Problems of integration of wind power in the unified energy system of Russia
Incoming article date: 03.10.2014The article discusses the innovative technology of increasing energy efficiency of wind power station. Also addresses the issue of stabilization of wind generator power at variable wind velocity. The key idea of research consists in reduce losses in the system of generation (quick-response induction machine) and power conversion (voltage source converter) obtained from the wind turbine. Control system was developed for wind turbine, consisting of two control loops: pitch control and direct torque control. Using of direct torque control system of the quick-response induction machine moment is offered for stabilization of wind generator output power. At the same time, the pitch control of the blades wind turbine used to restrict the allowable range for the generated power. Proposed control system allows to increase the production of the power generated by the wind turbine.
