摘　　要：在介绍动力定位技术与解读相关规范的基础上,分析DP3船舶母联闭合电力系统短路保护的要求,结合实际案例进行系统短路保护设计和配置,提出一种适用于母联闭合中压电力系统的高效简洁保护方案。该方案在控制硬件成本的同时,保证了隐藏故障发生情况下短路故障的快速隔离。通过硬件在环仿真的试验方法对所设计的系统短路保护方案进行验证,证明了方案原理的正确性。Based on the introduction of the power positioning technology and the explanation of the related standards requirements, the short circuit protection requirements of shipboard closed bus-tie power system with DP3 symbol is analyzed. The design and configurations of the system short circuit protection is obtained combined with actual example, which can ensure the rapid isolation of short-circuit faults in the event of hidden faults while having a relatively low hardware cost. With the test method of hardware-in-the-loop simulation, the short-circuit protection scheme designed is verified, and the correctness of the scheme principle is proved.
