Abstract

This project provides PQ assessment methods for SMGs under both unbalanced and harmonic AC bus voltage conditions. The impact of voltage unbalance combined with harmonics on the SMG behaviors are analyzed, some models and controllable experimental research are proposed and carried out in a real ship under sea-going conditions. The experiments are presented considering real non-linear bow thruster load and high power ballast pump loads at steady and transient conditions. In addition, the transient impact of voltage dips has been carefully analyzed based on maritime standards methods. The research work done proposed modelling methods based on the critical ship system parameters, which can be easily applied for PQ assessment onboard. Moreover, voltage dips caused by pump loads can lead to generator unbalanced fundamental current and harmonic current surges, which also have been analyzed.
