This PI System plugin module simplifies the identification of reductions in turbine efficiency and other turbine performance issues.
It calculates actual and expected efficiencies of each individual steam turbine, steam power extracted from each individual turbine, and electrical and mechanical losses in real time. It also calculates and accounts for turbine leakages.
Formulations are based upon ASME A Method for Predicting the Performance of Steam Turbine Generators (by R.C. Spencer, K.C. Cotton, C.N. Cannon). Calculations are in accordance with ASME PTC 6/6s and utilize properties of water and steam calculated in accordance with the ASME 1997 formulations.
