Additional gas turbine power output by up to 23.5 MW at low ambient temperatures
Enhanced operational flexibility at low ambient temperatures especially in combination with power augmentation solutions (e.g. Wet Compression)
General Product Information
Due to the Si3D upgrade and the common use of Power AuGmentation (PAG), inlet cooling or WetC the current gas turbine power limits are often already reached at ISO and/or even at warm ambient conditions. Once the power limit is reached, the power limit controller closes the IGVs to limit the gas turbine load to its maximum value, thus reducing available GT power output and efficiency.
The Power Limit Increase (PLI) upgrade is increasing the engine’s rating, which allows operating the engine at a higher maximum GT power output (up to 16 %).
