Automation expertise and control technologies key to operation of new high-efficiency, low-emissions supercritical generating units by country’s largest power utility
Emerson Process Management, a global business of Emerson, has won an order from NTPC Limited to provide automation technologies and expertise for two new 800-megawatt supercritical generating units at the Darlipali Super Thermal Power Station in the Sundergarh District, Odisha, India.
The new units will help meet the energy needs of the region’s growing population. Unit 1 commissioning is expected in December 2017, with Unit 2 to follow three months later.
“Supercritical technologies boost the efficiency of coal-based electricity generation while reducing carbon and other emissions, but the high temperatures and pressures involved make them more challenging to control,” explained Dr. Amit Paithankar, managing director, Emerson Process Management, India. “Our automation specialists have proven expertise and our Ovation™ control system is in more than 300 of these complex units worldwide. We welcome this opportunity to apply that experience to these important national assets.”
Emerson project teams will engineer, install and commission Ovation systems to monitor and control each unit’s supercritical boiler and critical balance-of-plant processes and equipment. Emerson will also provide its Rosemount® Analytical online steam water analysis system and continuous emissions monitoring system, Rosemount pressure and level transmitters, and additional instrumentation.
Emerson previously worked with NTPC Limited, which is India’s largest power utility, to automate units at the Sipat, Simhadri, and Tanda power stations and is currently carrying out projects at several other sites.
“We appreciate NTPC’s ongoing confidence in our people and technologies,” said Bob Yeager, president of Emerson Process Management’s Power & Water Solutions. “Our teams will make the most of everything they’ve learned on previous projects to help NTPC meet the region’s growing demand for electricity.”
