Abstract

This paper analyzes the behavior of a highly capacitive DC marine network under fault conditions and demonstrates how overvoltages can be caused by the redistribution of stored energy following the clearance of a fault. This energy flow can be complex in nature, making it particularly difficult to sufficiently protect the network effectively. Through the analysis and simulation of a representative zonal DC marine network, this paper analyzes the causes and severity of overvoltages which can occur following a fault, identifying key contributing factors. The paper also demonstrates how the effects of a fault on the network can propagate, potentially causing damage to previously healthy parts of the network. Through this analysis, this paper identifies options for the mitigation of overvoltage transients in DC marine electrical systems.
船用直流电气系统的过电压缓解
本文分析了高容性直流海洋电网在故障条件下的行为,并演示了故障清除后存储能量的重新分配如何引起过电压。这种能量流在本质上可能是复杂的,因此特别难以有效地充分保护网络。通过对具有代表性的海上分区直流电网的分析和仿真,分析了故障后过电压产生的原因和严重程度,找出了造成过电压的关键因素。本文还演示了故障对网络的影响如何传播,可能对网络先前健康的部分造成损害。通过分析,本文确定了缓解直流船舶电气系统过电压瞬变的方案。
