Embodiment Construction

[0017] The principle of the present invention will be described below with reference to the accompanying drawings, and the examples are only used to explain the present invention, but not to limit the scope of the present invention.

[0018] The present invention provides a method for reducing the consumption of wind turbines, comprising:

[0019] It is judged whether the operating condition of the unit is the power generation state or the shutdown state.

[0020] When the unit is in the power generation state, the consumption reduction method includes the control logic of equal wind shutdown. like figure 1 As shown, when the generated power is less than the off-grid power, the predicted wind speed is used to participate in the control logic, that is, when the predicted wind speed enable = 1, the wind speed within a certain time T in the future is predicted, and when the predicted wind speed is less than the starting wind speed, it will be delayed for a period of time After ...

Abstract

The invention provides a method for reducing consumption of a wind generating set. The method for reducing consumption of the wind generating set comprises the following steps of: taking set operationcondition judgment as a judgment condition of wind generating set consumption reduction control logic, adding a future predicted wind speed into set equal-wind shutdown logic judgment, adding the future predicted wind speed and an unpredicted wind direction into a fan yawing strategy, and under different operation conditions, starting an intermittent operation mode and a pressure control mode ofa gearbox oil pump as required. The power consumption more than the generating capacity in the process of frequent start and stop is effectively reduced, the generating capacity of the wind generatingset is improved on the whole, and the mechanical and electrical consumption of key components of the wind generating set is reduced; after the future wind speed meets the starting condition, the setcan quickly enter the power generation state; and the power consumption loss and unnecessary mechanical wear of a gearbox are reduced.

Description

technical field [0001] The present invention relates to a control strategy for wind turbines. Background technique [0002] The main goal of wind farm operation and management is to generate power and benefit. Opening up and reducing expenditure is the main means to increase the profit of the farm. Reducing the comprehensive power consumption rate and fan consumables has certain economic value for improving the production efficiency of the farm. And with the gradual increase of the single-unit capacity of the wind turbine, the self-consumption power and consumables of the fan itself also gradually increase. Since the fan's self-consumption and consumables are the inevitable losses of fan power generation, the self-consumption and consumables themselves can only be reduced but not eliminated, reducing the fan's self-consumption and the consumption of consumables, and achieving the purpose of improving the operating economy of the wind farm. With the aggravation of the energy...
