Abstract
In order to timely and accurately diagnose the problem of abnormal current attenuation in solar array of LEO(low earth orbit)satellite,a detection method is proposed to effectively identify and detect faults.First,the factors affecting solar array current are analyzed such as ef-fective solar intensity,temperature,task and data quality.Then,the influences of effective solar irradiance and temperature environment are treated as error terms,and the factors affecting the task and data quality are processed through filtering or data restoration.Finally,the abnormal current attenuation is identified by comparing the average maximum current of the solar array ev-ery day.The method verification is carried out using actual satellite telemetry data,and the re-sults show that the diagnostic accuracy of the detection method is higher than 1.5%,which can timely and accurately detect fault caused by abnormal current attenuation in solar array of LEO satellite.关键词
