This paper describes a full-power converter based test bench to generate voltage sags for fault ride-through (FRT) testing of the full-power converter based wind turbine drive. Principles of the test bench control and the generation of different types of voltage dips are explained. Proposed test bench is also briefly compared with the shunt impedance based voltage dip generation system in terms of...
Due to the unequal weighting of samples of measured signals, there is considerable uncertainty in the variance estimate based on a spectral density estimate computed by the method of averaged periodograms. Especially, if the signals contain non-stationary components randomly distributed along the data, careful design of a computation procedure is needed. In this paper the effect of windowing on the...
