| description | The invention provides a health state assessment method and device for a wind generating set, and the method comprises the steps of obtaining SCADA data of the wind generating set collected by an SCADA system, the SCADA data comprising a plurality of data groups, and each data group comprising power data and temperature data of the wind generating set at the same moment; based on the power data, dividing the plurality of data groups into different power intervals, each power interval comprising at least one data group; based on the temperature data of each power interval, determining a temperature residual corresponding to each temperature data in each power interval; intercepting the temperature residual error of each power interval based on a preset sliding window to obtain a plurality of residual error segments; determining a Bayesian factor of each residual segment; and evaluating the health state of the wind generating set based on the Bayesian factor of each residual segment.
