Telecommunications equipments are one of the most critical loads to be supplied. In order to fulfill their imperative need for reliability, an energy storage system must be included and an efficient power converter must be added to meet the telecommunications equipment strict requirements. This paper intends to simulate an energy storage system, as part of a photovoltaic/fuel cell supply, with the...
This paper addresses the condition monitoring and diagnostics of twelve-pulse load commutated inverter drive systems, focusing on the occurrence of faults of the open-switch type in the power converters. The results presented are based on different monitoring techniques, namely, mechanical vibrations, axial leakage flux and temperature measurements. The goal of this study is to analyse the variations...
