船舶高压电站短路故障保护算法研究

Short-Circuit Fault Protection Arithmetic of Marine High Voltage Power Station

对船舶高压电站中的短路故障进行了分析,提出了基于相敏保护的对称性短路保护和基于负序电流的不对称性短路保护方法,并进行了仿真实验。仿真结果表明,这两种故障保护算法具有较高的可靠性和实时性,能够满足船舶高压电站短路故障保护的要求。

This paper analyzes the short-circuit fault of marine high voltage power station, proposes a symmetry short circuit fault protection methods based on phase-sensitive protection and a asymmetric short circuit fault protection methods based on negative sequence current, and makes the simulation experiment. The simulation results show that those fault protection methods have higher reliability and real-time performance, and it can meet the requirements of short-circuit fault protection of marine high voltage power station.
