Abstract
Abstract—“Supervisory control and data acquisition (SCADA)
system” is universally accepted means of control for electrical
substation which involves continual real time monitoring
applicable to generation, transmission and distribution systems.
The heart of SCADA lies in the functioning of Remote Terminal
Units (RTUs) which collects analog and status telemetry data
from field devices and also communicates command signals to
them. The inclusion of automation in electrical substation has
resulted in a string of advantages including visibility of network
operation, flexibility of controls, real time accurate and consistent
data, statistical data archiving, faster fault identification, isolation
and system restoration. Complex design of SCADA systems
involve accurate matching of protocols and communication
parameters between connecting devices. This paper aims at
establishing a basic understanding of SCADA components,
communication protocols and architectures, standards employed
and the security risks involved in such systems.
