FLEXIBLE ALTERNATING CURRENT TRANSMISSION

SYSTEMS(FACTS) A flexible alternating current transmission system (FACTS) is a system composed of static equipment used for the AC transmission of electrical energy.

They increase the reliability of AC grids and reduce power delivery costs.

They improve transmission quality and efficiency of power transmission by supplying inductive or reactive power to the grid.

Series compensation

FACTS is connected in series with the power system. It works as a controllable voltage source. On long lines, when a large current flows, this causes

a large voltage drop. To compensate, series capacitors are connected,

decreasing the effect of the inductance..

Shunt compensation

In shunt compensation, power system is connected in shunt (parallel) with the FACTS.

. It works as a controllable current source Shunt compensation is of two types:

1.Shunt capacitive compensation

2. Shunt inductive compensation

Shunt capacitive compensation

This method is used to improve the power factor. Whenever an inductive load is connected to the

transmission line, power factor lags because of lagging load current.

To compensate, a shunt capacitor is connected which draws current leading the source voltage.

The net result is improvement in power factor.

Shunt inductive compensation

This method is used either when charging the transmission line, or, when there is very low load at the receiving end

Shunt capacitance in the transmission line causes voltage amplification .

To compensate, shunt inductors are connected across the transmission line.

The power transfer capability is thereby increased .

Static Synchronous Compensator (STATCOM)

It is a static synchronous generator as shunt static var compensator whose capacitive or inductive current can be controlled independent of the system voltage.

APPLICATION

• This research will investigate the use of renewable dispersed energy system (wind-small hydro, hybrid scheme) and resulting grid interface problems and need for effective mitigative FACTS-based solution.

• Both stand-alone and grid connect wind energy conversion is not found yet

FACTS FOR THE FUTURE

FACTS technology can increase the loading on existing systems and assist in directing power flow in an interconnected network.

The first element in this work is to develop large semiconductors capable of handling power-class voltages and currents.

The increasing demand for electricity owing to the growing population and economic development worldwide is the most important factor in the growth of the global FACTS market.

CONCLUSION

FACTS technology provides an alternative to building new power transmission lines or power generation facilities.

It is a comparatively inexpensive and fast way to provide more power and control in existing networks, with minimal environmental impact.

FACTS solutions help power companies increase transmission capacity over existing AC power lines, providing fast voltage regulation, active power control and load flow control in meshed power systems.
