Abstract: This paper conducts a study with the view of optimizing the reactive power flow on 400 kV and 765 kV Transmission Lines in the Cape Regions, South Africa. The power flowing on the system has a significant reactive component due to the long transmission distances. The appropriate flow of reactive power and the management of VAr sources are essential in the overall performance of this part of the system since it impacts directly on the available levels of supply capacity. The report will provide specific recommendations on optimal SVC voltage set-points and droop settings, tap-changer reference values and shunt device switching philosophy. As a starting point, the reactive power flow in the year 2006 was examined to establish a “base case” against which “future year” cases could be referenced. Two future dates were considered in the analysis: 2009 and 2012. Results show the reason why a VAr originates in a network and how to deal with these problems. The flow of steady-state reactive power on the system was analysed in 2009 and 2012.
