Performance Monitoring
Power plant efficiency is critical to compete in the current power generation market. The demands in power plant efficiency, minimum and maximum loads, power plant start up and shutdown times, plant flexibility are critical for the financial performance of power plants. It is critical that plant operators select the key power plant efficiency parameters to evaluate.
Power plant output is one of the most important and critical parameters of an overall power plant efficiency evaluation. Once power plant electrical output has been determined, it can be corrected to reference conditions to provide a comparison of current plant power output to rated output. This is very important so that contract guarantees can be confirmed and/or changes in power plant efficiency can be tracked over time.
For example, to determine the combined cycle performance several operational parameters need to be considered to estimate properly the corrected combined cycle performance in terms of electrical output.
Since this parameter is intimately tied to the revenue generated by the plant, high precision measurements are required in order to ensure the highest accuracy power plant efficiency.
