Embodiment Construction

[0038] Below in conjunction with accompanying drawing, the present invention will be further described by embodiment:

[0039] attached Image 6 It is the control schematic diagram of the present invention adopting the doubly-fed motor as the generator. In the figure, the speed and torque parameters (including speed parameters) of the low-speed shaft measured by the main controller according to the parameters, the wind direction and wind speed parameters of the environment, the pitch parameters, the electrical parameters such as the power of the main generator, and the power of the auxiliary generator And other electrical parameters, etc., to control the braking of each brake and the adjustment of the pitch. The present invention can be controlled by the program to work in the following states:

[0040] 1) In the working state of extremely low wind speed (light wind), that is, the shaft of the main generator is braked (the main generator is not working, the same below), the ...

Abstract

The invention provides a wind generating set enabling power to be distributed intelligently and relates to the field of wind power generation. Two or more than two independent generators are adopted in the wind generating set, a planetary gear system is utilized to be matched with a brake and a clutch so as to serve as a power distribution device, power distribution is controlled intelligently according to measured data through a measurement and control circuit, and therefore wind energy can be used more reasonably and more efficiently. The wind generating set is wide in wind speed application range, can improve the utilization efficiency of the wind energy, can run in an all-weather mode (can be adapted to various wind speed environments and increase effective running time), and can make full use of the strong wind energy in the high-speed strong wind environment, thereby increasing on-grid energy greatly, improving economic benefit, and greatly shortening investment payoff period. The wind generating set is simple in structure, low in investment cost increase and capable of improving earnings greatly.

Description

technical field [0001] The present invention relates to the field of wind power generation, and at the same time relates to "electromechanical equipment with sensors" and "a coaxial elastic transmission" and the application of patented technologies. [0002] "Mechanical and electrical equipment with built-in torque sensor" is a patented technology in the National Patent Office with application numbers: 201220489310.0 (authorized) and 201210357726.1. "A Coaxial Elastic Transmission Pad" is a patented technology with application numbers in the National Patent Office: 201210343959.6, 201220473048.0 (authorized). Background technique [0003] As a renewable energy source, wind energy has received widespread attention. Because wind energy in nature is extremely unstable (mainly wind speed is unstable), it is difficult for people to fully and efficiently utilize wind energy. Even though the current electromechanical manufacturing technology and control technology have reached a ...
