ENGG DE6401 Power Systems 1

This course covers three-phase power systems with an emphasis on generation, distribution, and transmission systems.

Learning Outcomes:

  1. 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).                                                                                                                                                                     
  2. Describe the types of generation systems in use in New Zealand (large scale > 1000 kW – hydro, geothermal, thermal, co-generation). (i.e. an overview)                                                                                                                                                          
  3. Describe the transmission system (aerial, HVDC). 
  1. Describe the distribution system (up to 66 kV, cables and aerial, district and zone substations.                                                                                     

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

  1. Describe the process of generator synchronisation. 
  1. Earthing systems for MV and HV networks (direct, isolated, NER, GFN) 
  1. Describe and apply the process of current interruption and selection of appropriate switchgear. 
  1. Describe and apply basic SLD design and perform basic fault levels (e.g. up to 4 generators, 4 transformers, and 2 feeders).
