Abstract
Wind and solar power plants for autonomous power supply of small oil and gas facilities with a capacity of no more than 20 kW, wind power plants in their composition – 10 kW with a power factor (energy efficiency) of no more than 0.35–0.45 are considered. An improved design of an orbital wind power plant based on a combined H-Darye-Savonius rotor has been developed. Experiments on the laboratory installation showed that the maximum values of the power factor reached 0.60, which is much higher than that of the rotors of known types of wind turbines. The values of the CRDS power factor are calculated for various geometric dimensions of the N-Darye and Savonius rotors included in its composition. With an increase in wind speed to the nominal value of 9.0 m/s for small and medium power wind turbines and a rotor diameter of 15.0 m, the combined rotor power reaches almost 60 kW. The proposed orthogonal wind power plants with a nominal capacity of up to 60 kW will be able to be used together with other power plants for autonomous power supply at oil and gas field facilities on land and at sea, and in the future at intelligent fields.
