Synopsis

 - an automatic system seeking for ideal operations of the entire electrical facilities at a substation.
 - by using an Information Technology (IT), enhancing the dependability of facilities with the entire analysis and treatment like watch of breaker condition and tap control of a transformer. 

Composition of the System

HMI  (Human man interface)
 via CSD, providing the operator with the entire information about electrical facilities and transmitting control order. 

CSD (Comunication Service Device) 
by receiving the entire operation information from RTU and others, supplying the information to upper-level system and transmitting upper-level information RTU and others. 

RTU (Remote Terminal Unit) 
sending and receiving the entire information to and from CSD, watching and controlling thefield facilities. 
 

Major Composition
