Abstract

The invention relates to a wind turbine frequency regulation method and device, a computer device and a storage medium. The method comprises the steps that parameter tuning is carried out on a wind turbine to acquire the initial exit frequency time of the wind turbine; according to the initial exit frequency time, parameter tuning is carried out on the wind turbine again to acquire the unit adjustment power of the wind turbine; according to the initial exit frequency time and the unit adjustment power, parameter tuning is carried out on the wind turbine again to acquire the virtual inertia coefficient of the wind turbine; and according to the unit adjustment power, the initial exit frequency time is re-adjusted to acquire the final exit frequency time of the wind turbine. The method can beused to realize the auxiliary frequency modulation of the wind turbine based on the influence of the second drop of the frequency of a power system connected with the wind turbine.

Description

technical field [0001] The present application relates to the technical field of power system frequency modulation, and in particular to a wind turbine frequency modulation method, device, computer equipment and storage medium. Background technique [0002] In a large-scale wind power cluster, due to the decoupling characteristics of wind turbine speed and power system frequency, the rotational inertia of the power system will be reduced and the frequency response characteristics will be changed, resulting in severe challenges to the frequency stability of the power system. Therefore, it is necessary to allow wind turbines to participate in auxiliary frequency regulation in the power system, thereby improving the stability of the frequency of the power system. [0003] However, the traditional solution is to use a variable-speed constant-frequency wind turbine and perform parameter adjustment according to its own available frequency regulation capacity to realize auxiliary f...
