The present invention provides a maintenance operation method for a wind turbine generator and a wind turbine generator, which can effectively utilize a phase advance capacitor equipped in the wind turbine generator and contribute to the phase factor improvement of the system side. A maintenance operation method for a wind turbine generator including an induction generator 3 driven by rotation of blades 2, a power output line 5 for outputting power of the induction generator 3 to a distribution system 5, and at least one phase advance capacitor 10 parallel--connected to the power output line, comprises: a first step of releasing connection between the phase advanced capacitor 10 and the power output line 5 when a maintenance mode is selected; and a second step of returning the connection between the phase advanced capacitor 10 and the power output line 5 by a manual operation or an automatic operation, wherein the phase advance capacitor 10 returned to the connection with the power output line 5 performs a power factor improvement of reactor loads 53, 54 in the distribution system 50 side through a linkage portion 60 with the distribution system 50.
