Abstract
Provided herein is a method for automated control of the gas turbine fuel composition through automated modification of the ratio of fuel gas from multiple sources. The method includes providing first and second fuel sources. The method further includes sensing the operational parameters of a turbine and determining whether the operational parameters are within preset operational limits. The method also adjusting the ration of the first fuel source to the second fuel source, based on whether the operational parameters are within the preset operational limits.
Claims36
A method for automated control of a combustion turbine fuel composition through automated modification of a ratio of fuel gas, comprising:
- providing a first fuel source;
- providing a second fuel source;
- supplying fuel to a combustion turbine in a blend of fuel from the first source and second source;
- sensing the operational parameters of the gas turbine;
- determining whether the operational parameters are within preset operational limits;
- adjusting the blend of the first fuel source and the second fuel source, based on whether the operational parameters are within the preset operational limits.
A tuning system for automated control of a gas turbine fuel composition through automated modification of a ratio of fuel gas, comprising:
- operational turbine controls for operational control elements of the turbine, the turbine controls controlling at least one of turbine fuel distribution or the fuel temperature,
- a tuning controller communicating with the controls, the controller configured to tune the operation of the turbine in accordance with the following
- receiving operational data about the turbine,
- providing a hierarchy of tuning issues,
- determining whether sensed operational data is within predetermined operational limits and producing one or more indicators if said operational data is not within predetermined operational limits,
- ranking the one or more indicators to determine dominant tuning concern, and
- providing a blend of fuel to a level blend ratio controller, the blend having fuel from at least one of a first and second fuel source ratio controller, the fuel blend ratio controller adjusting the ratio of the first fuel source and the second fuel source according to the blend.
