摘要
为确保支持IEEE 1588精密时间协议(precision timeprotocol,PTP)的各厂家智能设备能互连互通及稳定时间同步,对此类设备进行IEEE 1588一致性测试是十分必要的。为此在简要介绍IEEE C37.238—2011(电力PTP Profile)基础上,提出了电力系统IEEE 1588一致性测试的测试方法,分析了IEEE 1588一致性测试应具备的测试结构,描述了基于测试案例的一致性测试流程,详细说明了IEEE 1588一致性测试的测试内容,总结了IEEE 1588一致性测试的实施关键点。
To ensure the interconnection, intercommunication and stable time synchronization among intelligent devices form different manufacturers, which support IEEE 1588 precision time protocol, it is extremely necessary to perform IEEE 1588 protocol conformance test for these devices. After a brief introduction to IEEE C37.238-2011 standard profile, i.e., the Power System PTP Profile, a method for IEEE 1588 conformance test is proposed; the required test structure is analyzed and the testing process based on test cases is described. The detailed description on the contents of IEEE 1588 conformance test are given, and the key points in the implementation of IEEE 1588 protocol conformance test are summarized.
