Abstract

The invention discloses an electric heat storage integrated wind turbine system and a working method thereof, and belongs to the technical field of wind power generation. The system comprises a wind wheel system, a low-speed shaft, a gear transmission system, a first high-speed shaft, a second high-speed shaft, an electric generator unit and a heat pump unit. The wind wheel system is connected with the input end of the gear transmission system through the low-speed shaft, and two output ends of the gear transmission system are connected with the first high-speed shaft and the second high-speed shaft respectively. The first high-speed shaft is connected with the electric generator unit, the electric generator unit is connected to a power regulation unit, and the power regulation unit is connected with a power grid and an energy storage system. The second high-speed shaft is connected with the heat pump unit, and the heat pump unit is connected to a heat user. By means of the electric heat storage integrated wind turbine system and the working method thereof, on one hand, various energy requirements of electricity, heat and the like are met at the same time; and on the other hand, the benefits of a wind turbine are utilized to the maximum extent, integration of the multiple functions such as power supply, heating and energy storage is achieved, waste of a large amount of energy of the wind turbine caused by the factors such as power limitation of the power grid is avoided, and the economic benefits of the wind turbine are increased.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a wind turbine system with integrated electric heat storage and a working method thereof. Background technique [0002] Wind turbines are a low-carbon, near-zero-emission form of power generation that convert wind energy into electricity to provide clean, renewable electricity to the grid. At the same time, it can also be used for heating, that is, wind energy is used as the driving force, and wind energy is directly converted into heat energy without going through the power generation link. Due to the reduction of the energy conversion loss of wind energy and electric energy, the air heat unit reduces the system cost and greatly improves the system efficiency. The economic indicators are far superior to the current mainstream clean energy heating / cooling technology. [0003] At present, most of the wind turbines are only used as wind turbines for power...
