Overview This recommended pract

Target users for this recommended practice are evaluators and designers of electrical power systems for commercial marine and military applications, commercial and military ship end-users, shipbuilders, port operators, classification societies, mac
39、hinery and equipment manufacturers, research institutes, and universities. 1.1 Scope This recommended practice is based on current electrical engineering methods and practices for applying 1 kV to 35 kV MVDC power distribution and DC power delivery systems on ships. Recommendations are made for anal
40、ytical methods, preferred interconnection interfaces and performance characteristics for reliable integration of MVDC electrical components into the ship electrical power systems. 1.2 Purpose The purpose of this document is to recommend a methodology for analysis and specifications parameters for 1

42、es, sizing, life cycle cost, weight, efficiency and risk reduction of MVDC power systems implementation. It will compliment the IEEE Std 45-2002.11.3 Power electronics in MVDC power systems Recent successes in the development of fast switching medium-voltage power semiconductors made it possible to
43、realize such advantages of DC power distribution over AC as: Simplifying connection and disconnection of different types and sizes of power generation and storage devices. Reducing the size and ratings of switchgear. Eliminating large low-frequency (50 Hz or 60 Hz) transformers. Limiting and managin
44、g fault currents and enabling reconfiguration. Eliminating reactive voltage drop. Enabling bi-directional power flow. Reducing power system weight by using high speed generators. Enabling higher power ratings for a given cable size. Improving control of power flows, especially in transient and emerg
45、ency conditions. Reducing fuel consumption by allowing variable speed prime mover operation. Improving efficiency when energy storage and power conversion from batteries, fuel cells, and emergency generators is required. Eliminating the need for phase angle synchronization of multiple sources and lo
46、ads. Figure 1 illustrates a concept of the MVDC distribution power system in which every electrical power source and every electrical load are connected to the MVDC bus via power electronics.

The system shown in Figure 1 Xmay be expanded with redundant generators of large and small size, redundant storage systems of different kinds, two variable speed propulsion drives, etc., or there may be two redundant MVDC
49、systems. All loads requiring an independent ground should be connected to the medium-voltage DC bus via a means such as compact high frequency transformers. Converters will accommodate reactive power required for loads. To reduce the system size and weight, transformers between generators, propulsion motors and the DC bus may be eliminated. Furthermore, with the capability of power electronics to control and interrupt current, most load-side circuit breakers may be replaced by simple switches such as DC disconnect switches. In case of a
