accessories. The master station HMI is linked via RTU and SCG
over Ethernet LAN / VSAT to all the IEDs having fibre optic as
communication medium and with multi-function meters having
twisted pair RS485 cable as communication medium.

SYSTEM COMPONENTS
Operator's Station
The SCADA system has distributed computing and networking
facilities using client-server architecture, Ethernet & TCP/IP
network protocol. It consists of a Operator cum Engineer
workstation for dialogue between operator/ Engineer and the
system through Normal Operator Commands (non-privileged) as
well as privileged commands. The Normal Operator Commands
include commands for display of single line diagram, trends,
alarms, alarm acknowledgment, viewing of instantaneous and
historical values of parameters. The privileged commands will
require logging in via a password mechanism to avoid unauthorized
access and are used for system configuration and reconfiguration
by engineers.
Ø32 bit PCs as workstations/servers
ØIndustrial Servers
Ø64 bit server (N/W layer)
ØOperating System: Windows NT/2000/XP
ØDatabase: Oracle or MySQL Server
The Operator's Station is the key human machine interface within a
substation. It acquires, processes, displays and records all the
information received by devices on bay level and transmits
operators' instructions to the devices on bay level to fulfill the
monitoring, control and administration on all the equipment in the
substation while multiple application functions are integrated in
the station.

SCADA FEATURES
HMI Features:
Single Line Drawing
The Server is the center where the data of many sub-stations are
acquired, processed, stored and transmitted. It also stores all types
of historical data.
The main functions of the Protection Relay Engineer's Workstation
include parameterizations of protective equipment and evaluation
of fault wave records, working status, fault information and
operating information, vector analysis of fault wave records,
harmonic analysis of wave record, impedance analysis of wave
records and ranging of fault wave record, etc.
The system provides an economical way of delivering locally or
remotely metering, monitoring, control, protection and recording
functions to the different users in utilities and industries. This
system is based on modern off-the-shelf technology and industry
standard communication and browsing tools.
The HMI features provide for an easy and efficient user interaction
thus enabling effective control and monitoring of the various
systems:
The single line drawing (SLD) gives the complete overview of the
substation. It contains details about the Dynamic Busbar colouring
feature, Status of switches and the details of the primary and
secondary equipment and display of metering parameters.

Reporting
There is a strong MIS reporting software integrated to the HMI software. The reporting system allows the user to retrieve different kinds of
reports according to the different functional groups in the organization. The data retrieval is time-bound at the user specified frequency
intervals. Several reporting options are available to meet the customer requirements:
ØLog Report
ØEnergy Report
ØPower Consumption Report
ØEnergy Accounting
ØEnergy Loss Analysis
ØPeak load of the system·

SUBSTATION COMMUNICATION GATEWAY (SCG)
Description
Substation Communication Gateway (SCG) acquires data from the
numerical relays, digital multifunction meters and field
equipment and aids in data management like real-time process
monitoring, alarming, reporting and data archiving. It Polls and
Collects meter data, status, event and fault report data from
intelligent electronic devices (IEDs) installed using standard
protocols like IEC-60870-5-103, IEC 61850 and MODBUS
TCP/IP and makes it available to local HMI and control centers
using LAN, WAN connections. The SCG interfaces the information
from field with the PC and also provides Remote Connectivity over
Ethernet LAN or over Modem Dial up/ Leased line connection for
remote monitoring.
In addition, we also have Power System Monitoring Recorders,
TESLA series that record data simultaneously in three time
domains: high speed transient fault (seconds), low speed dynamic
swing (minutes), continuous trend (10 second to 1 hour intervals)
and can be easily integrated with the existing SCADA solutions.
