SAS Introduction

• An efficient way of automating the

management and control of Sub-Station

Equipments

• All activities and process are standardized

( protocols 61850, TCP/IP)

• Control is on-site or remote

• Sufficient data logs and history to forecast

faults

What

Empowering Lives 3

What is SAS?

• Automation of Substation Equipments for Control and

Monitoring

• Open platform products- No monopoly and dependency

on one company

• SAS includes integration of various Intelligent Electronic

Devices (IED’s) like protective relays and multi-function

meters

• With SAS , data management facilities like process

monitoring, supervisory control, alarming, reporting and

data archiving is achieved

• Implemented on the latest IEC61850 protocol standards.

SAS Features

• Easiness of Operation

• Integrated protection, control, monitoring and

automation system

• Open and modular approach with scalable

architecture

• Bay and station level communication based on

open/standard protocols

• Redundancy architecture ensures 99.99%

uptime and availability

• Fiber optic infrastructure for intra-communication

SAS Features

• Powerful graphical user interface

• Complete solution for new and existing

substations for utility and industrial customers

• Energy accounting

• Reduced downtime by utilizing maintenance

history for preventive maintenance

• Implementation of IT, hence manpower is better

utilized

• Report generation for management decisions

Substation Integration and Automation Levels

Utility Enterprise Application (Billing, CRM, ERP, MIS)

Substation Automation Application

IED Integration

IED Implementation

Power System Equipments (Transformers, Breakers ,etc)


SAS Integration Levels

Empowering Lives

• Process level: Interfacing of Equipment to IED

– Process interface CT, VT, Trip coil, etc

• Bay level: Interfacing IED to Bay control units

• Station level: Interfacing BCU to Gateway,

Human Machine Interface(HMI- Software)

• Network level: Interfacing of Ethernet switch,

modem, routers, station computer, server etc.

SAS for Distribution

• Is SAS for Transmission only ?

– Revenue Loss, Shutdown

• Smart Grid is converging to Smart Home

• Activity Based Tariff is converging to Device Based Tariff

• Energy Management Systems (EMS)

• SAS will have ability to integrate to these systems

Empowering Lives

SAS and SCADA

• Software (HMI) (Supervisory Control and

Data Acquisition)– SCADA, HMI, Operating Systems and Relay Interface Software's

Relay Manufacturer SCADA Application
