COMMUNICATION AT NTPC
NTPC has deployed a comprehensive Communication Network Setup
and Computing infrastructure covering all its offices at Corporate
Center and Regional Headquarters, Plant/Projects and Coal Mining
including NTPC Subsidiaries and Joint Ventures. With a dedicated
Satellite transponder allocation to NTPC since 1989, a Satcom/
Telecommunication network set-up was established that includes
VSATs, Microwave/ Canopy and Terrestrial links for providing
Voice, Fax and Data Communication needs.
The Satcom Network has been implemented with Central Hub Station
at Sector 24, Noida and in Star and Mesh Topology, using PAMA and
DAMA technology that covers 32 locations operating at 512Kbps to
2Mbps.
SATELLITE COMMUNICATION
SETUP AT NTPC
Satellite communication is one particular example of wireless
communication systems. Modern satellites can receive and transmit
hundreds of signals at the same time, from simple digital data to
complex television programs.
In NTPC, an Indian communication satellite GSAT 10 geostationary
satellite is being used. It has 12 KU Band, 12 C Band and 6 lower
extended c band transponders, and included a navigation payload to
augment GAGAN

TELEMETRY AND DATA HANDLING
NEW TECHNOLOGY
To meet the challenges of fulfilling India’s electricity demands at affordable
cost with minimum environmental impact, Company has drawn a long term
Technology Roadmap up to 2032.
The technology roadmap envisages development, adoption and promotion of
safe, efficient and clean technologies for entire value chain of power
generation business.
NTPC is planning to set up coal fired units with
Ultra supercritical parameters targeting efficiency comparable to best
available technology in the world.
It is planning to establish integrated gasification combined
ULTRA SUPERCRITICAL TECHNIQUE
• The thermodynamic efficiency of a Rankine steam cycle increases with
increasing temperature and pressure of the superheated steam entering the
turbine
• It is possible to increase further the mean temperature of heat addition by
taking back partially expanded and reduced temperature steam from the
turbine to the boiler, reheating it, and reintroducing it to the turbine.
• In the usual designation of steam parameters the second and third
temperature refers to single and double reheat, e.g.
309bar/594°/594°/594°C, respectively.
• As steam pressure and superheat temperature are increased above 221 bar
(3208 psi) and 374.5ºC (706ºF) the steam becomes supercritical (SC); it
does not produce a two phase mixture of water and steam as in subcritical
steam, but instead undergoes a gradual transition from water to vapor with
corresponding changes in physical properties.
• Ultra- supercritical (USC) steam generally refers to supercritical steam
at more than (1100ºF) temperature. EPRI’s terminology for 1300ºF and
1400ºF plants is Advanced Ultra Supercritical (AUSC).
INTEGRATED GASIFICATION
COMBINED
• Gasification-based technologies use partial oxidation of coal with oxygen as
the oxidant to produce a synthesis gas (syngas) consisting mainly of CO and
H2.
• The gas is cleaned to remove contaminants before it is used as fuel in a
combustion turbine.
• The exhaust gas of the gas turbine raises steam in a heat recovery steam
generator(HRSG) for a steam turbine-electric generator set..
• The combined cycle efficiency improves through the reduced effect of the
steam condenser’s heat loss. As with combustion technologies, higher
efficiency results in lower emissions per MWh.
CHALLENGES IN TECHNOLOGY
• Development of high temperature creep resistant alloy steels.
• Turbine material development
• Alternative boiler technology for gasification cycles. like FBCs etc.,
• Advanced controls & Instrumentation
• Stringent Boiler Water Quality Control
• Transfer of Technology (TOT)
HAZOPHAZOP stands for Hazard and Operability. It is a method of study for
identifying hazards and operability problems in many operational situations
ranging from chemicals and fuels processing through to electrical and
machinery systems. It is also finding applications in the planning of
operational activities such as emergency response and disaster
management.
ASH UTILIZATION
• Research has shown that the quality of fly ash produced at NTPC’s
power stations is extremely good with respect to fineness, low unburnt
carbon.
• The fly ash generated at NTPC stations is ideal for use in the
manufacture of cement, concrete, concrete products, cellular concrete
products, bricks/blocks/ tiles etc.
• Over the years, ash consumption level has reached from meagre 0.3
million ton in 1991 - 1992 to 30 million tons in 2012-13.
• The important areas for this utilisation are cement industry, bricks
industry, road embankment, mine filling, land development and ash
dyke raising. It is also a source of micro and macro-nutrients in
agriculture.
CONCLUSION
• To make sure we have plenty of energy in the future, it's up to all of us to
use energy wisely.
• We must all conserve energy and use it efficiently. It's also up to those
who will create the new energy technologies of the future.
• All energy sources have an impact on the environment. Concerns about
the greenhouse effect and global warming, air pollution, and energy
security have led to increasing interest and more development in
renewable energy sources such as solar and wind.
• NTPC is make effort for perfect greener source of energy to improve the
environment and reduce dependence on oil and other fossil fuels.
Imagination is more important than knowledge, for knowledge islimited, whereas imagination embraces the entire world – stimulatingprogress, giving birth to evolution.
