Abstract
A system () and method of modifying a combined cycle power generation system (). In one embodiment of the invention an existing system includes one or more first gas turbines, one or more first steam turbines, and one or more heat recovery steam generators (HRSGs). An exemplary method includes providing at least one second gas turbine of greater operating efficiency than each of the one or more first gas turbines and connecting at least one existing HRSG to receive exhaust output from the second gas turbine to generate steam. Also according to the invention a path is provided for mixing steam exiting a high pressure steam turbine with steam generated in a low pressure HRSG to route such mixed steam through a reheat section of a high temperature, high pressure HRSG so that reheated mixed steam exiting the reheat section can be routed into a low pressure steam turbine.
