Embodiment Construction
[0055] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0056] The specific steps of this algorithm are as follows:
[0057] Step 1) Construct the relevant atomic library, and serialize the atom discretization parameters, the specific content is:
[0058] Step 11) The fundamental wave is the main component of the sudden short-circuit current. In order to accurately analyze the parameters of the synchronous motor, it is necessary to extract the fundamental wave component and construct the fundamental wave atomic library In the formula:
[0059] f 1 is the fundamental frequency, is the fundamental phase, t s1 Indicates the start time of the fundamental wave, t e1 Indicates the end moment of the fundamental wave; u(t) is the unit step function...
