摘要
舰船电力系统使命的特殊性及系统配置的独特性使其继电保护策略与陆地电力系统有所不同。随着系统容量和网络结构的不断发展,以离线整定为特征的传统三段式电流保护已不能满足保护要求。通过分析舰船电力系统保护的特点和需求,提出基于拓扑识别的自适应保护策略,能根据系统网络拓扑结构自动在线调整保护整定值。典型实例的分析结果验证了其在改善保护性能方面的可行性及有效性。
For specific mission and unique configure of Shipboard Electrical Power Systems（SEPS）,their relay protection schemes are different from Terrestrial Electrical Power Systems（TEPS）.With development of system capacity and network topology,the traditional three-step current protection method can not meet protection demands,which has the feature of off-line setting.Based on the characteristic and requirement of SEPS,a new adaptive protection scheme based on topology-recognition is proposed,which can automatically adjust current settings of short-delay protection on-line according to power network topology.Analysis results of typical instance verify the feasibility and validity to improve protection performance.
