A multi-module wind farm can fully power individual residences and agricultural facilities that are disconnected from the unified energy system.

On Wednesday, October 13, it became known that the Institute of Energy, Saratov Gagarin State Technical University (SGTU), has designed and experimentally studied an innovative multi-module wind power plant capable of producing an adjustable output electric voltage.

The scientists are confident that this autonomous system for generating cheap and environmentally friendly energy can be produced on a mass scale, the university’s press service reports. The technical solutions underlying the development are protected by ten patents for inventions.

“The approach we have developed allows us to promptly solve the problem of autonomous power supply of small power facilities located at a significant distance from the power system. The project involves installing the required number of modules, summing up the energy flows by power electronics devices, and ensuring the quality of electricity at consumers in the unstable nature of wind energy,” said Professor Ivan Artyukhov of the Department of Electric Power and Electrical Engineering, SSTU.

The unit contains at least three removable modules attached to a rotating frame. The structure also includes a wind direction and speed sensor, and a control unit for the rotating frame. Each module contains a wind wheel with an electric generator and a frequency converter of electric current.

Let us remind that the experts of the Green Energy Scientific-Technical Center, together with the students of the Institute of Energy of Academician Millionshchikov Grozny State Petroleum Technical University installed a network solar power plant with a capacity of 15 kW in one of the educational buildings of the university on an area of 100 square meters. The specialists calculated that in the climate conditions of the capital of the Chechen Republic, the station will be able to produce an average of 63.9 kilowatt-hours of electricity per day.
