Power supply and detection system for underground generator

The invention relates to an underground generator power supply and detection system which comprises an underground generator, a three-phase bridge rectifier module, a bus, a DSP processing module and a generator control module. Wherein the underground generator is respectively connected with the three-phase bridge rectifier module and the generator control module, the three-phase bridge rectifier module is connected with the bus, the bus is connected with the DSP processing module, and the DSP processing module is connected with the generator control module. When the voltage of the underground generator is too high, voltage regulation of the underground generator is completed once every preset time, the purpose of linearly regulating the voltage is achieved, in addition, the duration of each time of voltage regulation is determined according to the deviation and the change rate of the deviation, and the accuracy of voltage regulation is improved. 本发明涉及一种井下发电机供电及检测系统，包括：井下发电机、三相桥式整流模块、母线、DSP处理模块和发电机控制模块；其中，井下发
