Unit of Competency UEPOPS442 - Monitor and coordinate the operation of a combined cycle gas turbine unit
Description
Employability Skills
Learning Outcomes and Application This unit involves the skills and knowledge required to simultaneously operate and monitor combined cycle power generation plant. It involves the safe and effective management of energy production to meet demand using a combined cycle gas turbine unit.Combined cycle plant typically consists of a gas turbine and associated generator, Heat Recovery Steam Generator (HRSG), steam turbine and associated generator. Combined cycle power plant uses both the gas and steam turbines together to produce more electricity from the same fuel.Competency in this unit requires the ability to plan for plant operation,operate heat recovery steam generator,operate generator and excitation system,control generation of electrical energy,coordinate unit operations,monitor system/plant,test system/plant operation,analyse system/plant faults and complete all documentation. Individuals will, in general, work as an operator, in a power generation facility.Power generation plant operators are typically trained and authorised to isolate, prepare plant and issue permits to work.No licensing, legislative or certification requirements apply to this unit at the time of publication.Note: Workplace practiceThe application of the skills and knowledge described in this unit may require a licence or training permit to practice in the workplace where work is carried out on gas and electrical installations. Additional conditions may apply under state and territory legislative and regulatory licensing requirements.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.
