Abstract

This paper presents a detailed experimental study of wind turbine DFIG response to non-zero grid faults that may occur at a considerable distance from the generator. An analytical solution of the generalized DFIG machine equations operating under non-zero fault conditions is developed in which the fault response is separated into three components: a natural response that describes zero voltage behavior, a component describing the retained voltage behavior and the forced response corresponding to the applied rotor voltage via the rotor-side power converter. The DFIG system fault response is examined experimentally using a 7.5kW test facility detailing example of a 500ms, 15% fault.
