Performance degradation evaluation method for outer space service power supply system, storage medium and equipment

The invention provides a performance degradation evaluation method for an outer space service power supply system. The method comprises the following steps: data acquisition: acquiring a telemetry data set and actual degradation data of a power supply system in an on-orbit service complete period of a reference spacecraft; model training: preprocessing the collected data, arranging the preprocessed data set according to the distribution of a system on a physical structure to form a matrix, and continuously changing the distribution structure of the data set and the size of a sliding window to obtain an abstract structure extractor closest to actual degradation data; degradation assessment: collecting a telemetry data set of the power supply system to be assessed, and inputting the telemetry data set into the trained abstract structure extractor based on affinity matrix analysis to obtain the performance degradation degree of the power supply system to be assessed in the state to be detected; according to the
