Abstract

Synchronous machine fed load-commutated power converters (SMLCCs) are commonly used for DC power sources in marine and aircraft power systems. The focus of this paper is to set forth a model for SMLCCs for use in transient stability studies involving these systems. Although there has been considerable work in this area, much of this work has assumed the existence of a DC link inductor whereupon the DC link current is approximately constant. In practice, this filter is often eliminated, whereupon previous models are no longer valid. A new average-value model is set forth for SMLCCs in which there is no DC link filter inductor. The model is validated both experimentally and through the use of a detailed computer simulation
