舰船电力系统自适应保护技术研究

Study on Adaptive Protection Technology for Shipboard Power System

随着舰船电力系统的不断发展,系统配置、网络结构和运行模式等方面较传统舰船电力系统都发生了较大的改变,以离线整定为特征的三段式电流保护方法已不能满足要求.在全面分析传统继电保护特性的基础上,提出舰船电力系统自适应保护策略,利用网络结构和系统状态自动在线调节保护整定值,可以有效地提高保护的灵敏性和选择性.

With the development of warship power system, system configuration, electric network topology and operating pattern has change a lot. The three-stage relay protection cannot satisfy demands, which has the feature of off-line setting. Based on the characteristics of traditional protection method, adaptive protection schemes for warship power system are proposed, which adjust protection settings using network topology and system state automatically to improve sensitiviy and selectivity.
