    Title Demonstrate knowledge of the fundamentals of electricity generation

    in New Zealand

    Level 3 Credits 3

Purpose People credited with this unit standard are able to: demonstrate

    knowledge of the principles of electricity generation; and the

    types of electricity generation in New Zealand.

Classification Electricity Supply > Electricity Supply - Core Skills

Available grade Achieved

Explanatory notes

    1 This unit standard is intended for, but not restricted to, workplace assessment. The

    range statements across the unit standard can be applied according to industry

    specific equipment, procedures and processes.

    2 Performance and work practices in relation to the outcomes and evidence

    requirements must comply with all current legislation, especially the Electricity Act

    1992, and any regulations and codes of practice recognised under that statute; the

    Health and Safety in Employment Act 1992; and the Resource Management Act

    1991. Electricity supply industry codes of practice and documented industry

    procedures include the current version of the Safety Manual Electricity Industry

     A full list of current (SM-EI) (Wellington: Electricity Engineers’ Association).

    legislation and industry codes is available from the Electricity Supply Industry

    Training Organisation, PO Box 1245, Waikato Mail Centre, Hamilton 3240.

3 The phrase in accordance with industry requirements is implicit in all outcomes and

    evidence requirements in this unit standard.

    4 Industry requirements include all industry and workplace documented policies,

    procedures, specifications, and business and quality management relevant to the

    workplace where assessment is carried out.

Outcomes and evidence requirements

Outcome 1

    Demonstrate knowledge of the principles of electricity generation.

    Range conservation of energy, magnetic field and current relationships.

Evidence requirements

    1.1 The effect of current carrying conductor is explained in terms of magnetic field

    present around conductor.

    1.2 The effect of passing current through conductor in magnetic field is explained in

    terms of force moving a conductor across field flux lines.

    1.3 The effect on conductor forced through magnetic field is explained in terms of

    current induced in conductor.

    1.4 The concept of electromagnetic fields is explained in terms of magnetic field

    effect of conductor coil.

    1.5 Simple AC generation by field rotation is explained in terms of rotating field and

    electromagnetic force induced in stator winding.

    1.6 Commutation and DC generation are explained in terms of field,

    electromagnetic force induced in rotating winding, commutator and brushes to

    provide unidirectional output.

    1.7 The effect on the generated electromotive force of varying the current in the

    electromagnetic field coils in a generator is outlined in terms of flux increased,

    induced voltage increased.

    1.8 The effects of balance and imbalance between generator power output and load

    power consumption are explained in terms of rotational speed constant,

    increases or decreases.

    1.9 The concept of an infinite busbar is explained in terms of constant system

    frequency and voltage.

    1.10 The effects of varying the magnetic field and generated power with generator

    connected to infinite busbar are explained in terms of current leads or lags

    system voltage, generator accepts greater or lesser load.

    1.11 The concepts of single phase and three phase generation are explained in

    terms of single set of waveforms, three sets of waveforms and 120º

    displacement.

Outcome 2

    Demonstrate knowledge of the types of electricity generation in New Zealand.

    Range hydro, thermal, geothermal, combined cycle, co-generation, wind.

Evidence requirements

    2.1 The concept of hydro electricity generation is explained in terms of fuel source

    and characteristics, generation system, plant and equipment.

    2.2 The concept of thermal electricity generation is explained in terms of fuel source

    and characteristics, generation system, plant and equipment.

    2.3 The concept of geothermal electricity generation is explained in terms of fuel

    source and characteristics, generation system, plant and equipment.

    2.4 The concept of combined cycle and co-generation electricity generation is

    explained in terms of fuel source and characteristics, generation system, plant

    and equipment.

    2.5 The concept of wind electricity generation is explained in terms of fuel source

    and characteristics, generation system, plant and equipment.

Please note

    Providers must be granted consent to assess against standards (accredited) by NZQA, before they can report credits from assessment against unit standards or deliver courses of study leading to that assessment.

    Industry Training Organisations must be granted consent to assess against standards by NZQA before they can register credits from assessment against unit standards. Electricity Supply Industry Training Organisation ; New Zealand Qualifications Authority 2012

    Providers and Industry Training Organisations, which have been granted consent and which are assessing against unit standards must engage with the moderation system that applies to those standards.

    Requirements for consent to assess and an outline of the moderation system that applies to this standard are outlined in the Consent and Moderation Requirements (CMR). The CMR also includes useful information about special requirements for organisations wishing to develop education and training programmes, such as minimum qualifications for tutors and assessors, and special resource requirements.
