Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0027] The vertical axis wind power generation system provided by the present invention includes at least one vertical axis wind power generator, wherein the specific number of wind power generators is set according to the output power of the power generation system or other requirements. Moreover, the vertical-axis wind turbine may be an H-type vertical-axis wind generator, or other types of vertical-axis wind turbines. Since the H-type vertical-axis wind power generator takes into account the advantages of the vertical-axis wind power generator, the design of the gearbox and the generator bearing is mature, and the permanent magnet synchronous motor is used as the generator to solve the problem of self-starting of the fan, so in this embodiment , for the convenience of description, take the H-type vertical axis wind turbine as an example, hereinafter referr...

Abstract

The invention relates to a vertical axis wind power generation system start-up control method and a wind power generation system. When the wind power generation system is started up, a centralized net-connected controller starts net connection and controls various control switches to be off; a machine side controller drags the corresponding vertical axis wind power generator to rotate to the set start-up speed; and the working mode of the vertical axis wind power generator is switched to the power generation mode, thereby carrying out wind power generation. The start-up method can control the vertical axis wind power generator to be effectively started up, thereby solving the problem of difficulty in starting up the vertical axis wind power generator.

Description

technical field [0001] The invention relates to a start-up control method of a vertical axis wind power generation system and a wind power generation system. Background technique [0002] According to the direction of the rotation axis, wind turbines can be divided into two types: horizontal axis and vertical axis. The vertical axis wind turbine has the advantages of low noise, convenient maintenance, simple design and manufacture of blades, low cost, no need for wind-facing devices, and no need for too high towers. When the vertical axis wind rotor becomes larger, it will face the problem of increasing vertical bearing bending moment. The greater the bending moment, the higher the strength of the shaft, which is not only heavy but also easy to damage. Therefore, the commercialization of high-power vertical-axis fans is limited. At present, vertical-axis fans are generally widely used in the field of small-power fans, and there is a problem that the vertical-axis fans cann...
