Differentiated electricity customer operation and maintenance method, system and device and storage medium

The invention discloses a differentiated electricity customer operation and maintenance method, system and device and a storage medium. The method comprises the following steps: preprocessing data to obtain a two-dimensional spectrum amplitude matrix; the two-dimensional spectrum amplitude matrix is compressed and stored, and similarity calculation is performed on compressed data; based on the calculated similarity, clustering the compressed data to obtain a clustering result; associating a clustering result with a service type to form a unified label; and based on the unified label, in combination with the power supply guarantee schemes of different levels of electricity customers, differentiated management is carried out on the customers. Automatic identification of user levels, automatic association of electric equipment and power grid operation monitoring of important clients are realized, and the problem that the important clients and the electric equipment of the important clients are still manually con
