Method for finely adjusting active power of wind turbine generator

Abstract

The invention belongs to the technical field of wind power regulation and control, and specifically relates to a method for finely adjusting the active power of a wind turbine generator. The method has the beneficial effects that the active power is distributed into two links of coarse adjustment and fine adjustment so as to realize fine adjustment of active power, and the influence of the activepower of a wind power plant on residual error control is considered while the active power of the wind power plant is improved to adjust rapid response and control accuracy, a closed ring can be formed by the dispatching of the active power, the adjustment frequency and adjustment amplitude of the active power of the wind turbine generator are reduced effectively, the active power of the wind power plant can be regulated quickly and accurately, the service life of the wind turbine generator is prolonged, healthy operation of the wind turbine generator is guaranteed, and fine dispatching is realized, so that the quality of electric energy after the wind power plant is connected is further improved, and the stability of an electric power system is guaranteed effectively.

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 expanded. 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 im...

Problems solved by technology

The limitation lies in the accuracy of unit generation capacity prediction, which will affect active power dispatching

At the same time, the arrangement described in the article is based on a certain order, because the momentary change of the arrangement order will cause the unit to be adjusted frequently and affect the service life of the unit
