摘要
随着舰船综合电力系统的发展,系统配置、网络结构以及运行模式已经发生巨大改变,导致传统舰船继电保护方法无法满足安全性需要。分析了舰船综合电力系统的故障特征信号,提出了一种基于迁移支持向量机的智能继电保护方法。推导了所提出方法的数学模型,并建立了相应的仿真模型。在PSCAD/EMTDC软件中,构建舰船电力系统故障模型,对方法进行了对比分析,验证了其有效性。仿真结果表明:基于迁移支持向量机的智能继电保护方法,可以对舰船综合电力系统中复杂的故障进行判断,全方位满足保护要求。
With the development of ship integrated power system,the configuration,network structure and operation mode of it have been greatly changed.As a result,the traditional ship relay protection methods can not meet the needs of the system any longer.In this paper,the fault characteristic signals of ship integrated power system are analyzed.An intelligent relay protection method based on Transfer Support Vector Machine(TrSVM)is proposed.The mathematical model is derived and the simulation model is constructed in PSCAD/EMTDC software for comparative analysis to verify the proposed method.Finally,the results validate that the method in this paper is able to deal with the complex fault situation in the complex ship integrated power system and meet the relay protection.
