The International Electrotechnical Commission (IEC) has released IEC PAS 63108:2017 . This standard applies to Electrical installation in ships – Primary DC distribution – System design architecture, and is now available at the IEC webstore.
Description: “IEC PAS 63108:2017 specifies the requirements of primary DC distribution systems and interconnected installations.
The requirements of this PAS establish general principles for
– operations, without degrading unit and human safety, capable of a reduced environmental footprint,
– existing and new power generating units, new DC distribution concepts for electrical power, energy storage and advanced control of a total power balance, including semiconductor converters (AC to DC, DC to DC and DC to AC power converters) and dynamic load controllers, and
– relevant system studies and calculations demonstrating a protection philosophy as needed for necessary selectivity, segregation methods and equipment.
This PAS also gives guidelines for integration of energy sources of different nature and suitable ways to identify locations of such installations.”
