Abstract: 变流器长线传输供电对发电机端电压的影响已经引起了人们的足够重视,针对长线传输的研究已取得了一定的成果,然而电缆参数对发电机端电压的影响却未能引起足够的重视.电缆参数受电缆结构与敷设方式影响很大,现有的电缆参数计算与测试方法相对匮乏且受应用场所的限制.COMSOL Multiphysics具有强大的电磁场分析计算能力,基于电缆结构与敷设方式的不同,分别在COMSOL Multiphysics建立了仿真模型,通过仿真分析计算出不同电压频率下的电缆参数.然后依据变流器供电的发电机端电压等效电路,在Matlab/Similink软件中建立仿真模型,验证不同电缆参数对发电机端电压的影响.
