Dear Kaiyu.Fang,
Yes, I agree that Jg = 534.116 kg-m^2 for the NREL 5-MW baseline wind turbine (referenced to the high-speed shaft). When the rotor is modeled rigidly (without blade flexibility, then the rotor inertia (Jr) is calculated internally by the ElastoDyn module of OpenFAST and reported in the summary file (called RotIner). The value reported for the NREL 5-MW baseline wind turbine is 38759236 kg-m^2 (referenced to the low-speed shaft).
Regarding Kr and Kg from your figure, I believe a similar question was discussed in the following forum topic: Wind Turbine Modeling - #6 by Jason.Jonkman.
Best regards,
