VOLTAGE SECURITY IN FEEDERS BY UPFC

Abstract

Economic, increasing demand and
operational factors have forced the functioning of power
system close to operating conditions. In this Online
Voltage Security Assessment, it requires analysing the
severity of voltage margins and accordingly acting to
make the voltage level in the secured level utilising
proper FACTS devices. Due to the complexity of the
voltage behaviours, it still remains as an area where new
improvements become essential. FACTS devices play
vital role to secure voltage under all possible
contingencies. Both real and reactive powers can either
be absorbed or injected from or into the system with the
help of UPFC modules
