Level: 
7
Credits: 
15 (0.125 EFTS)
Compulsory: 
No
Aim: 
To enable students to gain an understanding of three-phase power generation and transmission systems with an emphasis on generation, transmission and distribution systems.
Pre-requisites / Co-requisites: 
Students must be admitted to the Bachelor of Engineering Technology programme to enrol in this course. Pre-requisite: ENGGMG5016. Restriction: ENGGMG7010.
Topics include: 

New Zealand?s power system - control and operation, power stations, main power transmission lines, major substations, the DC inter-island power link, voltage and frequency control, reliability of supply, and purity of waveforms.
? Principle of operation, and overview of the characteristics of cylindrical and salient pole synchronous machines. Operation of generators stand-alone, in parallel, and on an infinite busbar.
? Generation synchronisation.
Construction, principle of operation and maintenance of overhead lines, towers, conductors, insulator, distribution links, line inductance, capacitance, and resistance.. Voltage, current, and power flows in short, medium and long lines.
Operation and use of surge arrestors.
Construction and operation of power cables, insulation, conductor material, formation of conductors, current capacity, capacitance, inductance, losses, and installation.
? Causes of faults and their effects, limiting fault currents, fault magnitudes for both symmetrical and unsymmetrical faults.
Development of a basic SLD design and perform basic fault levels (eg up to 4 generators, 4 transformers and 2 feeders).
Current making and breaking capacities of switchgear & HV fuses.
Operation and use of autoreclosers and sectionalisers.
? Neutral-earthing methods, insulated neutral, resistance earthed neutral, solidly earthed neutral. (MV and HV) eg direct, isolated, NER, GFN.
