Repetitive pulse parameter optimization method and device for generator rotor turn-to-turn short circuit diagnosis

The invention discloses a repetitive pulse parameter optimization method and device for turn-to-turn short circuit diagnosis of a generator rotor, and the method comprises the steps: optimizing one ormore of a first parameter, a second parameter, a third parameter, a fourth parameter, a fifth parameter and a sixth parameter of a repetitive pulse, wherein the first parameter is the time for the pulse to rise from a 10% peak value to a 90% peak value, the second parameter is the maximum value of the pulse, the third parameter is the time for the pulse to fall from the maximum value to a zero value, the fourth parameter is the pulse width of the rectangular pulse, the fifth parameter is the pulse repetition period of the steep pulse, and the sixth parameter is the pulse repetition period ofthe rectangular pulse. According to the invention, the matching degree of the repetitive pulse and the target rotor is improved, the fault diagnosis sensitivity is improved, the fault detection rate is ensured, and the optimal
