MODELLING PROBABILISTIC CONTROL IN GAS TURBINE TUNING FOR POWER OUTPUT-EMISSIONS PARAMETERS, RELATED CONTROL SYSTEMS, COMPUTER PROGRAM PRODUCTS AND METHODS

摘要

Various embodiments include a system (802) having: at least one computing device (814) configured to tune a set of gas turbines (GTs) (10) by performing actions including: commanding each GT (10) in the set of GTs (10) to a base load level, based upon a measured ambient condition for each GT (10); commanding each GT (10) in the set of GTs (10) to adjust a respective power output to match a scaled power output value equal to a fraction of a difference between the respective power output and a nominal power output value, and measuring an actual emissions value for each GT (10) during the adjusting of the respective power output; and adjusting an operating condition of each GT (10) in the set of GTs (10) based upon a difference between the respective measured actual emissions value, a nominal emissions value at the ambient condition and a nominal emissions value at the ambient condition.
