This paper presents the dynamic behavior simulation of a multimachine wind power system operating in normal and abnormal situations. The system primarily consisted of four fixed-speed and active pitch-controlled wind turbines, and other electrical components. The mathematical models for the components, developed to cater for the dynamic behavior of the system using Power System Blockset, included wind model, electric machine model, electromechanical model, three-phase power transformer model, and capacitor bank model. Simulation results showed that the system operated satisfactorily in sequentially starting and three-phase balanced fault situations. The dynamic behavior study for a wind power system is essential for planning and operation.
