Patent number: 8099942Abstract: A method of operating a power generation system is provided. The system includes a first gas turbine engine that uses 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 and secondary fuel. The method includes supplying primary fuel to at least one of the first and second engines from a common fuel source coupled to the first and second engines, and selectively operating the first engine between a first operational position and a second operational position. The first engine using only secondary fuel in the first operational position and operates using only primary fuel in the second operational position. The method includes supplying the second engine with primary fuel from the common fuel source without flaring the primary fuel.Type: GrantFiled: July 17, 2007Date of Patent: January 24, 2012Assignee: General Electric CompanyInventors: Michael Joseph Alexander, Rahul Mohan Joshi, Matthew Charles Prater, William Randolph Hurst, John Reuben Aiton
