Abstract:
1. A method of operating a power generation system that includes a first gas turbine engine that operates using at least one of a primary fuel and a secondary fuel, and at least one second gas turbine engine that operates using at least one of a primary fuel and a secondary fuel, said method comprising: channeling primary fuel to a common fuel source at a controlled flow rate; supplying at least one of the first and second gas turbine engines with primary fuel from the common fuel source at a controlled flow rate, wherein the common fuel source is coupled to the first and second gas turbine engines; selectively operating the first gas turbine engine between a first operational position and a second operational position, wherein the first gas turbine engine operates using only secondary fuel in the first operational position and operates using only primary fuel in the second operational position; and supplying the second gas turbine engine with primary fuel from the common fuel source at a controlled flow rate prior to operating the first gas turbine engine in the first operational position, such that the second gas turbine engine may absorb primary fuel from the first gas turbine engine without flaring the primary fuel.
