Embodiment Construction
[0017] The principles of the present invention will be described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0018] The invention provides a method for reducing consumption of a wind power generating set, comprising:
[0019] Determine whether the operating condition of the unit is power generation or shutdown.
[0020] The consumption reduction method when the unit is in the power generation state includes the control logic of waiting for the wind to stop. Such as 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 is enabled=1, the wind speed within a certain time T in the future is predicted, and when the predicted wind speed is lower than the start-up wind speed, it is delayed for a period of ti...

The invention provides a method for reducing the consumption of a wind power generating set. The judgment of the operating condition of the generating set is used as the judgment condition of the control logic of the wind generating set for reducing the consumption. The wind direction is added to the yaw strategy of the wind turbine, and the intermittent operation mode and pressure control mode of the gearbox oil pump are started on demand under different operating conditions. Effectively reduce the power consumption more than the power generation during frequent start-up and stop, increase the power generation of the wind turbine as a whole, reduce the mechanical and electrical consumption of key components of the wind turbine; facilitate the unit to quickly enter the power generation state after the future wind speed meets the start-up conditions; reduce The power consumption loss and unnecessary mechanical wear of the gearbox itself.
Description
technical field [0001] The invention relates to control strategies for wind power generators. Background technique [0002] The main goal of wind farm operation and management is to increase power generation and benefit. Increasing revenue and reducing expenditure are the main means to increase the profit of the farm. Reducing the power consumption rate of the comprehensive plant and fan consumables has certain economic value for improving the production efficiency of the farm. And with the gradual increase in the capacity of a single wind turbine unit, the self-consumption power and consumables of the wind turbine itself are also gradually increased. Since the wind turbine self-consumption and consumables are inevitable losses of wind power generation, the self-consumption and consumables themselves can only be reduced but not eliminated, reducing the self-consumption of wind turbines and the consumption of consumables to achieve the purpose of improving the operating econo...
