Abstract

The invention provides a wind-power energy conversion system with redundant energy storage, and an application mode and a control method thereof. The system comprises a hub, a variable pitch system, blades, a base, a generator, a converter, a redundant energy storage battery, a yaw system and a tower frame, and is characterized in that three blades are arranged on the hub, and the variable pitch system is arranged in the hub and is connected with the blades; the top of the tower frame is connected with the base through the yaw system, and the generator on the base is connected with the hub; and the generator is further connected with the converter and the redundant energy storage battery. The wind-power energy conversion system with redundant energy storage, provided by the invention, has the advantages of high energy density, small floor space, high efficiency, short construction period and strong site applicability.

Description

technical field [0001] The invention relates to a wind power energy conversion system with redundant energy storage, which is suitable for large-scale centralized grid-connected wind farms and distributed power generation systems in smart power (micro) grids, especially for small grid capacity or wind power installed capacity Areas that account for a large proportion of the total installed capacity of the grid. It is mainly used to improve the reliability and power quality of wind power energy conversion system, and solve the grid instability problems caused by intermittent, fluctuating and poor predictability of wind power output. Background technique [0002] With the continuous growth of social energy demand and the increasingly prominent environmental problems, seeking a sustainable social development model and making full use of renewable energy have become the key tasks of governments. [0003] Wind energy will occupy an extremely important position in the future ener...
