[0030] This embodiment provides a wind farm active power control method, please refer to Figure 2, figure 2 A flow chart of the method for controlling the active power of a wind farm provided by this embodiment is shown. It should be noted that the wind farm active power control method provided in this embodiment can be applied to a wind farm active power control device.
[0031] The control method provided in this embodiment includes step S10 to step S60.
[0032] Step S10: Generate dynamic power curves of each wind turbine based on the real-time wind speed of the wind farm and the actual output power of the wind turbine.
[0033] In the normal operation state of the unit, according to the principle of mathematical statistics, based on the relationship between the real-time wind speed and the actual output power of the wind farm, the power curve of each unit is drawn. During the operation of the wind farm, the power curve is dynamically corrected in real time, and the dyna...

Abstract
The invention relates to the field of wind power, and provides a wind farm active power control method, device and electronic equipment, which can better reflect the power characteristics of the unit in the dynamic process by updating the dynamic power curve of the unit in real time. When the power curve of individual units deviates greatly from the original power curve due to control algorithm, yaw accuracy, or differences in mechanical parameters, etc., the cause can be checked to facilitate the optimal operation of the units; First, calculate the target power of each unit, and then calculate the target power of each unit in the group, which solves the problem of uneven fatigue level of units, thus effectively balancing the limits of each unit. The power operation level is conducive to maintaining the stability margin of the unit object; at the same time, it reduces the number of start-stop conversions of the unit and reduces equipment loss; making full use of the grid load and other indicators to evaluate the start-stop queue improves the efficiency of the wind farm.
Description
technical field [0001] The present invention relates to the field of wind power, in particular to a method, device and electronic equipment for controlling active power of a wind farm. Background technique [0002] At present, some wind farms adopt the method of manual power adjustment, and the personnel on duty in the wind farm manually perform power limit control according to the difference between the dispatch command value and the actual power generation of the wind farm. There are also some wind farms that use the average power distribution method to evenly distribute the target power of the wind farm to each unit. When the distribution value of a unit is less than its minimum operating power, its distribution value is its minimum operation power; When the maximum active power is used, its assigned value is the maximum active power of the unit. In addition, a large part of the wind farms adopt the proportional distribution method of available active power, and distribu...
