摘要
针对数字化继电保护装置配置复杂且插件更换困难的现象,设计出数字化继电保护装置即插即用系统,研制了PNP手持部署终端,详细阐述了即插即用系统的体系结构及工作原理,描述了系统中使用的关键技术,包括PNP文件目录库的建立方法、数据无损校验、系统通信控制连接和信息作业流程处理。最后通过试验验证该系统能够很好的实现数字化继电保护装置插件的即插即用,大大提高了智能变电站运维效率。
In view of the configuration of digital relay protection device is complex and the plug-in replacement is dif- ficult, this paper designs the plug and play system in digital relay protection device, develops a PNP handheld termi- nal deployment, and elaborates the system structure and working principle of the plug and play system in detail, meanwhile, it describes the key technologies used in the system, including the establishment methods of the PNP file directory library, data check, system communication process control connection and information processing. Finally, the results verify that the system can achieve good plug and play in digital relay protection device, which greatly im- proves the efficiency of intelligent substation operations.
