| Abstract: | Through analyzing the transient equations, this paper deduces the time-domain expressions of the rotor transient currents, obtains the change law of the rotor transient eurrents in contrast with different voltage dip ratios, and carries out the simulation experiment on the transient response of the doubly-fed wind power generator under grid three-phase short circuit fault condition. The result validated the proposed expressions of transient currents. |
