Embodiment Construction
[0027] First of all, it needs to be explained that for synchronous generators, especially the self-shunt excitation system, the excitation voltage of the generator is output by the excitation regulator, which is input to the rotor circuit of the generator for excitation, and the output voltage of the generator is output by the stator .
[0028] see figure 1 , the measuring method of synchronous generator stator open-circuit transient time constant of the present invention, comprises the steps:
[0029] First, let the synchronous generator under test run under no-load conditions, adjust the output voltage of the synchronous generator to be less than the rated output voltage of the synchronous generator, and make the excitation regulator run in the automatic channel. In order to obtain better measurement results, the output voltage of the synchronous generator is preferably 50% to 70% of the rated output voltage of the synchronous generator. This is because, when the voltage of...
