Abstract

The invention provides a fan tower drum provided with an energy storage device and a power grid operation method. The fan tower drum provided with the energy storage device is characterized by comprising a wind wheel, a tower drum body, blades, a cabin, a gear box in the cabin, a main shaft, a generator, a power transmission line, a power supply system, energy storage devices and a connection power transmission line, the energy storage devices are arranged in the fan tower drum body in a layered mode and used for storing electric energy converted by power energy; and the energy storage devices are connected with a wind driven generator, the power supply system and an external transmission line through the power transmission line. The energy storage devices with a certain capacity are arranged in the space in the fan tower drum body, the space utilization rate is greatly increased, and the cost of power transmission lines and site civil engineering is reduced.

Description

technical field [0001] The invention relates to the field of wind power generation, more specifically, to a wind turbine tower provided with an energy storage device and an energy storage method. Background technique [0002] In order to cope with global climate change and improve my country's energy structure, wind power has been vigorously promoted as an emerging renewable energy. With the advancement of technology and the improvement of manufacturing capacity, the scale of wind power construction in my country has gradually expanded. In 2013, the installed capacity of wind power generators exceeded 75 million kilowatts, and the total installed capacity is planned to reach 200 million kilowatts in 2020. The rapid development of wind power is facing many challenges, among which the problem that wind power output is limited by system operating conditions has become increasingly prominent, mainly because the randomness and intermittency of wind speed make the output of wind p...
