Method and system for power differential and ease of maintenance of a combined gas turbine plant

摘要

A power generation plant is provided. The power generation plant includes a first gas turbine engine (120) configured to operate using at least one of a primary fuel (110) and a secondary fuel (160). The first gas turbine engine is selectively operable 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. The power generation plant also includes at least one second gas turbine engine (130) configured to operate using at least one of a primary fuel and a secondary fuel, and a common fuel source coupled to the first and second gas turbine engines. The common fuel source is configured to supply at least one of the first and second gas turbine engines with primary fuel without flaring the primary fuel.
