电气设备短路对舰艇电站的影响及措施

On Impact and Measures of Short Circuit on Ship Power Station

通过设备短路对舰艇电站的工况分析,阐述了电气设备短路时舰艇电力系统的短路电流变化和暂态稳定性过程,以及对电站所造成的各种影响。其对电站的影响,提出了适用于舰艇的限流方式FCL,使之与断路器相配合快速切除故障。从而提高电力系统暂态稳定性。

Based on the influence of the equipment short circuit on the ship power station, the paper analyzes the changes of the short circuit current and the process of the transient stability of the ship power station and the influence on the power station when there is an equipment short circuit.According to this situation, the paper puts forward a current limiting mode FBL on ships, which can cut off the current faults quickly by matching the circuit clearing equipment. The FBL mode can be regarded as one of the fast and most direct measures to improve transient stability of power system and plays a guiding role in the safe operation of power plant reliability.
