This PI System plugin module provides real-time compressor efficiencies, expected generator capacity, and expected heat rates based upon compressor inlet temperature and humidity.
This information can be useful in determining loss of turbine efficiency or other problems. Curves are customizable and can be easily adjusted anytime afterward. Expected values calculations require the availability of appropriate curves (from the manufacturer or actual historical data).
The tool makes it easy to identify problems with turbine performance early. It also provides corrected load and heat rate at base load which provides the best indication of turbine condition since all environmental factors are removed and turbine performance is measured at the same base conditions at all times so any step change in the performance is easily detected.
The visualization module features real-time heat rates of each gas turbine as well as both net and gross heat rates of the combined cycle plant. This information can be useful in determining loss of turbine efficiency or other problems.
