### Re: What's the exact meaning of HubIner?

Thank you Jason! It does make sense now. But when I check the relation among RotIner, inertia of each blade about the LSS and the HubIner, there is still a little confusion to me. Just taking the WindPACT 1.5MW Wind Turbine for example: HubIner=34600(kg*m^2);RotIner=2962443.900;Inertia of each blade...

### What's the exact meaning of HubIner?

Hi, I am trying to do a linearization of the one state wind turbine model: J*(d_omega/dt)=0.5*Cp*rho*A*V^3/omega-N*tao_g. In this expression, J is the total inertia of all parts of rotation. It should be expressed like this: J=J_L+J_H*N^2; J_H is the inertia of the high speed side which is correspon...
