Emerson to modernise NTPC's Tanda TPS
A Business Correspondent
Emerson Process Management, headquartered in Pittsburgh,
Pennsylvania, USA, has announced it has been selected by NTPC Ltd to modernise
obsolete controls at the Tanda thermal power station, a 4x110 mw plant located
in Ambedkar Nagar in Uttar Pradesh, a company statement revealed. Emerson is
installing its Ovation expert control system at all four units of the coal-fired
power plant as part of a comprehensive renovation and maintenance project.
Emerson's local India Engineering Centre is designing, engineering and
supervising the project.
A noteworthy challenge for the control system aspect of the project was the
timeframe required for Unit 3 - the first unit slated for modernisation. Emerson
received the contract for Unit 3 after the previous vendor was unable to meet
the original schedule. The control system installation and unit commissioning
needed to take place during a 90-day scheduled outage, which began in the last
week of March 2008. A mere three months after contract award, Emerson was able
to complete the project during a specified 70-day window within the outage.
At all four Tanda units, the Ovation system will monitor and control the burner
management system (BMS) and furnace safeguard supervisory system (FSSS). The
Ovation system, designed to meet the specific challenges of the power generation
industry, will also interface to the existing Bhel boiler and turbine controls.
In all, the Ovation system will manage 10,000 I/O points (2,500 points per
unit). The contract also calls for Emerson to supply a total of 40 Ovation
redundant controllers (10 per unit) and 36 workstations (nine per unit).
Emerson Process Management, an Emerson business, helps businesses automate their
production, processing and distribution in the power, water and wastewater
treatment, metals and mining, chemical, oil and gas, refining, pulp and paper,
food and beverage, pharmaceutical, and other industries. The Pittsburgh-based
company develops plant-wide process control solutions for the power generation,
water treatment and wastewater industries.
