Abstract:
A control system for mitigating loads on a wind turbine comprising a plurality of blades in yaw error events includes a yaw error calculation unit for calculating a yaw error of the wind turbine, a pitch angle reference command calculation unit for calculating a plurality of pitch angle reference commands respectively corresponding to the plurality of blades at least based on the calculated yaw error, and a controller for producing a plurality of pitch commands at least based on the plurality of pitch angle reference commands, to respectively regulate the pitch angles of the plurality of blades.
Abstract:
A system includes an emissions control system. The emissions control system includes a processor programmed to receive one or more selective catalytic reduction (SCR) operating conditions for an SCR system. The SCR system is included in an aftertreatment system for an exhaust stream. The processor is also programmed to receive one or more gas turbine operating conditions for a gas turbine engine. The gas turbine engine is configured to direct the exhaust stream into the aftertreatment system. The processor is further programmed to derive a NH3 flow to the SCR system based on an SCR model and the one or more SCR operating conditions, to derive a NO/NOx ratio, and to derive a fuel split for the gas turbine engine based on the NH3 flow, the NO/NOx ratio, or a combination thereof.
