Floating heavy metal berth with energy pontoon PMT project 15163

Purpose
In the power pontoon is installed a set of equipment for receiving from the shore power voltage 6kV, conversion to 0,4kV and distribution within the power pontoon, as well as there are networks and electrical equipment with shields for power supply voltage 400V, 50Hz up to 1600A (ShchZP), DC network up to 4000A voltage 210-315V (ShchZP), network voltage 230V, 400Hz up to 160A (ShchP-400). The number of shields is provided by the project.
Receiving electricity from the coast voltage 6kV provide two high-voltage switchgear VRU1 and VRU2, which are divided into four feeders.
Two feeders provide power to KTP #1 and KTP #2
Two feeders supply the converters. To convert alternating current voltage 400V 50Hz into alternating current voltage 230V 400Hz on the power pontoon install three static converters with output power of 50kW each, one of which is redundant.
To convert the alternating current into direct current...
