Research Of SCADA (Supervisory Control And Data Acquisition) System In Dispatching Centre

In the dispatching center , the SCADA system is the interface of protection, monitoring, communication settings and substation operator. It also must send data between substation and distant dispatchers office. So, it is very important in the substation integrated automation system.This paper analyses the SCADA system particularly, and introduces the SCADA software iES-500 which is used in the Dispatching center. Especially,This paper introduces the communication and data systems.The SCADA data base is so larger that the channel is easy to be blocked. So, dispatchers can not to deal with the faults rightly and quckly. Using the measure of merging signals can optimizing the SCADA system. No adding the hardware and update the software .using this measure, we can make the channel well. It makes big value , and it rises the efficiency of the dispatcher's supervisory control.
