[0014] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings of the specification.
[0015] Such as figure 1 As shown, the synchronous tracking method of the generator excitation device disclosed in the present invention for the actual measured speed and the calculated speed is implemented according to the following steps:
[0016] Step 1: Preprocess the historical data of the calculated rotational speed and measured rotational speed of the generator rotor as the training sample and test sample of the support vector machine model;
[0017] 1.1 Calculate the generator rotor speed; this invention uses the traditional method to calculate the generator calculation speed: the traditional generator excitation device calculates the electromagnetic power based on the terminal voltage and the stator current (three-meter method or two-meter method, depending on whether the device analog quantity acquisition channe...
