A research report submitted to the faculty of Engineering and the Built Environment,
of the University of the Witwatersrand, Johannesburg, in partial fulfilment of the
requirements for the degree of Master of Science in Engineering
Johannesburg 2014 / Clearances are an important aspect of High Voltage (HV) transmission line design,
construction and maintenance. A software tool that combines clearance violation
analysis and optimum loading operating conditions for power lines could save power
utilities the capital cost of refurbishing transmission power lines that marginally
exceed maximum power line clearance distances. This can be achieved by operating
the power lines at an optimum amperage level for any given set of weather
conditions.
This research project proposes a low cost MATLAB® based software tool that detects
clearance violations and determines operational limits on transmission power lines
using prevalent weather conditions as well as the power line amperage. Various
power lines around the states of Missouri and Illinois in the United States of America
are analysed to test the viability and functionality of the software. In order to validate
the accuracy of the program, the results obtained were compared to results from PLSCADD
®.
