Elements and Performance Criteria
- Plan and Prepare Work
- Occupational Health and Safety standards, statutory requirements, relevant Australian standards, codes of practice, manufacturers’ specifications, environmental requirements and enterprise procedures are identified, applied and monitored throughout the work procedure.
- Work, plant and type of start requirements are identified from relevant personnel and documentation.
- Turbine running-up and loading schedules are ascertained from relevant documentation and in accordance with enterprise/site requirements.
- Localised plant and auxiliary equipment inspections, pre-operational tests and field preparation for service are carried out in accordance with manufacturer's and enterprise/site procedures.
- Plant and auxiliary equipment operational pre-requisites are established in accordance with manufacturer and enterprise/site procedures.
- Sequence for recommissioning of plant and auxiliary equipment is determined to suit existing circumstances in accordance with enterprise/site requirements.
- Where appropriate, the team’s and individual’s roles and responsibilities within the team are identified, and where required, assist in the provision of on-the-job training.
- Work is planned in detail including sequencing and prioritising and considerations made, where appropriate, for the maintenance of plant security and capacity in accordance with system/site requirements.
- Coordination requirements, including requests for isolations where appropriate, are resolved with others involved, affected or required by the work.
- Operate and Monitor hydro plant
- Test plant and auxiliary equipment operation
- Analyse plant and auxiliary equipment faults.

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 turbines; turbines with underslung pumps; inlet valve, inlet bypass valve, scroll case and draft tube, relief valve, wicket gates or spear valve, gate swing ring or spear actuator, runner, turbine bearing; reversible turbines; auxiliary plant and equipment, including batteries, chargers, governor oil pumps, auxiliary generators, standby generators, air compressors, transformer and bearing cooling water pumps, pressure reducing valves, dewatering and sump pumps, seal water filters, bearing oil coolers, oil and water separators, fire detection and protection equipment; governor and associated hydraulic circuits; generator and auxiliary plant including main exciter, commutator, pilot exciter, voltage regulator, synchronising equipment, cooling systems, lube oil systems, seal systems, brake systems; computer with equipment control functions; supervisory, alarm and control equipment; electrical motors, fans and pumps; electrical supply and distribution systems; valves and dampers (electric, hydraulic, pneumatic and manual); lubrication and oil conditioning systems; static/rotating rectifiers; brush gear and slipring fire protection equipment; sliprings and commutators; AVR/AER; heat exchangers, filters and strainers; generators; transformers; water drainage systems; and environmental protective systems.Safety standards may include relevant sections of Occupational Health and Safety legislation, enterprise safety rules, relevant state and federal legislation, national standards for plant and Australian standards.Information and documentation sources may include verbal or written communications; enterprise safety rules documentation; enterprise operating instructions; dedicated computer equipment; enterprise/site standing and operating instructions; enterprise log books; manufacturer operation and maintenance manuals; and equipment and alarm manuals.Technical and operational indicators may include stimuli (audio, smell, touch, visual), remote or local indicators and recorders, computers and alarms (visible and or audible).Tests may include motor direction checks, stand-by plant “cut-in” tests, relief valves operation tests, overspeed tests, main inlet valves/guide vanes timing tests, load rejection tests, governor damping tests and phrase rotation tests.Communications may be by means of telephone, two way radio, pager, computer (electronic mail) and operating logs (written or verbal).Appropriate personnel to consult, give or receive direction may include, supervisor/team leader or equivalent, engineering officer/hydro maintenance office or equivalent, technical and engineering officers or equivalent, contractor staff, maintenance staff, applicable water control authority or equivalent and “transgrid” operator or equivalent.Test, fault finding and operating tools may include low and high voltage testers, proving dead equipment, powered or non-powered hand tools.Operating environment may be remote from plant, aided by indicators and monitors, during inclement or otherwise harsh weather conditions, in wet/noisy/dusty/hot areas, during night periods or locally aided by visual and audible indicators.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. |
