Simulations of a Commercial Wind Power Generation System with Four Wind-Turbine Induction Generators

This paper analyzes both dynamic and steady-state characteristics of a commercial wind power generation system (WPGS) containing four wind-turbine induction generators (WTIGs) connected to a utility grid using Matlab/Simulink. The simulated power-flow results are validated by comparing with the field measured results of the studied WPGS. Various steady-state results of the studied WPGS under different configurations, cable conditions, and rotor resistances are performed. Dynamic simulations of the studied four WTIG under unbalanced and balanced faulted conditions are also examined. Dynamic characteristics of one WTIG with and without a static VAR compensator (SVC) connected to WTIG´s terminal for voltage support are also compared. It can be concluded from the simulated results that the proposed models can be effectively employed for both steady-state and dynamic simulations of the practical commercial WPGS under various operating conditions and disturbance conditions.
