| Abstract: | This paper presents a simplified model of wind turbine variable pitch control. The pitch angle is adjusted by the feedback signals of generating speed and the output power of the wind turbine. And it can control generators speed constant and wind turbine output power steady. The variable pitch control is modeled using the simulation software PSCAD/EMTDC. The entire wind power system （including doubly-fed induction generators, converter and so on） is simulated. Results show that the variable pitch control strategy is feasible and correct. |
