RTU信息采集的分析和改进

变电站RTU装置在汇集远动信息(包括遥信和微机保护报文)的过程中，存在着遥信误发、漏发和微机保护报文异常、丢失的现象，文章对其产生原因分别进行了详细地分析，并具体提出了相应的改进措施。经维护实践证明，这些措施有力地提高了接点量遥信和微机保护报文的准确率，是行之有效的。

Analysis and improvement of RTU information collecting

In the telecontrol information collecting process of RTU in power substation (including tele-switching signal information and computer protection message), there are some problems, including the tele-switching signal was sent mistakenly, the computer protection message come forth unusually and loss. The reasons of causing these phenomena are analyzed in this paper, and the concrete improvement measures are put forward. It is proved that the feasibility and accuracy of teleswitching signal information and computer protection message are effectively improved.
