摘　　要：继电保护软件模块化设计使软件和硬件解耦,可以在只有录波数据但没有装置硬件的前提下调试软件程序。提出了一种基于分层软件架构(驱动层、公共应用层、专用应用层)设计的继电保护装置虚拟机方案,用虚拟驱动代替硬件驱动程序,公共应用层、专用应用层的源码完全移植,经MATLAB编译器生成动态链接库函数——保护计算与判据的MEX文件,利用Visual C++的调试进程捕捉功能实现装置虚拟机的录波数据输入、继电保护逻辑判据以及继电保护判读结果输出的串行时序执行,同时支持软件断点设定和单步调试,并提出了保护判据的批量开环验证和闭环验证的实现方案,经试验证明了其可行性。装置虚拟机在开发前期阶段软件调试不受制于硬件,在开发后期阶段可通过断点设定分析现场故障录波数据,大大提高了软件开发效率。As decoupling of software and hardware is made possible by modularized relay protection software, software can be debugged with only oscillo record data but without any hardware device. A virtual device implementation is put forward based on three software layers （driver layer, common application layer, special application layer）. A dynamic link library function is generated by the MATLAB compiler using the virtual driver to substitute for hardware driver, transplanting all common application and special application software. A virtual device MEX function is composed of protection calculation and criteria can be captured using the Visual C＋ ＋ debugging process to realize serial time sequence execution of oscillo data input, relay protection criteria, relay protection outcome while supporting software breakpoint setting and single-step debugging in the Visual C＋＋ process. The scheme for open loop batch verifying protection criteria and closed loop verifying protection criteria is presented, the feasibility being proved by test data. The virtual device software debugging is not subject to hardware in the early R＆D stage, while field fault oscillo data can be analyzed in the later stage with breakpoint settings, greatly increasing R＆D efficiency.
