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 continuous development of the ship power system, the system configuration, network structure and operation mode have been greatly changed compared with the traditional ship power system. The three-stage current protection method characterized by off-line tuning can not meet the requirements Based on a comprehensive analysis of traditional relay protection features, this paper proposes a self - adaptive protection strategy for the ship power system, and automatically adjusts the protection settings online using the network structure and system status, which can effectively improve the sensitivity and selectivity of the protection.
