This paper presents a method for controlling the output power of a permanent magnet synchronous generator (PMSG) in strong wind conditions. Currently, most of wind turbines are stopped and disconnected from the power system when wind speeds reaches more then 25 m/s. This will lead to detrimental power and voltage fluctuations in the power system. To overcome this problem, output power, pitch angle and rotation speed command values are designated. A novel method, which includes pitch angle and rotation speed control is proposed. Simulation results show that the wind turbine can generate stable power during strong wind conditions. |
