Combined optimality and robustness assessments for interconnected power converters-theoretical and experimental results

DOI

説明

More reliable and a respective better power quality are the main requirements for any power supply system operating for a distributed power network, an industrial plant or, in a more particular case, for a train drive. A new algorithm to decide, compute and analyze a compensation method that improves the power system performance is proposed, based on a complex bilinear model of two parallel connected voltage-type power converters. Analysis is performed for normal and faulted operation, with emphasis on the combined purposes-input currents' quality and system's reliability. A specially computed term is used for the feedback compensation and an optimum parameter identification is explained providing a strong basis for a unified theory of analysis for hybrid bilinear (biconnected) systems. It is proved that the method acts automatically for any of the analyzed operation conditions, and an experimental approach proves the theoretical analysis.
