Theoretical andExperimentalResearchon Triggered-Vacuum-Switch-based Fault Current Limiter By ShiJing SupervisedbyProfessorZouJiyan ADissertation Submitted to theFacultyoftheGraduateSchool of Huazhong UniversityofScience andTechnology for theDegreeofDoctorofPhilosophy in Electrical Engineering April2华中科技大学博士学位论文 说明了TFCL限流方案是可行的。如果说实验还存在着实验场合的单相与实 际TFCL的三相之间的差别,那么应该说仿真计算则能更全面、更系统地反 映TFCL的限流能力。论文以PSCAD/EMTDC软件包为仿真工具,对多种短 路故障情况下有、无TFCL限流的三相电路进行了对比仿真计算,结果表明 TFCL对三相对称和三相不对称短路敌障均有良好的限流效果。无论是实验 还是仿真都是目前和进一步研究TFCL的必不可少的研究手段。华中科技大学博士学位论文 Inthelastpart of the dissertation,therelationshipbetweenTFCL andsystem transient stability is discussed,then brief summaries and conclusion are drawn,and further studies areproposed.Key words:Power system,Fault current limiter(FCL),Triggered vacuum switch(TVS),Series compensation,LC
