Embodiment Construction

[0026] Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect. In addition, the term "coupled" includes any direct and indirect electrical connection means. Therefore, if it is described that a first device is coupled to a second device, it means that the first device may be directly electrical...

Abstract

The invention discloses a wind power field distributed type high-voltage crossing auxiliary system which comprises a series of thyristor switching electric reactor devices, wherein the devices are mounted between a wind generating set and a transformer, and each of the devices comprises a controller module, a switcher module and an electric reactor. The system provided by the invention increases the high-voltage crossing capacity of the wind generating set; the fan snap-off caused by high voltage is effectively prevented; the high-voltage crossing of the wind field is realized; and the voltage of an integration site is effectively controlled and stabilized in an allowed range.

Description

technical field [0001] The invention relates to the field of wind farms, in particular to a distributed high-voltage ride-through auxiliary system for wind farms. Background technique [0002] As a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world. Its reserves are huge, almost 10 times larger than the total amount of water energy that can be developed and utilized on the earth. At present, the energy obtained by burning coal in the world every year is only one-third of the energy provided by wind power in a year. Therefore, many countries in the world have built large-scale wind turbines to make full use of wind power to generate electricity and develop new energy sources. A power generation network composed of a large number of wind turbines, but with the increasing installed capacity of wind power and the expansion of wind farms, it is becoming more and more difficult to connect to the grid, and the incidence of...
