Certain embodiments may include systems and methods that comprise a first unit controller associated with a first gas turbine and a second unit controller associated with a second gas turbine. A first unit human machine interface is coupled to the first unit controller and is operable to provide first blend information to the first unit controller. Additionally, a second unit human machine interface is coupled to the second unit controller and is operable to provide second blend information to the second unit controller. A splitter panel, coupled to the first unit controller and the second unit controller, is operable to transfer control of a plurality of common skids between the first unit controller and the second unit controller. The transfer of control may occur by toggling a plurality of relays housed in the splitter panel. A plurality of common skids is operable to provide biofuel to a plurality of injection skids. The plurality of common skids may comprise a heating skid, a filtration skid, and a pumping skid shared by the first gas turbine and the second gas turbine.

The present disclosure is directed to a method for controlling a pitch angle of a rotor blade of a wind turbine. The method includes adjusting, with an actuator, the pitch angle of the rotor blade during a start-up sequence of the wind turbine. The actuator adjusts the pitch angle of the rotor blade by rotating the rotor blade about a pitch axis relative to a hub. The method also includes determining, with a controller, a minimum pitch angle threshold of the rotor blade based on a tip speed ratio of the rotor blade. The method further includes comparing, with the controller, a current pitch angle of the rotor blade to the minimum pitch angle threshold. When the pitch angle meets the minimum pitch angle threshold, the method includes preventing, with the actuator, the pitch angle of the rotor blade from exceeding the minimum pitch angle threshold.

A method for detecting leakage at a fluid connection for a gas turbine fuel supply system is disclosed herein. The method includes closing a flow control valve at an upstream end of the fuel supply system and pressurizing the fuel supply system with a compressed medium via a compressed medium supply to a target pressure. The target pressure is less than a pressure threshold of a check valve that is disposed downstream from the compressed medium supply and upstream from a corresponding combustor of the gas turbine. The method further includes pointing a receiver portion of an ultrasonic detection device proximate to at least one tube fitting of the fuel supply system located between the flow control valve and a combustor which is fluidly coupled to the fuel supply system. Detection of an increase in sound level and/or the sound of popping at the tube fitting is indicative of a leak at the tube fitting.
