摘　　要：目前,随着我国不断推进电网的智能化建设,现有的变电站继电保护测试技术急需得到改进以满足变电业务需求。本文为解决基于传统变电站继电保护测试过程中存在的测试数据无法自动读取、测试类型仍需手动输入、不能进行通信一致性调查等问题,研究设计了一种基于EPON网络的智能变电站继电保护测试技术,能够实现对智能变电站的保护装置、测控装置、智能终端的自动设定,同时进行通信一致性与可靠性检查的功能,该技术有望成为推动我国变电站智能化建设的重要举措或途径。At present,as my cONUtry continues to promote the intelligent construction of power grids,the existing substation relay protection testing technology urgently needs to be improved to meet the needs of substation business.In order to solve the problems that the test data existing in the traditional substation relay protection test process cannot be automatically read,the test type still needs to be manually input,and the communication consistency investigation cannot be carried out,this paper studies and designs a smart substation relay based on the EPON network.The protection test technology can realize the automatic setting of the protection devices,measurement and control devices,and smart terminals of the smart substation,and at the same time check the communication consistency and reliability.At the same time,the technology is expected to become an important measure to promote the intelligent construction of substations in my conutry way.
