive load identification method and device and computer storage medium

The invention provides a non-intrusive load identification method, a non-intrusive load identification device and a computer storage medium. The non-intrusive load identification method is applied to a metadata node. The non-intrusive load identification method comprises the following steps: acquiring voltage and current signal data during steady-state operation of a plurality of load devices; acquiring first multi-dimensional electrical parameters of the plurality of load devices based on the voltage and current signal data; clustering the plurality of load devices according to the first multi-dimensional electrical parameters to obtain a plurality of clusters; a load device category is identified based on each category cluster. Through the non-intrusive load identification method, various electrical parameters of the load equipment are extracted, and effective identification of the load equipment with similar electrical characteristics is realized. 本申请提出一种非侵入式负荷识别方法、非侵入式负荷识别装置以及计算机存储介质。所述非侵入式负荷识别方法应用于一种元数据节
