A power generation system combining wind energy with other energy sources

Abstract

The invention discloses a power generation system adopting wind energy in combination with other types of energy, in particular to a multi-energy complement energy power generation system, and relatesto the technical fields of energy storage systems and multi-energy complement. The system has the advantages that by means of the system, the traditional wind power generation mode is changed, the mode that wind energy is directly transformed into mechanical energy through fans to drive a generator to generate electricity is abandoned, mechanical energy generated by the fans is directly adopted to drive compressors, high-low voltage conversion is achieved through a thermodynamic medium, thus, the wind energy is transformed into thermodynamic energy, after effectively energy storage and balanced output are completed, the thermodynamic medium can be combined with other types of energy, the generator is driven to generate the electricity through transformation of an expansion machine, and compared with the traditional mode that power generation is conducted through the wind energy of the fans, the mode is more stable in power generation; energy storage and balancing are conducted throughthe thermodynamic medium, and other types of renewable energy for generating heat energy can be combined to be used for power generation; and the wind energy is combined with other types of heat energy, and the repeated grid connection cost is lowered. By means of the Bretton closed system, the cost for the traditional thermoelectrical Rankine cycle is lowered.
