摘要
Abstract
The operation principle of doubly-fed wind power generation system was introduced,dual PWM converter was adopted as DFIG excitation power supply and its control strategy was discussed in detail, then the simulation model of rotor-side controller and grid-side controller was established based on S-function . The simulation results demonstrate that the model realizes the maximum wind energy tracking , decoupling control of active and reactive power .variable-speed constant-frequency(VSCF) .ensures the stability of the DC voltage while working state switching and the high power factor operation . At the same time,the simulation confirms the correctness of the model and the control strategy.
