This PI System plugin module is useful for identifying loss of efficiency or other turbine problems. It provides real-time turbine section efficiencies and power output and tracks these parameters.
Real time calculations include actual and expected efficiencies of each individual steam turbine, steam power extracted from each individual turbine, and electrical and mechanical losses. All steam turbine leakages are calculated and accounted for.
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.
