摘要(Abstract)：

介绍了一种基于虚拟仪器技术与FPGA技术的继电保护二次回路仿真系统。利用LabView可视化编程语言,对二次回路的实体形态进行模块化编程形成元件库,调用元件库并进行逻辑组态,实现二次回路的精确仿真。通过对RADSS母差保护二次回路的实例仿真,再现了寄生回路与接点竞争现象,验证了母差保护二次回路存在的缺陷,有助于提高电网运行的安全可靠性,构建的二次回路仿真系统具有良好的应用效果。
This paper introduces a simulation system of secondary circuit based on virtual instrument technology and FPGA technology.LabView visual programming language is used for modular programming,the programming of physical form of the secondary circuit is implemented to form the element library and component library is transferred for logic configuration for the purpose of accurate simulation of secondary circuit.By simulation on secondary circuit for RADSS busbar differential protection,the paper reflects the rivalry between parasitic circuits and contacts,and defects of secondary circuit for busbar differential protection are checked,which helps to improve safety and reliability of power grid operation.The simulation system of secondary circuit established is effective in application.
