Embodiment Construction

[0025] Embodiments of the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present invention more clearly, and therefore are only examples, rather than limiting the protection scope of the present invention.

[0026] Such as figure 1 As shown, the control system block diagram of a wind turbine active power fine adjustment method provided by the present invention includes the following modules: receiving grid active power dispatching instructions, active power pre-adjustment module, wind farm actual active power, and power distribution module. Receiving the dispatch command of the grid is to obtain the target value of the active power of the wind farm. The actual active power of the wind farm is a summary of the wind turbine operating data of the wind farm monitoring system. The main function of the active power pre-adj...

Abstract

The invention belongs to the technical field of wind power regulation, and in particular relates to a fine regulation method for the active power of a wind turbine. The beneficial effect of this patent is: the present invention divides the active power distribution into two links of coarse adjustment and fine adjustment to realize the fine adjustment of active power, while improving the quick response and precise control of the active power adjustment of the wind farm, considering the wind power The influence of the active power control residual error of the wind farm, so that the active power dispatching can form a closed loop, which effectively reduces the adjustment frequency and adjustment range of the active power of the wind turbine, and can quickly and accurately regulate the active power of the wind farm and improve the wind turbine. The service life ensures the healthy operation of wind turbines and realizes fine scheduling, so as to further improve the power quality after the wind farm is connected, and effectively ensure the stability of the power system.

Description

technical field [0001] The invention belongs to the technical field of wind power regulation, and in particular relates to a fine regulation method for the active power of a wind turbine. Background technique [0002] As one of the main forms of clean energy utilization, wind power has developed rapidly in recent years. With the gradual increase of the installed capacity of wind turbines, its proportion in the power grid has also gradually increased. With the increasing proportion of wind power generation in grid power generation, the huge challenge brought by the fluctuation of active power of wind farms to the safe operation of grid cannot be ignored. As far as the development trend is concerned, in order to ensure the reliable and stable operation of wind farms, integrate wind farms into the grid dispatching system, and realize active power control of wind farms, it is the development demand for safe grid-connected operation of large-scale wind farms. [0003] With the i...
