Reactive Power Flow Control Using Static Var Compensator to Reduce Harmonic and to Improve Power Stability in Transmission System (original) (raw)

2021, International Journal of Advance Research and Innovative Ideas in Education

As one of the traditional solutions, the flexible systems of current transmission systems (FACTS) are designed to make power systems more efficient, improve stability and energy quality, and these systems are used in different parts of the world including our country. In general, FACTS can be defined as systems that provide voltage, impedance and phase angle to AC systems. With recent studies, the use of modern technology devices such as static VAr compensator and static synchronous compensator is becoming increasingly common to ensure energy quality in energy systems. In addition, due to advances in semiconductor technology, static VAr compensation systems have been introduced for use on the middle and upper power side. The most important feature of these systems is that they can compensate without requiring active power from the grid. In this study, the required operating power is required by a system provided using a fixed VAr compressor consisting of a thyristor-controlled responder and the properties of a thyristor switch capacitor. In simulation studies, active energy is provided by a static compensator instead of a power source. In this way, unnecessary use of power in the system was prevented. It is recommended that static VAr solutions be used especially when there is unbalanced load and fast operating power required.
