Abstract

During the past few years, lowering the pollution level in harbors has been the subject of various projects. The main idea is to supply the ship´s electrical system when berthed from a shore distribution network so the on-board generators can be turned off. The Shore Connection Distribution Grid represents an HV electrical infrastructure with a static frequency conversion substation. To ensure ship protection discrimination, the Shore Connection Distribution Grid needs to provide sufficient short-circuit current values. The aim of this paper is to show how it is possible to increase the short-circuit current inside a Shore Connection Distribution Grid. This paper proposes a set of feasible solutions to increase this current while also taking into account economic and technical aspects. Simulations are carried out in order to assess each proposed solution.
