VAR Management to Improve Maximum Loading In IEEE 30 Bus System Using FACTS Controllers

The maximum loading of the transmission lines depends upon various limits. These are related to the environmental conditions, length of the line and various stability related issues. The VAR plays important role in maximising the power transfer through a transmission line. The FACTS Controllers have a major part to play in the VAR Management, in order to increase the maximum loading capability. This gives an additional benefit of enhancing the voltage stability margin of the entire system as well. In this paper this aspect of VAR Management, is investigated for an IEEE 30 Bus Test System incorporating various FACTS Controllers like TCSC, STATCOM and SVC.
