Fleetwide Monitoring (FWM) is the implementation of applications for monitoring, maintaining and optimizing generation (and other) assets from a centralized location (Hussey, 2010). Fundamentally, FWM involves monitoring assets within a fleet of assets to detect operational and equipment problems earlier enough to mitigate damage, manage risk, identify performance problems, and manage business and market conditions or risks. A key part of FWM involves the use of advanced online monitoring technologies developed in the 1990s and 2000s and first applied in aerospace, transportation, and petrochemical applications. The goal of FWM is intelligent top-down approach to plant maintenance and scheduling. The goal is accomplished by the move toward centralized monitoring and diagnostic centers, the integration of advanced monitoring applications, and continued use of existing monitoring and maintenance technologies. The efforts supporting the goal will be facilitated by emerging standards supporting interoperability of equipment and technologies from multiple vendors.

The Power of Flexibility: Turbine Inlet Air Chilling Benefits
Gas turbines are constant volume air intake machines; consequently, air mass flow and resultant power output fall as ambient temperatures rise and air density falls. The purpose of Turbine Inlet Air Chilling (TIAC) is to restore the power output of a combustion turbine at elevated ambient temperatures to its rated capacity or better. As the critical 'operating system' of the TIAC enhancement, the control technology also plays an integral role in maximizing operational flexibility.

Fully Automating HRSG Feedwater Pumps
Modern distributed control system platforms can provide many tools to capture best operating practices and automate them. This case study shows the steps taken to automate a hypothetical simplified feedwater pump system for a combined-cycle power plant. It describes a combination of control automation strategies and human-machine interface techniques designed to increase the overall level of automation while improving ease of use.
