Description

Technical Field

[0001] The utility model relates to the technical field of energy storage and conversion, and in particular to a flywheel frequency modulation device. Background Art

[0002] Energy storage is an important support for building a new power system. It changes the traditional model of power system that is used immediately after power generation and production and consumption are completed at the same time. With the continuous increase of new energy installed capacity in my country, the "new energy + energy storage" model has become an effective way to solve the problem of new energy consumption.

[0003] Flywheel energy storage technology is a mechanical energy storage technology that stores energy through a high-speed rotating wheel and converts this energy into mechanical energy or electrical energy output when needed. Compared with traditional battery energy storage technology, flywheel energy storage technology has the advantages of high energy storage efficiency, high output power, and fast response speed. Therefore, it is widely used in power grid frequency regulation, automotive power systems and other fields.

[0004] The flywheel energy storage frequency regulation principle is to achieve the purpose of grid regulation by controlling the flywheel speed and output power. When the grid load increases, the frequency regulation system will sense this change and increase the speed of the flywheel system to store more mechanical energy. When the grid load decreases, the frequency regulation system will sense this change, reduce the speed of the flywheel system, and convert the mechanical energy stored in the flywheel system into electrical energy output. During the grid regulation process, the frequency regulation system continuously adjusts the speed of the flywheel system to achieve a balance between grid load and power generation, thereby maintaining the stability of the grid. The flywheel energy storage frequency regulation principle is an efficient and reliable grid regulation technology with the characteristics of fast response, high energy storage efficiency, and large output power.

[0005] However, when the huge and heavy flywheel rotates at high speed, it will generate huge centrifugal force. Although there is no risk of combustion and explosion, there is a safety hazard of the flywheel falling off, which is extremely unsafe and poses a serious threat to surrounding personnel and equipment.
