Embodiment Construction
[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0037] Such as image 3 As shown, a method for suppressing the grid-connected subsynchronous oscillation of a double-fed wind farm, the steps are as follows: S1, determine the frequency range of the wind farm grid-connected subsynchronous oscillation.
[0038] Specifically: S1.1, according to the parameters and working conditions of the wind farm, establish a numerical simulation model of the wind farm, such as figure 1 shown.
[0039] S1.2. According to the...
