[0022] The present invention will be further described below with reference to the accompanying drawings.
[0023] The present invention obtains the values of several undetermined time constants in the curve fitting function by running and calculating the nonlinear least squares fitting program written in the programming language, obtains the time constant of the phase compensation link of the PSS, and completes the calculation of the time constant of the phase compensation link of the PSS. Calculation, the principle is clear, the calculation is simple, and the compensation effect is better. With the continuous upgrading of computer application software, the algorithm of the nonlinear least squares fitting program is packaged and defined as a corresponding function or tool, which can be called directly when used to make the calculation It becomes easier and more convenient, including the following steps:
[0024] The first step is to list the frequency-phase two-dimensional ...
