Abstract

This paper presents the performance study of several compensation schemes for a line-commutated SCR converter operating under a wide range of dc voltage. The studied reactive power and harmonic compensation schemes include passive filters, active filters, and hybrid compensation methods for a SCR interfaced permanent magnet generator based variable speed wind turbine. The effectiveness of the compensation schemes has been investigated in terms of reactive power and harmonics. The required compensation current ratings of these schemes are presented. The effects of higher pulse number of the converter on the compensation schemes are also considered.
