Abstract
The disclosure provides a frequency support method, device and wind farm for a wind farm and belongs to the technical field of new energy power generation and grid connection. In the frequency support method, a state that can reflect a frequency modulation capability of a wind turbine is designed, measured, and recorded as a consistency factor of frequency modulation. Each wind turbine is controlled to exchange the consistency factors with two adjacent wind turbines. Each wind turbine combines its own consistency factors with the consistency factors of two adjacent wind turbines to generate consistent added power through a PI link and adjusts real-time frequency modulation output based on the consistency added power. In this way, the states of the wind turbines in the wind farm are similar during the frequency support process, so that a reasonable distribution of frequency support power is achieved.
