Thesis (MTech (Electrical Engineering))--Cape Peninsula University of Technology, 2009 / The purpose of this project is to develop methods for distribution network power quality'
variations monitoring. Power quality (PO) has become a significant issue for both power
suppliers and customers. There have been important changes in power system regarding to
power quality requirements. "Power quality" is the combination at voltage quality and current
quality. The main research problem of the project is to investigate the power quality of a
distribution network by selection of proper measurement, applying and developing the
existing classic and modern signal conditioning methods for power disturbance's parameters
extracting and monitoring. The research objectives are:
To study the standard lEC 61000-4-30 requirements. to investigate the common
couplings in the distribution network.
To identity the points for measurement, to develop MySQL database for the data from
the measurement and to develop MATLAB software tor simulation of the network
To develop methods based on Fourier transforms for estimation of the parameters of
the disturbances.
To develop software for the methods implementation,
The influence of different loads on power quality disturbances are considered in the
distribution network. Points on the network and meters according to the lEC power quality
standards are investigated and applied for the CPUT Bellville campus distribution network.
The implementation of the power quality monitoring for the CPUT Bellville campus helps the
quality of power supply to be improved and the used power to be reduced.
MATLAB programs to communicate with the database and calculate the disturbances and
power quality parameters are developed.
