Problems solved by technology
The electromechanical transient model is to simplify the wind farm part. Since the electromechanical transient model is based on the fundamental wave, single-phase, and phasor models, it cannot reflect the large number of insulated gate bipolar transistors (insulated gate bipolar transistors, The dynamic process of power electronic devices such as IGBT) cannot meet the simulation accuracy requirements of actual engineering, so wind farms generally use electromagnetic transient modeling
The existing electromagnetic transient simulation software is widely used, including Matlab / Simulink, PSCAD / EMTDC, RTDS and ADPSS, among which Matlab / Simulink and PSCAD / EMTDC simulation platforms do not have real-time performance, while RTDS is a foreign simulation platform, and there are technical barrier
