引言目前 ,电力系统所配置的录波装置种类繁多 ,远传系统采用的规约不尽相同 ,有的老设备甚至采用生产厂家自定义的通信规约 ,这给调度中心的统一管理带来了很大的困难。近几年开发的监录装置都纷纷采用了电力部于 1997年颁布的《ＤＬ/Ｔ 6 34 1997基本远动任务配套标准 (传输规约 )》。该标准是非等效采用国际标准ＩＥＣ 6 0 870 5 10 1[1] ,其内容与国际标准相一致。ＩＥＣ 6 0 870 5 10 1主要用于远动设备和调度之间传输遥测、遥信、遥控、遥调及保护定值、录波数据等。该协议传输数据容量是ＣＤＴ协议的数倍 ,已经作为中国电力行业… | | |  推荐 CAJ下载  PDF下载 | | | CAJViewer7.0阅读器支持所有CNKI文件格式，AdobeReader仅支持PDF格式 | | | | Realizing remote data transmission of G?T unit state detection and record system with multithreading on VC ++ | | | JIE Ping;ZHANG Zhe;JIANG Xiong jie;YANG Jun;JIANG Wei liang (Huazhong University of Science and Technology;Wuhan 430074;China) | | | In order to meet the demand of power plant automation development,especially the demand of condition based maintenance,the remote data transmission function of the state detection and record system for generator transformer unit has to be enhanced.According to the companion standard for basic tele control tasks of electric power system,IEC 60870?5?101 protocol, the multithreading technique under NT environment is adopted to realize the remote data transmission of the G?T state detection and record system.By separating the data acquisition sub thread and the data processing sub thread from the main thread,the real time performance and reliability of the remote data transmission can be greatly improved.The SW design concept of using VC++'s MFC in multithreading programming and the application of IEC 60870?5?101 protocol are emphasized.
