Wind Turbine Generator System

In order to maintain the stable operation of grid system, the grid company requires wind turbine generator system with low-voltage ride through (LVRT) capability. With this issue, the article builds a double-fed wind turbine generator system model, Crowbar circuit strategy model to protect rotor-side inverter and fault pitch control strategy model to inhibition rotor speed during grid fault. Then all the models and strategies are verified by the simulation of grid low voltage. The simulation results show that these models can complete LVRT.

Servo Drive System

This paper firstly analyzed the theory of the MW wind turbine generator pitch control, and then based on the analysis, designed a servo drive system with PMSM motor-driven and double closed loop control consisted of inner speed loop and outer current loop. Finally, use MATLAB establishes the corresponding model to simulation test. Simulation results show that the servo control system has good dynamic, steady state performance and robustness.
