The Hybrid Performance (HyPer) Facility at NETL Morgantown, WV, consists of a cyber-physical gas turbine/solid-oxide fuel cell hybrid, in which the fuel cell is the virtual component. A historical efficiency loss trend over a 5 year period was investigated by using a Python script to filter, align, organize, and summarize test data. Historical startup data of the Hyper Facility from years between 2012 and 2018 were aligned by setting the time equal to zero when the ignition state  changed to true. The data was then filtered to exclude deviant startup conditions. Trends and correlations within the data were plotted within varying regions of the data and analyzed by Principal Components Analysis and Discriminant Analysis. Pressure and temperature sensors at the turbine exhaust were found to correlate with timestamp; similarly, the pressure differential sensor between the turbine inlet and compressor outlet showed high correlation with efficiency.  It was identified that pressure and temperature sensors at the turbine exhaust correlated with the identified efficiency decay; it was also noted that the pressure differential sensor, PDT-158, decreased with timestamp similarly to efficiency.  In future work, it would be worthwhile to record startup data for all sensors, modify the Python script to use actual linear regression, and recreate the efficiency plot for only the old turbine performance.

POWER-ICONE - Virtual Conference

Supporting the need among researchers worldwide for additional online and multimedia content, ASME now offers the ASME Conference Video Collection. This platform will collect and provide long-term access to conference presentation videos, encompassing all technology areas within ASME's technical conference and events program. About 30,000-40,000 engineers across all mechanical engineering and related disciplines participate in ASME conferences each year. This includes authors of approximately 6,000 to 8,000 technical papers published by ASME, the majority of whom also submit video presentations for our virtual conferences. The video collection will be available as an add-on to existing product packages or as a separate subscription.
