Abstract

The transient behavior of wind-driven induction generator is analyzed. The generator is assumed to be running at steady-state with a certain real and reactive power flow conditions when a sudden disturbance occurs. An example of the disturbance may be a sudden disconnection from the utility grid. The generator is modeled using the universal machine model and the grid is represented by a constant voltage source. It is found that dangerous overvoltages occur a few seconds after disconnection from the grid due to self-excitations at the new higher speed
