摘要/Abstract

摘要： 针对DP-2或DP-3级船舶中压闭合母排电力系统高冗余性和容错性的保护需求，提出一种兼顾快速性与可靠性的选择性保护方案，旨在解决单点故障叠加隐性故障下的故障隔离难题，确保失电区域不超过动力定位系统最大允许失效范围，通常为一段中压主母排。基于闭合母排电力系统运行特性，将中压系统中每段主母排划分为发电机、母排、负载馈线及母联电缆4类保护区域，通过差动保护与方向纵联保护的协同配置构建主保护或后备保护两层保护。依托典型DP-2级船舶的6.6 kV闭合母排架构，搭建了包含一段主母排上各类综合继电保护装置硬件与数字实时仿真系统的硬件在环(HIL)测试平台，在4类区域完成单点故障叠加隐性故障的8种运行工况的模拟测试，分别测试4类区域上主、后备保护的有效性，结果表明保护系统在故障电流水平动态变化的各类工况下均可正确动作，验证了所提保护方案的协调性、可靠性和快速性。

Abstract: In response to the protection requirements of high redundancy and fault tolerance for closed bustie medium voltage power systems in DP-2 or DP-3 class ships, a selective protection scheme that balances reliability and rapidity is proposed to solve the problem of fault isolation under single-point fault superimposed with hidden faults, ensuring that the power loss area does not exceed the maximum allowable failure range of the dynamic positioning system-typically one section of the medium-voltage main busbar. Based on the operational characteristics of closed bustie power systems, each section of the medium-voltage system is divided into four protection zones: generator, busbar, load feeder, and bustie cable. A two-tier protection scheme consisting of primary and backup protection is constructed through the coordination of differential protection and directional pilot protection. Based on the 6.6 kV closed bustie power system architecture of a typical DP-2 class ship, a hardware-in-the-loop (HIL) test platform including various types of integrated relay protection devices in one section of the main busbar and digital real-time simulation systems was built. Simulation tests were conducted in four types of areas with eight operating conditions including single point faults and superimposed hidden faults, testing the effectiveness of both primary and backup protections in each zone. The results showed that the protection system could operate correctly under various operating conditions with dynamic changes in fault current levels, verifying the coordination, reliability and rapidity of the proposed protection scheme.

Key words: closed bustie, selective protection, regional protection, hidden fault, hardware-in-the-loop
