摘　　要：介绍了虚拟仪器技术以及虚拟仪器的硬件和软件的基本构成原理,提出将虚拟仪器技术应用于电力系统继电保护实验教学中。设计了一套继电保护虚拟仪器系统,并在此基础上对零序保护和距离保护进行了仿真实验,实验结果表明,把虚拟仪器技术应用于电力系统实验教学中具有广泛的前景,是今后一段时间的发展方向。Virtual instrument technique and basic composition principles for the software and the hardware of the virtual instruments are introduced. Virtual instrument technique is used in lab teaching of protective relaying. A protective relaying system based on virtual instrument is designed and a simulation experiment of zero-sequence protection and distance protection based on virtual instrument is done. The results show that virtual instrument technique can find a wide application in power system and can be a development direction in the future.
