Comparative Simulation of Dynamic Characteristics of Wind Turbine Doubly-Fed Induction Generator Based on RTDS and MATLAB

摘要

The rapid development of wind power puts forward higher requirements on the simulation of wind turbine generator dynamic characteristics. Based on the Wind Turbine Doubly-Fed Induction Generator (WTDFIG) average model contained in MATLAB/Simulink, this paper constructs the corresponding variable-speed WTDFIG average model on RTDS/RSCAD platform firstly. Secondly, the simulation methods adopted by MATLAB and RTDS respectively are compared. Thirdly, based on a constructed One-Machine-Infinite-Bus (OMIB) system, a comparative validation of initial value, dynamic response of WTDFIG under wind and fault disturbance is made between MATLAB and RTDS platforms. The simulation results show that, RTDS can not only accurately implement and validate the WTDFIG model contained in other simulation platforms (e.g. MATLAB), but also provide more detailed information about state variables in real time.
