DWY－3A远动系统可靠性分析

Analysis on the Reliability of DWY-3A Telecontrol System

本文在介绍ＤＷＹ—３Ａ远动系统ＲＴＵ、通道、主控站结构的基础上，总结分析了系统中采用的提高可靠性方法；利用状态空间法推算了主控站平均无故障时间与设备维修率的关系，提出了主控站的一种改进结构并与原有结构进行比较，最后得到了有益的结论。

This paper introduces nieasures for iniproving reliability of DWY- 3A telecontrol system, by analysing the structure of its RTU,channel and control center.For control center.the relation between individual device’s maintenance rate and the system MTBFis ca1cu1ated with the state analysis method. An improved control center structure is proposed and compared with the original system.
