中文摘要: 介绍了继电保护测试仪的原理和软硬件开发过程.该装置下位机硬件采用ARM嵌入式结构实现整体控制和数据处理;软件采用μC/OS-II嵌入式实时操作系统对系统任务进行管理.分析了现有继电保护测试仪稳态和暂态数据生成方法的优缺点,在此基础上提出了一种结合PSCAD仿真软件搭建仿真模型,并通过解析PSCAD输出文件作为故障数据的新方法.最后,通过将还原波形与PSCAD波形对比定性分析和作差定量分析,验证了本方法的可行性.
Abstract:The principle of digital relay protection tester,hardware and software development process are described.The hardware of the system is designed by ARM+DSP embedded structure and data processing;the software uses μC/oS-II embedded real-time operating system to manage the system tasks.The advantages and disadvantages of steady-state and transient data generation methods are analyzed,which are used in existing digital relay protection tester.On the basis of these methods, a new method is proposed and PSCAD simulation model is built by combing substation.Then,PSCAD output file and treating are analyzed as the fault data.Finally, qualitative analysis is carried out by comparing the restored wave with PSCAD wave and quantitative analysis is completed by subtracting in order to validate the feasibility of this method.
