UPFC Simulink Model
Hi I would like to know the details of the Unified Power Flow Controller for the transmission system as well as for the Simulation Study and Dynamic Analysis of Unified Power Flow Controller?

Re: UPFC Simulink Model
A Unified Power Flow Controller (UPFC) is used to manage the power flow in a 500 kV transmission system. The UPFC located at the left end of the 75-km line L2, connecting the 500 kV buses B1 and B2, is used to manage the active and reactive powers flowing through bus B2 while controlling voltage at bus B1. It comprises of two 100-MVA, three-level, 48-pulse GTO-based converters, one connected in shunt at bus B1 and one linked in series between buses B1 and B2. The shunt and series converters can switch over power through a DC bus. The series converter can infuse a maximum of 10% of nominal line-to-ground voltage (28.87 kV) in series with line L2. This pair of converters can be operated in three modes: • Unified Power Flow Controller (UPFC) mode, when the shunt and series converters are interrelated through the DC bus. When the cut off switches between the DC buses of the shunt and series converter are opened, two additional modes are accessible: • Shunt converter functioning as a Static Synchronous Compensator (STATCOM) controlling voltage at bus B1 • Series converter functioning as a Static Synchronous Series Capacitor (SSSC) controlling injected voltage, while maintenance injected voltage in quadrature with current. The Simulation Study and Dynamic Analysis of Unified Power Flow Controller for Industrial and Educational Purposes details has been attached in the below file Model of the UPFC Controlling Power on a 500 kV/230 kV Power System (power_upfc) |
