Public Switched Telecom Network

• The only source at that time
• Dependent on service provider
• Costlier

PLCC

• Dedicated & safe
• Part of Utilities own transmission

network

• No dependence on

service provider

• Ruled for years
• Now digital PLCC,

but same core technology

• Frequency congestion
• Limited band width

– Restricted data transmission

GETCO Experience

14:23

HF Radio

• Useful for long distance
• Disaster Management

(Massive earthquake in Kutch)

• Requires license

VHF

• Helped in natural calamities

(Massive earthquake in Kutch)

• Open mode
• No network jam
• No dependence on

service provider

• Simultaneous contact to many

users

• Very useful in Distribution System

for load management

• Requires license
• Up to limited distance

GETCO Experience

14:23

Micro waves

• Relatively low cost
• Wide bandwidth
• Requires License
• Requires Line of sight
• Weather dependent

Satellite Phone

• Disaster Management

(Massive earthquake in Kutch and flood in Surat)

• Useful for long distance
• Requires License
• Costlier

Leased copper lines

• Wide bandwidth
• More reliable
• Dependent on service provider

3rd Generation Fiber Optics - FO cables in Ground wire OPGW

• No limitation in band-width –

huge transmission capacity

• Part of Transmission line -

Utilities own network

• Immune to interference
• No dependence on service provider
• Provides sufficient reserve capacity

to accommodate future expansion

30

GETCO Telecom Plan and Strategy

• Phasing out 1st & 2nd generation with 3rd generation technologies
• Installing OPGW on all new 400KV lines for Communication,

Protection, Control and SCADA (Digital Sub stations).

• Installing OPGW on strategic transmission network to provide

business opportunities.

• Developing communication network for WAMS
• Ownership basis
• Hiring basis.
• Going for GPRS connectivity for remote ABT meter reading.
• Opportunities from the transmission assets & business (consolidating

transmission assets into business units)

• Offering fiber and bandwidth on lease basis

Expectations from the telecom solution providers

• More manufacturers and suppliers should participate.
• It must be scalable.
• Modular design.
• IEC 61850 based Tele protection unit.
• Inter operability.
• Cost Effective
