Circuit Description
A UPFC is used to
control the power flow in a 500 kV /230 kV transmission system. The system,
connected in a loop configuration, consists essentially of five buses (B1 to
B5) interconnected through transmission lines (L1, L2, L3) and two 500 kV/230
kV transformer banks Tr1 and Tr2. Two power plants located on the 230-kV system
generate a total of 1500 MW which is transmitted to a 500-kV 15000-MVA
equivalent...
