Abstract

The invention provides a rapid frequency modulation control method suitable for a wind power generator set. The rapid frequency modulation control method comprises the steps that S1, power station operation parameters including frequency, voltage and active power are collected; S2, the maximum frequency deviation is obtained through analysis, the active power difference value corresponding to the current frequency is calculated according to the maximum frequency deviation, the active power difference value is the difference value between the mechanical power of the wind power generator set and the active power reference value adopting the maximum power point tracking algorithm, and the active power difference value comprises a system power change value caused by virtual inertia control; and S3, according to the calculated active power difference value, by combining the active power-rotating speed relationship of the wind power generator set, the operation parameters of the wind power generator set are adjusted according to a preset control strategy. According to the invention, a wind power system, especially a doubly-fed wind turbine generator, can have frequency response characteristics, can effectively and quickly participate in system frequency modulation, and reduces or avoids negative effects on system frequency modulation.

Description

technical field [0001] The invention relates to the technical field of frequency modulation control of wind power generating sets, in particular to a fast frequency modulation control method and system suitable for wind power generating sets. Background technique [0002] As a kind of clean energy, wind energy has been paid more and more attention by countries all over the world. Because wind power is rich in resources and can be developed on a large scale, the proportion of grid-connected capacity is getting higher and higher. [0003] At present, the main technology of wind power adopts doubly-fed wind turbines, which have excellent active and reactive power decoupling control performance to meet the technical requirements of constant frequency control, and the rotor speed and system frequency are completely decoupled. [0004] The increasing proportion of wind power grid-connected capacity and the technical requirements of constant frequency control make wind power unabl...
