Method for improving running efficiency of fan during icing period of wind power plant

Abstract

The invention belongs to the technical field of wind power generation, and discloses a method for improving running efficiency of a fan during an icing period of a wind power plant. The method comprises the steps of: acquiring an icing position through an image acquisition module and an icing detection module, and melting the ice through an ice melting module; detecting the fan and the environment around the fan through an environment detection module and a fan running detection module, and acquiring corresponding data; acquiring installation coordinates and technical parameters of existing large fans of the wind power plant, arranging small fans among the large fans in the wind power plant according to an icing condition, wherein the small fans are arranged at positions set in a scheme to form various small fan installation schemes; solving out an output gain of the wind power plant under various small fan additional installation schemes; and determining a scheme for constructing an observation base and improving the running efficiency of the fan according to the acquired data. The method provided by the invention guarantees an effect of the engineering, improves the practicability, saves labor and materials and improves the power generation efficiency of the wind power plant by additionally arranging small fans.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a method for improving the operating efficiency of wind turbines during the ice-covering period of a wind farm. Background technique [0002] At present, due to the aggravation and deterioration of the international energy crisis and environmental problems, wind power is leading to get rid of the dependence on fossil fuels. At present, wind farms mainly adopt the single-machine maximum wind energy capture scheme to improve power generation efficiency. However, depending on the region, in winter The icing situation of each wind farm is different. The icing situation will appear on the wind turbine on the wire. Once it is covered with ice, it will greatly reduce the power generation efficiency of the power plant, resulting in slow power generation or other dangerous problems. The current existing technology There is no way to alleviate the icing of wind fa...

AI Technical Summary

Problems solved by technology

[0002] At present, due to the aggravation and deterioration of the international energy crisis and environmental problems, wind power is leading to get rid of the dependence on fossil fuels. The maximum wind energy capture scheme for a single machine, but depending on the region, the icing situation of each wind farm in winter is different, and the icing situation will appear on the wind turbine on the wire. Once it is covered with ice, the power generation efficiency of the power plant will be greatly reduced. , resulting in slow power generation or other dangerous problems. At present, the existing technology does not alleviate the icing situation of wind farms, and there is no method for observing the icing situation of wires. In winter, especially in alpine wind farms, the icing situation It is very common, and once it occurs, there is no way to alleviate it, which will cause a large area of ​​paralysis of the surrounding fans

[0003]Through the above analysis, the problems and defects of the existing technology are: the existing technology does not alleviate the icing situation of the wind farm, nor does it icing the wires The method of observing the situation, once the icing situation occurs, can only wait for the icing to dissipate on its own
