摘要:采用中压直流电网输配电是舰船综合电力系统的重点发展方向,但中压直流开关的分断能力不足
成为中压直流电网发展的一个重要制约。本文提出在合理位置加装电弧触发式混合型限流熔断器
(ATH-CLF)来限制中压直流电网短路电流的方法来解决这一问题。首先以 IEEE Std1709-2010推荐的
种舰船中压直流电网为例,建立了该电网的EMTP仿真模型和ATH-CLF的EMTP仿真模型,计算了有无
ATH-CLF以及ATH-CLF安装在不同位置时各典型位置发生短路的电网短路电流及母线电压跌落。分析表
明,合理的ATH-CLF加装方案可有效降低短路电流水平,并可使非故障区域的母线电压跌落在10ms之内
恢复。

Abstract: MVDC power system is the trend of ship 's integrated power systems, but the deficiency of the
MVDC switches' break capability become one of the main restriction of the integrated ship power systems
Arc-triggered hybrid current limiting fuses(ATH-CLF)used in advisable places could resolve this problen
effectively. At first, a kind of integrated ship power system recommended by IEEE is taken for instance, the
EMTP model is built to calculate the system fault current and bus votage drop when fault occurs in typical
places. Afiter that, EMTP model of the ATH-CLF is built to insert in the system model. System fault current
and bus voltage drop with different installation places of ATH-CLF is calculated and compared. Results
show that ATH-CLFS installed in advisable places can decrease the fault current level significantly
noticeable, and bus voltage drop in non-fault area can recover in less than 10 ms
Keywords: integrated power systems; arc-triggered hybrid current limiting fuse, MDC power systems,
