10) This relates to the competency standard unit 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. Inspection should be planned with the appropriate parties to determine access, conditions and work requirements. Wind farm control systems may include: generator excitation systems, inverter systems, speed control systems, rectifier systems, blade pitch systems, wind direction sensing systems and yaw control systems. Wind farm control systems communication systems may include: TCP/IP network, ethernet, fibre optic, wireless, fieldbus, hart protocol, profibus, internet and hard wired. Wind farm control systems may include one or a combination of: electronic systems, distributive control systems, SCADA, electrical systems, pneumatic systems, hydraulic systems, mechanical systems and PLC systems. Equipment may include: circuit boards, circuit breakers, transformers, rectifiers, inverters, pressure gauges, electric motors, control cabinets, protection equipment, transmitters, switches, temperature sensors, indicators, meters, proximity probes, fire detectors, smoke detectors and vibration detectors, fibre optic cables, Category 5 cables, wireless transmitters and receivers. Components may include: fuses, circuit breakers, timers, contactors, contacts, coils, relays, resistors, inductors, capacitors, bridge rectifiers, diodes, heat sinks, solenoids, overloads, plug in printed circuit boards, switches, plugs, cables and thermistors. Fixed wiring tests can refer to: polarity, loop impedance, insulation resistance and continuity tests. Materials may refer to: insulation tapes, heat shrink, sleeving, spiral binding, cable ties, solder, lubricants, oil, greases, sealants, lugs, connectors, terminal blocks, cable markers and identification labels. Tools, equipment and test and measurement instruments may include: multimeter, decade box, d.c., I/V standard, potentiometer, radiation meter, hand-held communicator, frequency counter, frequency generator, CRO, variac, hand tools, power tools lifting equipment and specialised test equipment. Fault find and diagnostic techniques may include: linear approach, half split rule, sensory detection/insulation/resistance and continuity test. Fault indicators may include: self test systems, DCS logs, indication lamps, alarms and flag relays. Work may be performed in service or out of service. Work completion details may include: plant and maintenance records, job cards, check sheets and on device labelling updates. Work site environment may be affected by nearby plant or processes, e.g. heat, noise, dust, oil, water height and chemicals. Isolations can refer to electrical/mechanical or other associated processes. 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. |
