Embodiment Construction
[0020] The present invention is described with reference to the drawings and specific embodiments.
[0021] Such as figure 1 As shown in Fig. 1, a starting method of a generator reversely driving a high-power diesel engine. The generator set adopts a combination of a diesel engine and an asynchronous generator. Convert the voltage of the external high-voltage AC power supply 1 into the rated voltage of the variable-speed and variable-speed generator set 2, and send power to the variable-frequency and variable-speed generator set; at the same time, the inverter III 2 activates the control box 4 of the generator set and sends out an electric start command for the generator set. The generator runs in the state of electric start, starts to rotate and reversely drives the diesel engine to rotate through the disc coupling or high-elastic coupling, when the diesel engine speed reaches the set speed, the generator set control system instructs the injector to inject fuel, and the diese...
