GB/Z 165-2025 Electrical installations in ships—Primary DC distribution—System design architecture

Scope

This document specifies the requirements for a DC distribution system and interconnection devices.
The requirements of this document establish the following general principles:
—— The operation of the system can reduce environmental impact without compromising the safety of devices and personnel;
—— Existing and new generator units, used in advanced control concepts for power, energy storage, and total power balance, including semiconductor converters (AC-DC, DC-DC, DC-AC power converters) and dynamic load controllers; and
—— Related system studies and calculations used to verify protection concepts that meet the necessary selectivity, isolation methods, and equipment requirements.
This document can also provide guidance for energy integration of different types and suitable methods for identifying the appropriate locations of such devices.
