Fan power generation system with function of storing gravitational potential energy and control method thereof

Abstract

The invention discloses a fan power generation system with the function of storing gravitational potential energy. A wind energy tower is installed on the ground, a fan cabin is installed at the top of the wind energy tower, a wind energy shaft is fixed in the fan cabin, the wind energy shaft is connected with fan blades outside the fan cabin, the wind energy shaft is connected with the input endof a wind power conversion clutch machine, and the two output ends of the wind power conversion clutch machine are connected with a one-way transmission shaft F and a one-way transmission shaft C respectively. The fan power generation system has the advantages that the kinetic energy of wind can be collected by using the wind blades, meanwhile, the residual electric energy obtained at the load peak of an electric power system or the electric energy obtained through other modes are converted into mechanical kinetic energy, wherein a gravity body is lifted to the upper end of the wind energy tower or the relatively high position of other structural bodies, so that the wind energy or electric energy which cannot be stored is converted into the gravitational potential energy which can be stored of the gravity body, and the fan power generation system is provided with a wind power storage gravitational potential energy power generation system which can realize synchronous operation of energy storage and power generation.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to a wind power storage gravitational potential energy generation system capable of synchronous operation of energy storage and power generation. Background technique [0002] There are always peaks and troughs in the use of electric energy. Often, the supply of electric energy is insufficient during the peak period, and there is excess electric energy during the trough period. None of the existing power generation methods can avoid such problems. Although it can be dispatched through the power grid, it is inevitable to waste energy in new energy power generation by abandoning wind, light, and electricity. Green energy such as wind energy and solar energy are greatly affected by meteorological conditions and cannot provide a continuous source of power. There may not be wind or sun during peak power consumption. Moreover, in traditional wind power generation, the power grid can...
