10) This relates to the unit of competency as a whole providing the range of contexts and conditions to which the Performance Criteria apply. It allows for different work environments and situations that will affect performance.Plant and equipment may include turbine and auxiliary plant turbine by-pass system plant; turbine lubrication and power/control oil systems; condensate and feedwater system plant to boiler economiser inlet valve; condensate polishing plant; high and low pressure heating systems; steam condensing and cooling systems; condenser vacuum raising equipment; turbine gland sealing equipment; condenser cooling water systems plant; boiler feedwater de-aerating equipment; condensate and feedwater chemical treatment equipment; electric motors a.c. and d.c.; electricity distribution systems a.c. and d.c.; diesel engine driven auxiliary plant; station water distribution systems; hydraulic oil system; pumps; compressed air systems; computers with equipment control functions; supervisory, alarm, protection and control equipment; and pumps.Safety standards may include relevant sections of Occupational Health and Safety legislation, enterprise safety rules, Australian standards, national standards for plant and relevant state and federal legislation.Information and documentation sources may include verbal or written communications; enterprise safety rules documentation; enterprise operating instructions; manufacturer operational and maintenance manuals; equipment and alarm manuals, enterprise log books, dedicated computer equipment, enterprise standing instructions and plant notes.Technical and operational indicators may include stimuli (audio, smell, touch, visual), remote or local indicators and recorders, computers and alarms (visible and/or audible).Communications may be by means of telephone, two way radio, pager, computer (electronic mail) and operating log (written or verbal).Tests may include motor direction checks, stand-by plant “cut-in” tests, pre and post shut-down tests, valves operating checks, alarm and protection tests and turbine overspeed testsAppropriate personnel to consult, give or receive direction may include supervisor/team leader or equivalent; technical and engineering officers or equivalent; maintenance staff; power plant operations personnel or equivalent.Operating environment may be remote from plant and equipment being operated; where operation is assisted by remote indicators of plant status and other parameters monitored; in wet/noisy/dusty/hot areas; during night periods; and during inclement or otherwise harsh weather conditions.Unit operations may include emergency shut down; turbine shutdown, with or without turbine bypass, or by using forced cooling procedures.Faults and abnormal operating conditions may include loss of a major auxiliary; turbine water ingress; excessively high turbine and turbine valves heating/cooling rates/differentials; high condenser vacuum; condenser tube leak; high dissolved oxygen, conductivity; high turbine bearing temperatures/ vibration; high/low bearing oil temperature; loss of turbine bearing oil flow/pressure; low/high pressure heaters malfunctions; turbine bypass system malfunctions; actuator/valve mechanical/electrical faults/failure; failed field devices; and turbine protection.Generic terms are used throughout this Training Package for vocational standard shall be regarded as part of the Range Statement in which competency is demonstrated. The definition of these and other terms are given in Section 2.1 Preliminary Information and Glossaries. |
