高冗余度、高可靠性直流区域供电系统设计

Design of a High Redundancy and Reliability DC Zonal Power Supply System

针对目前水面舰船直流电力系统现状,提出一种具有高冗余度、高可靠性的直流区域供电系统。该供电系统被划分为输入级、功率级与输出级。每一级电路均通过不同的结构设计或控制策略实现高冗余度,从而使整个系统的供电可靠性得到保证。阐述了上述供电系统的工作原理、控制策略与参数设计方法,并依据某一应用场合的指标进行了设计。试验结果验证了上述设计思路的正确性。

From the current situation of DC electric system of surface combatant ship,this paper proposed a high redundancy and reliability DC zonal power supply system. This power supply system is divided by input class;power class and output class. Every class circuit has high redundancy by different structure design or different control strategy,thereby the whole system has high reliability of power supply. This paper expounded the work principle、control strategy and parameter design of the system,and made the design according as a specifically occasion. The test result proves the validity of the design method.
