Autonomous wind power plant with aerodynamic multiplication based on asynchronous generator with a phase rotor with excitation from a voltage-source inverter

The article analyzes the methods of increasing the efficiency of converting wind energy into electricity in wind power plants. It is noted that there are both aero-mechanical and electrical methods of increasing the efficiency of converting wind energy into electricity. Multiplierless schemes that allow to increase the efficiency of aero-mechanical conversion of wind energy are considered. These include the use of low-speed generators and aerodynamic multiplication. Aerodynamic multiplication is considered promising and more acceptable for high-power autonomous wind power plants, considering that low-speed generators have poor mass-dimensional indicators. Historical information on the development of systems with aerodynamic multiplication is given. Similar systems are currently being developed only in Ukraine, where the experimental operation and implementation of the TG-750 industrial model have been carried out, and in the United Kingdom. The perspective of using systems with incomplete energy conversion has been revealed. The improvement of indicators is determined by the use of a slip power converter of an asynchronous generator with a phase rotor and a voltage-source inverter. A new structure of an autonomous wind power plant with aerodynamic multiplication based on an asynchronous generator with a phase rotor with excitation from a voltage-source inverter is proposed. Information on the operation of the system is provided. The use of a voltage-source inverter allows you to abandon an additional source of alternating voltage for an asynchronous generator with a phase rotor and provide the system with the features of an uninterrupted power source. The considered structure of the autonomous wind power plant is presented in the utility model application.
