选择性保护分析在船舶电力系统中的应用

Application of the Selective Protection Analysis in Ship Power System

船舶电气设备能否安全可靠地工作是船舶货物和人员安全的保障。文章以1 000 t油轮为例,通过计算该船电力系统短路电流对断路器进行选型和整定,并利用ABB公司的DocWin软件验证了该船电力系统选择性保护的可靠性,为船舶电力系统设计提供了参考。

Whether the Ship electrical equipment can work safely and reliably plays an important role in the ship goods and personnel safety.This paper makes use of ABB company’s DocWin software to verify the reliability of the selective protection of the ship electric power system,taking a 1000 tons of oil tanker as an example,through calculating the ship power system short circuit current to deciding circuit breaker selection and setting,which provides the reference to the ship electric power system design.
