Level 6
Credits 15


Describe the New Zealand Power System and explain key aspects e.g. system control, basic terminology (GXP, GIP, infinite bus, frequency and load control, spinning reserve, control periods, ripple and load control methods)

Describe the types of generation systems in use in NZ (large scale >1000kW - hydro, geothermal, thermal, co-generation). (I.e. an overview)

Describe the transmission system (aerial, towers, HVDC)

Describe the distribution system (up to 66kV, cables and aerial, district and zone substations)

Describe the application of power transformers in a MV and HV environment

Describe the process of generator synchronisation

Earthing systems for MV and HV networks (direct, isolated, NER, GFN)

Describe and apply the process of current interruption and selection of appropriate switchgear

Describe and apply basic SLD design and perform basic fault levels (e.g. up to 4 generators, 4 transformers and 2 feeders)
