“…The frequent dynamic behavior of SMG will cause transient impact on the harmonic and THD calculations that is also very important for the PQ assessment in real time. As an example, Fig.11 (a) shows the transient impact on the 5 th and 7 th harmonics of bow thruster current due to the ballast pump start, which will also lead to the AC bus voltage transient dip and generator current surge [27]. It can be seen that these harmonic components increase in the voltage dip intervals.…”

Abstract-Power quality (PQ) is becoming more and more critical issue in shipboard microgrid systems (SMG). Especially, the impact of voltage unbalance combined with harmonic distortions on the SMG behavior has not been fully investigated. In this paper, simple power quality assessment models and a series of controlled experiments are proposed and carried out in a real ship under seagoing conditions. The ship experimental results are presented and discussed considering non-linear bow thruster load and high power ballast pump loads under unbalanced and harmonic voltage conditions. In addition, the analysis of bow thruster current harmonic surges during the ballast pump start-up is presented. Furthermore, the voltage/current distortions of working generator, bow thruster and pump loads are analyzed. The paper provides a valuable analysis for coping with PQ issues in the SMG.

“…The article concerns the analysis of processes and the operation of hybrid switches [1,2] related to the arcless switching off of short-circuit currents in power circuits operating in difficult environmental conditions [3,4]. In the conditions under consideration, the main cause of disruption of the power system operation is a dynamic short circuit, but one cannot omit such factors as vibrations, lightning, or changing weather conditions.…”

“…In the conditions under consideration, the main cause of disruption of the power system operation is a dynamic short circuit, but one cannot omit such factors as vibrations, lightning, or changing weather conditions. Such conditions occur, among others, in ship electric power systems or electric traction railway systems [4,5]. Due to the fact that the operation of switching off short-circuit currents refers to emergency states and is essential for the operational safety of the considered power system, the devices performing these operations, usually hybrid switches, belong to the group which can be referred to as critical devices for electric power system operation.…”

Abstract:The paper deals with a key issue, how to limit the hazard and assure reliability, safety and repeatability of operation of selected critical devices protecting electrical power systems. The main research is focused on the incorrect operation of hybrid switches caused by random disturbances of the thyristor gate signals in the electrodynamic drive coil power supply circuit. Firstly, a pilot experiment on the operation of hybrid circuit breaker actuators under random disturbance conditions was carried out and the results are presented. Next, an in-depth operation analysis, based on experimental and simulation research, according to setting conditions of the circuit breaker actuator parameters such as capacitance, voltage and switching time was performed. A simulation study with the use of a field-circumferential model in the Ansys Maxwell program of electrodynamic propulsion of rectilinear motion, which enables energy transfer from the capacitor bank to the actuator coil power supply at selected time intervals, was executed. The study analysed the impact of the discontinuity of energy transfer on the dynamic properties of the actuator and some recommendations for designers and users on how to limit this hazard are formulated.
