Multi-stage wind turbine with adaptive wind speed and its control method

Abstract

The invention discloses a multistage wind driven generator self-adaptive to wind speed and a control method thereof. The multistage wind driven generator comprises a wind power sensor, a microprocessor and a wind driven generator set, wherein the wind power sensor is used for acquiring wind speed signals of a wind field in real time and sending the acquired data to the microprocessor, the microprocessor receives the wind speed data acquired by the wind power sensor, determines the length of blades and selects corresponding wind speed models of generators according to the acquired wind speed data and sends corresponding instructions to an execution mechanism and a driving module of the wind driven generator set, and the execution mechanism and the driving module of the wind driven generator set adjust extension of the blades of the wind driven generator set and select the corresponding wind speed models of generators to work together according to the instructions from the microprocessor. The multistage wind driven generator self-adaptive to wind speed is capable of making adjustment and using the wind driven generator of a corresponding wind stage to work according to the actual wind speed, and the power supply reliability and maximum wind energy utilization of the wind driven generator are improved.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to a wind speed adaptive multi-stage wind power generator and a control method thereof. Background technique [0002] At present, the existing wind power generators all have a fixed output wattage range, and the output range is generally not adjustable. That is to say, the existing wind power generator has fixed blade size, the generator works under fixed rated parameters, and the generator has only two stages. Once the wind turbine is installed, all parameters will not be variable, and once the range of wind speed changes is expanded, the wind turbine will not work normally. [0003] As we all know, the wind speed has seasonality and weather characteristics. Since the existing wind generators can only work under rated wind speed conditions, the wind generators will not work normally in seasons with low wind speeds or in weather with low wind speeds, which will greatly Affect ...

[0003] As we all know, the wind speed has seasonality and weather characteristics. Since the existing wind generators can only work under rated wind speed conditions, the wind generators will not work normally in seasons with low wind speeds or in weather with low wind speeds, which will greatly Affect the normal power supply of wind turbines
