| Wind energy is a rapid development renewable energy in recent years,.Wind energy conversion system is one of the mainstream technology which is still to be completed A control objective of wind power generation system s is to achieve the maximum power capture of wind energy.Based on the analysis of the conventional MPPT control method of wind power system,this paper proposes a new MPPT control method for wind power system.The input variable of the control method is the output power of the motor stator side and the rotor speed of the generator,and the output is the optimal value of the rotor speed of the generator,which can ensure that the system can still run in the best position when the power curve is not given in detail.Conventional control methods need to measure the wind speed,obtain the fan model and parameters,calculate the po wer and speed differential and have other shortcomings.The simulation results show its effectiveness. |
