Abstract –
Flexible AC Transmission Systems (FACTS) use power electronic components to enhance controllability and capability of electrical power system. FACTS devices are able of opportunely modify voltage, phase angle and/or impedance and then the power flows at particular points in power systems . One of the more intriguing and potentia ....etc

Here, a hybrid flow controller (HFC) is introduced as a part of the of flexible ac transmission system (FACTS) controllers for steady-state and power-flow control of power transmission lines. The HFC is a hybrid compensator that provides series and/or shunt compensation. The major mechanical components of the HFC are:
-a mechanically switched phase-shifting transformer
- a mechanically switched shunt capacitor
-multimodule, series-connected, thyristor-switched capacitors and inductors

Usefulness of DC Power Flow for Active Power Flow Analysis



I. INTRODUCTION
STATIC power system analysis has always been
performed using full power flow. It is one of the
fundamental tools for power system analysis and is used in
the operational as well as planning stages. Vertically
integrated companies have used it to control their systems, as
well as to plan the optimal economic operation of generation
resources, either by means of optimal power flo ....etc

Unified Power Flow Controller

INTRODUCTION

Two main objectives of FACTS

Increase the TX capability of AC line
Control of power flow over the TX routes

UPFCs - most effective FACTS device

UPFC “ a device which control TX line impedance, voltage and phase angle



BASIC CONSTRUCTION OF A UPFC

Consists of two switching GTO converters
Shunt-connected
Series-connected

Both converters can operate in a rectifier mode or in an inverter mode

A DC branch links these two converters ....etc
