一种数字化继电保护装置即插即用系统的构建与实现

Construction and Implementation of a Plug-and-Play System for Digital Relay Protection Device

随着现代科技的不断更新,我国数字化水平也在持续上升,尤其是电力方面的研究把控的更加严格,现在继电保护系统是电力工程中比较受关注的问题,因为继电保护装置一直存在两种问题,一种是结构复杂,另一种是内在的插件更换过于困难,但是由于我国科技的不断创新,发明出了数字化继电保护装置即插即用系统,很大程度上解决了上述两种问题。文中简要阐述了即插即用系统的工作原理,并且根据实际描述出系统中应用了哪些技术,其中包括PNP文件目录库的建立、数据检验、系统通信控制以及信息作业流程处理,并通过实例证明即插即用系统的确可以提高变电站的维修效率。

With the continuous updating of modern science and technology, the level of digitalization in China is also continuously rising. Especially the research on electric power is more strict. The current relay protection system is a problem of concern in power engineering because There are two problems in relay protection devices. One is that the structure is complicated, and the other is that the internal plug-in replacement is too difficult. However, due to the continuous innovation of China’s science and technology, a plugand- play system for digital relay protection devices has been invented. The above two problems have been solved to a large extent. In the following article, the author briefly explains the working principle of the plug-and-play system, and according to the actual description, which technologies are applied in the system, including the establishment of the PNP file directory, data verification, system communication control and information. Job process processing. Finally, we prove by example that the plug-and-play system can indeed increase the maintenance efficiency of the substation.
