Dynamic power control system of variable speed constant frequency doubly-fed asynchronous wind-driven generator

The invention relates to a dynamic power control system of a variable speed constant frequency doubly-fed asynchronous wind-driven generator. The dynamic power control system comprises a doubly-fed generator and is characterized in that the power control system contains a control unit, a PWM pulse generation unit, a converter and a detection unit. The dynamic power control system has the advantage that 1) the flexible grid connection is beneficial to realize; 2) the active power and reactive power of the generator can be independently regulated; 3) the capacity of the converter is reduced so as to reduce the cost of the converter; 4) the wind energy can be fully used; 5) the optimization of power control can be reached; and 6) the information fusion algorithm is easy to carry out without sacrificing the real-time property.
