Per government estimates, power produced by the plant is priced at about 20 rupees or $0.18/kWh.

Distributed control systems are powerful assets for new and modernized power plants. Thanks to three product generations of technology innovations, these systems now provide new benefits — including improved O&M efficiency, greater plant design flexibility, and improved process control and asset reliability — that help competitive plants advance in the game.

By now, most electric industry participants are aware of the mandatory reliability standards required by the Energy Policy Act of 2005 and managed by the North American Electric Reliability Corp. (NERC). Bulk-power system users, owners, and operators (known as NERC registered entities) are responsible for complying with the set of standards that are applicable to their operations in their specific region. Compliance is monitored by the NERC regions (Texas Regional Entity, Western Electric Coordinating Council, Reliability First Corp., Midwest Reliability Organization, SERC Reliability Corp., Florida Reliability Coordinating Council, Northeast Power Coordinating Council, and Southwest Power Pool) through spot checks, self-certifications, audits, and investigations.

Over the past decade, power plant control systems have evolved from DCS-centered platforms with proprietary software, to open systems using industry standard hardware and software, and then to totally integrated plant automation systems with almost unlimited connectivity and the ability to interrogate field instruments from many different manufacturers. What’s next?

Nearly 10% of boilers and pressure vessels inspected in the second quarter of 2008 were slapped with violations, which means that the violations put workers and equipment in danger, according to a quarterly report released by the National Board of Boiler and Pressure Vessel Inspectors.

Wireless technology is a mostly untapped resource in the power generation industry that can have a significant impact on the way business is done. It enables a greater degree of connectivity among devices for enhanced monitoring and asset utilization and has led to the development of new applications that improve productivity, uptime, and overall business performance.

Wear and leakage are common maintenance problems that result in pump discharge pressure dropping below optimum levels and reduced pump efficiency. Converting pumps to mechanical seals eliminates fretting or grooving of the shaft and provides for easier pump maintenance. By converting to mechanical seals, a plant also avoids incurring expenses associated with the replacement of sleeves and shafts.

Modern wireless systems improve productivity, monitoring activities, and safety at power plants by enabling the right people to be at the right place at the right time. Wireless technology can put hard-to-access process and asset information at your fingertips, wherever you are, to enable more accurate and timely decisions.
