Blade Inertia

Hello and sorry in advance if this is not necessarily the proper venue for this question but I was curious if someone could help answer a question I have.

I am aware of the fact that rotor speed control is somewhat limited by the inherent inertia contained within the rotor and blades. However, in reading I have been unable to find anything that quantifies this inertia in terms of a temporal sense. As in, if there is a gust or lull that passes through the rotor how long temporally before that gust or lull passing through the rotor manifests itself in the generator time history or power output.

I know that it is heavily dependent upon the mass and length of the blades and additionally probably the pitch/operating conditions of the turbine but was just curious if anyone had a general idea of this temporal scale for a modern size turbine.

Any help would be greatly appreciated, thanks!
