Zusammenfassung:	A method for operating state analysis and early warning of an auxiliary device of a hydroelectric station includes: obtaining start-stop time data of a target auxiliary device of the hydroelectric station and working condition data of a generator unit in a preset time period; determining a plurality of operating time durations and/or a plurality of start-stop time intervals of the target auxiliary device under different working conditions according to the start-stop time data and the working condition data; determining a health value range of the target auxiliary device according to the plurality of operating time durations and/or the plurality of start-stop time intervals; and setting an early warning condition according to the health value range, so as to perform an early warning for a current operating situation of the target auxiliary device. obtaining start-stop time data of a target auxiliary device of the hydroelectric station and working condition data of a generator S101 unit in a preset time period determining a plurality of operating time durations and/or a plurality of start-stop time intervals of the target auxiliary device under different working conditions according to the start-stop time data and the working condition data determining a health value range of the target auxiliary device S103 according to the plurality of operating time durations and/or the plurality of start-stop time intervals setting an early warning condition according to the health value range, so as to perform an early warning for a current operating S104 situation of the target auxiliary device distinguishin operating time duration generating data derived from operating rule of arstatefrom governor oil pump: dafptn mn shtdfown 1) operating time duration under power state quantity of -7generation state governor oil pump at 2) operating time duration under a testing point for. shutdown state operatmng start-3) start-stop time interval under power start-stoptime generationstate interval 4) start-stop time interval under shutdown state --- 1 health threshold state early warning model of automatic mining governor oil pump based on algorithm stat ealy arnig sste ofhealth threshold governor oil pump based on health threshold of state of governor oil pump health thresholdI
