Conceptual Design and Simulation of a Novel Speed Self-stabilizing Mechanism

A speed stabilizing mechanism was introduced for outputing constant frequency current of wind turbine. The traditional feedback adjusting speed stabilizing mechanism and the novel speed self-stabilizing mechanism were contrasted and analyzed from the angle of the kinematics principle. The Simulink models of wind power system with different speed stabilizing mechanisms were built. The time varing speed of wind rotor simulated by FAST software served as the inputs of the model. Two kinds of speed stabilizing mechanisms worked under the same input conditions. The simulation results show that the quality of steady speed from novel speed self-stabilizing mechanism is better than that from traditional feedback adjusting speed stabilizing mechanism.
