摘　　要：利用Qt的快速界面开发技术及其丰富的库类,开发出继电保护装置仿真培训软件,该平台采用积木式结构,根据保护原理方便地调换不同模块,可对保护的动作过程进行直观的显示;此外平台还利用Matlab强大的仿真功能,可进行电力系统中各种故障的仿真,获得的三相电压、电流波形及保护动作波形,并借助Qt显示在前台界面上。通过该平台,学员能直观比较不同厂家同类保护装置的动作逻辑,并提高故障分析能力。A method based on Qt and Matlab is presented for protection simulation. The building block method is adopted in the design of platform. According to different principle of relay,different models can be changed,and process of relays can be observed in the platform. Using Matlab, the system can simulate all kinds of faults. Three-phase voltage, current waveforms and the protection operation waveform are achieved and displayed on Qt interface. So it is useful for trainees to improve the ability of fault analysis.
