摘　　要：提出了用虚拟仪器仿真研究微机保护动作性能的新方案。采用虚拟仪器(LabVIEW)的图形化的设计语言建立微机保护模块库。通过LabVIEW和MATLAB混合编程的思想建立启动模块、算法模块、逻辑处理基本模块等,利用LabVIEW特有的控件实现微机保护的动作逻辑关系,借助LabVIEW的模板操作功能建立仿真系统。现场实验表明,此方案符合现场实际动作情况,具有操作方便,直观、可视的优点,可以对各种类型的微机保护进行仿真,可用于继电保护误动或拒动后的事故分析。设计的仿真系统已用于教学实验和人员培训中。A novel project of simulation for distance protection is presented in this paper. The simulation module library in the simulator system of microcomputer protection is established by adopting the Laboratory Virtual Instrument Engineering Workbench （LabVIEW） and MATLAB program, the common modules include boot module, algorithm module and logic processing module etc. The operation logic of microcomputer protection is implemented by LabVIEW. Spot experiments show that this idea suffices for types of relay protection simulation. The method has such advantages as convenient operation, clearly and directly observable. And it can be implemented in teaching, training and be used for ascertaining the cause of the maloperation or misoperation of protective relaying in troubles.
