CHAPTER 2 LITERATURE REVIEW INTRODUCTION During the early part of the 20th century, small oscillations in synchronous generators became a problem for power system engineers. This phenomenon came to be known as ‘hunting’. It was particularly noticeable when a generator was synchronized to the system through a long line.

Thyristor-controlled reactors can be used for limiting voltage rises on lightly loaded transmission lines.

Contracting Co.) Main Power System parameters are System Voltages and Frequency which normally indicate the healthiness level (they indicate the level of Generated active and reactive Powers against the load power requirement).

In a healthy system, Voltage and frequency are close to the rated system values. A static VAR compensator (SVC) is a set of electrical devices for providing fast-acting reactive power on high-voltage electricity transmission networks. SVCs are part of the Flexible AC transmission system device family, regulating voltage, power factor, harmonics and stabilizing the system.

A thyristor-controlled reactor (TCR) is connected in series with a bidirectional thyristor valve. The TCR reactor generates inductive reactive power of SVC. TCR's are essentially shunt reactors, but the current is continuously regulated by the thyristor valves. such as Thyristor Controlled Series Reactors (TCSRs) and Thyristor Controlled Series Capacitors (TCSCs), are being used by several utilities to compensate their systems [8].

The primary function of a synchronous generator excitation system is to regulate the voltage at the generator output. In a synchronous machine, the rotating magnetic field necessary to induce voltage in the stator windings is produced by the dc current that circulates in the rotor or field winding.

•Shunt compensation is use to improve power factor. •In Shunt compensation FACTS are connected in parallel with power system and works like a controllable current source. •There are two types of shunt compensation. •If the inductive load is connected the lagging load current flows to compensate this shunt capacitor is used.

Static Var Compensator (SVC) is a power quality device, which employs power electronics to control the reactive power flow of the system where it is connected. As a result, it is able to provide fast-acting reactive power compensation on electrical systems. In other words, static var compensators have their output adjusted to exchange inductive or capacitive current in order to control a power.

synchronous compensator, thyristor controlled series capacitor along with fixed capacitor thyristor controlled reactor are also capable of improving the steady state condition i.e.

the transient condition. Thus the other solution for the increasing power transmission without any loss in the form of power quality can be FACTS technology [23].
