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

The rapid development of wind power puts forward higher requirements on the simulation of wind turbine generator dynamic characteristics. Based on the Wind Turbine (WT) and Wind Turbine Induction Generator (WTIG) models contained in MATLAB/Simulink, this paper constructs the corresponding fixed-speed WTIG 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 WTIG 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 WTIG model contained in other simulation platforms (e.g. MATLAB), but also provide more degrees of freedom and more detailed information about state variables in real time.
