Improving electric power quality in ships via surge protection devices (SPDs)

摘要

Power supply quality (PSQ) problems in ship electrical systems are a major concern nowadays due to the electrification of most equipment on board. Among PSQ problems, voltage transients and spikes are probably the most important as they can cause a range of malfunctions and even damage. The most efficient method of protection against spikes and transients is the installation of surge protection devices (SPDs). This paper presents a holistic methodology of selecting the most appropriate installation points in the ship's electricity grid on the one hand while not resulting in new problems on the other.
