Problems solved by technology

Therefore, the above-mentioned wind farm power regulation method is not only highly dependent on the reliability of the corresponding unit, but also ignores the fatigue of the fan (such as the running time of the fan or the temperature of its electrical components, etc.) due to the random operation of the correspo

Example Embodiment

[0034] To enable those skilled in the art to better understand the technical solution of the present invention, the power adjustment method and power adjustment device of the wind farm provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0035] See figure 1 , Which shows a schematic flow chart of a method for power adjustment of a wind farm provided by the first embodiment of the present invention.

[0036] In step 110, the effective power demand value of the wind farm by the grid is collected in real time, and used as the target value for power regulation of the wind farm, that is, it is used as the target output power Pr of the wind farm.

[0037] In step 120, the working state of each wind turbine in the wind farm is collected in real time. The so-called working state includes: whether it is turned on, whether there is a fault, whether it is connected to the grid, and the current output active power value. Then, accor...

Abstract

The invention belongs to the technical field of wind power generation, and particularly provides a power adjusting method and a power adjusting device in a wind farm. The method comprises the following steps of: 1) acquiring an effective power demand value of the wind farm in real time, and taking the effective power demand value as target output power Pr of the wind farm; 2) acquiring the current actual output power P of the wind farm; 3) calculating a power adjusting value of the wind farm according to the current actual output power P and the target output power Pr of the wind farm; 4) determining a power adjusting strategy on the basis of the power adjusting value; and 5) controlling the working state of corresponding fans in the wind farm on the basis of the power adjusting strategy; and repeating the step 2) to the step 5), till the output power of the wind farm meets the power demand of a power grid. In the power adjusting method and the device provided by the invention, the output power of the wind farm can be adjusted in time and accurately, the stability and the safety of the operation of the fans are improved and the labor cost also can be greatly saved simultaneously.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a power regulation method and a power regulation device of a wind farm. Background technique [0002] With the continuous development of wind power, there are more and more wind farms with a large number of wind turbines. As a part of the power supply system, wind farms undertake the power supply task in response to the grid requirements. With the continuous improvement of grid-connected output power, the stability of wind farm grid-connected operation plays an increasingly important role in the stability of the entire grid power supply. Therefore, in practical applications, it is necessary to adjust the output power of the entire wind farm in real time according to the grid-connected power requirements. Specifically, the wind farm needs to receive power dispatching requirements from the grid in real time, and based on this, control the overall power generation of ...
