Stabilization of the rotor speed of an asynchronous generator of a wind power plant

Abstract

Alternative energy sources play a significant part in the development of modern electric power, agriculture and forestry. In accordance with the decree of the Government of the Russian Federation of 08.01.2009 1-p "On the main directions of state policy in the field of improving the energy efficiency of the electric power industry based on the use of renewable energy sources for the period up to 2035", currently, due to the high level of environmental pollution, the use of electricity obtained using alternative sources is relevant. Since alternative energy sources are renewable, there is no need for additional raw materials that are needed to generate energy. Alternative sources of electricity are widely used for consumers who are located in a remote area from power lines and have the need to obtain not only single-phase, but also three-phase electrical energy. For the implementation of power supply to these consumers, a wind turbine is considered, which allows for long-term uninterrupted three-phase power supply. The main difference of this wind turbine is a device for stabilizing the rotor speed of an asynchronous generator, which is a combined synchronous machine with a common inductor.
