Abstract

This paper analyzes the stator flux oriented vector control theory for doubly fed induction generator, control strategy of no-load cutting-in based on grid voltage feedback and control strategy of grid connected based on speed feedback are used in this system, the arithmetic of maximum power point tracking independent of the turbine characteristics and air density is used in this system. The results of the experiments performed on an 100kW test-bed with prototype verified the adopted strategies´ feasibility in system soft cut-in, decoupled control of active and reactive power, as well as the maximum wind power tracking.
