Multilevel WARD equivalent modeling method for three-level SVG based on L/C constant admittance switch model

The text discusses a multilevel WARD equivalent modeling method for three-level SVG. Aiming at the problem of extremely slow simulation speed in simulation platforms such as PSCAD/EMTDC and MATLAB, a multi-level nested fast algorithm equivalent three-level SVG electromagnetic transient simulation acceleration model is proposed based on the Norton equivalent circuit of the device. Based on the C++programming language, a three-level SVG equivalent model is established. The comparison with the detailed model simulation results of PSCAD shows that the equivalent model has high simulation accuracy and simulation acceleration ratio.
