Title:
METHOD FOR ELECTROMAGNETIC TRANSIENT SIMULATION OF TRANSFORMER, COMPUTER DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/082163
Kind Code:
A1
Abstract:
The present application relates to a method for electromagnetic transient simulation of a transformer. The method comprises: building a transformer model on the basis of a finite-difference time-domain method, and setting the time step of the transformer model; acquiring a frequency response curve of the transformer; updating an electric field component and a magnetic field component of the transformer model on the basis of the frequency response curve to obtain an electric field component of the current time step and a magnetic field component of the current time step; and if the electric field component of the current time step or the magnetic field component of the current time step converges, ending the simulation. According to the present application, the transformer model is established on the basis of the finite-difference time-domain method, without the need of complex and tedious calculation and on-site tests, so that the calculation efficiency can be greatly improved. In addition, the electric field component and the magnetic field component of the transformer model are updated on the basis of the frequency response curve. In this way, electromagnetic response parameters of a frequency-dependent transformer can be taken into full consideration in the time domain, thereby greatly improving simulation precision.
