| Abstract: | In allusion to the problem which MPPT control strategy of variable speed wind turbine is largely dependent on the machine′s parameters,a dynamic power curve control strategy of maximum power point tracking(MPPT) was presented.This strategy adjusts the proportion coefficient of the power curve according to the current operational states of wind turbine to realize the control of MPPT.The merit of this strategy is less dependent on the machine′s parameters and can still realize the MPPT control even when the measured rotor speed exists errors.Finally,designed the system of the dynamic power curve control strategy of MPPT based on fuzzy control with Matlab/Simulink tool.Simulation results confirm the validity and feasibility of this strategy. |
