What is UPFC in matlab?

Description. A Unified Power Flow Controller (UPFC) is used to control the power flow in a 500 kV transmission system. The UPFC located at the left end of the 75-km line L2, between the 500 kV buses B1 and B2, is used to control the active and reactive powers flowing through bus B2 while controlling voltage at bus B1.

What is Upfc power system?

A unified power flow controller (UPFC) is an electrical device for providing fast-acting reactive power compensation on high-voltage electricity transmission networks. It uses a pair of three-phase controllable bridges to produce current that is injected into a transmission line using a series transformer.

What is a unified power flow controller (UPFC)?

If you are not familiar with the UPFC, please see the reference page for the Unified Power Flow Controller (Phasor Type) block. The single-line diagram of the modeled power system is shown in 500 kV / 230 kV Transmission System . A UPFC is used to control the power flow in a 500 kV /230 kV transmission system.

What are the three parameters of UPFC?

In UPFC, the transmitted power can be controlled by changing three parameters of power transmission line namely transmission magnitude voltage, impedance and phase angle. The UPFC consists of two voltage source converters; series and shunt converter, which are connected to each other with a common dc link.

Is UPFC achieving stability?

The UPFC is a solid-state device, which can be used to control the active and reactive power. This thesis considers a typical three-machine nine-bus system as a case study for investigating the performance of UPFC is achieving stability.

How to plot the UPFC controllable region?

Run the simulation and look on the UPFC scope the P and Q signals who vary according to the changing phase of the injected voltage. At the end of the simulation, double-click on the blue block labeled “Double click to plot UPFC Controllable Region.”
