COMTRADE录波文件格式解析及继保测试仪回放功能兼容性测试

Analysis of COMTRADE format files and compatility test of relay protection testing devices

介绍COMTRADE(电力系统暂态数据交换通用格式)的文件格式,举例分析导致COMTRADE格式录波文件仍存在兼容性问题的原因。并对继保测试仪录波回放功能进行小范围兼容性测试,发现兼容性问题是导致录波回放失真的主要原因。建议从敦促厂家规范录波文件格式和在设备选型时将兼容性检查作为考核项目,以及增加检测手段等入手,缩减兼容性问题的发生来源和机率。

In this article, the COMTRADE files format is introduced in details, and main causes are analyzed which lead to the compatility problems. A small range test has been operated to verify the replaying function of relay protection testing devices, and the result shows that the main cause is compatility problems. At the end, in order to reducing probability of compatility problems, some advices have been given including recommending device supplier to normalize COMTRADE record files, setting the eompatility check as a critical item, and increasing examining means.
