摘　　要：针对电力系统暂态故障时间短导致使用仿真器调试不便的缺陷,运用MATLAB与C混合编程方式,在PC平台上实现了对继电保护装置保护应用程序的仿真验证。采用MEX函数接口实现读取故障波形和MATLAB仿真波形,并将数据转化为电流、电压通道的数据流,实现对继电保护故障的模拟。该系统可直接移植DSP程序代码,保证了保护应用代码与仿真验证代码的一致性,提供了脱离继电保护装置的试验验证环境,能使用各种录波波形验证保护程序逻辑。在设备运行过程中,针对现场故障,可采用该系统进行单步跟踪调试,准确判断装置保护程序逻辑正确性。实际运行表明,本系统不依赖于保护装置硬件,缩短了新型继电保护装置的研发流程,提高了研发效率。Since the transient fault time of power system is very short,it is not convenient to debug the application program of relay protection with emulator,for which a simulation and verification system is developed with MATLAB and C Ianguage on PC platform. The power system fault waveforms and MATLAB simulative waveforms are read by MEX function and converted into the data streams of current and voltage channels for the fault simulation of relay protection. DSP source program can be directly transplanted to the system to ensure the program to be tested is just the same program in DSP. The system provides the test environment without the relay protection and verifies the logic of protective program with different fault waveforms. For the site fault,its single-step tracking function can be used to confirm the correctness of protective logic. Practical operation shows that,not depending on protection hardware ,the system shortens the development process of new type protection device,and increases the R＆D efficiency of relay protection.
