Description

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 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 HRSG,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 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.
