Multi-unit modular wind farm for areas of low wind potential

Abstract

Many dispersed sites are remote from the power grid in agriculture. The centralized power supply of these objects with electric energy from the power grid is unprofitable. During the year, tests were conducted in full-scale conditions of wind power plants with different parameters under conditions of power shortage. The article proposes the development of a multi-unit wind power plant with an additive block, where the energy from multiple winds receiving devices is summed. The article shows that the wind turbine operates in a stable mode in an extended range of wind speeds of 4500 hours per year and generates rated power even in conditions of power shortage due to energy storage and operation of the wind turbines with different parameters. It is two times longer than the power of the wind turbine with separate generators during the year. Studies have shown that at low wind speeds of 4-5 m/s, a 1 kW wind power plant generates up to 840 W at wind speeds of 4-6 m/s, the efficiency of a multi-unit wind power plant is 4 times higher than the overall efficiency of individual wind power plants operating on their own generators.
