[0074] by figure 2 The test result of a 600MW thermal power unit shown as an example further illustrates the present invention in detail, but the present invention is not limited to the given example. figure 2 It is the recorded wave diagram of the ±2% step response test without PSS according to the recorded wave result of the actual test according to the embodiment of the present invention. like figure 2 As shown, UAB and Q are the response curves of generator stator voltage U(t) and reactive power Q(t), respectively. Among them, the generator voltage step start time is 1.8s, the generator voltage step end time is 10.9s, the steady state point generator stator voltage and reactive power before the step can be read within 0s-1.8s, 1.8 The steady-state point generator stator voltage and reactive power after the step can be read within s-10.9s.
[0075] The steps of measuring the generator voltage droop rate according to the embodiment of the present invention are as follo...
