Release 1.  This is the first release of this unit of competency in the UEP Electricity Supply Industry - Generation Sector Training Package Release 2.0.

This unit involves the skills and knowledge required to diagnose and repair faults in large scale wind turbine control systems.

Diagnosing and repairing faults is the process of optimising the outcomes of large scale wind turbine control systems through regular inspections and verification of operational efficiency.

Competency in this unit requires the ability to gather data, interpret data to establish hypothesis about wind turbine control system fault, repair wind turbine control system fault and record wind turbine control system fault. Individuals will, in general, work under supervision in an electrical, electronic and/or mechanical equipment repair workshop or on site.

Power generation maintenance personnel are typically trained and authorised to receive permits to work.

Licensing/Certification Information 

The application of the skills and knowledge described within this unit may require a licence/registration to practice in the workplace. Other conditions may also apply under State and Territory legislative and regulatory licencing requirements which must be confirmed prior to commencing this unit. For this unit persons must have one of the following as an entry requirement:

• Unrestricted Electrical Licence issued in an Australian State or Territory, or
