Power quality improvement and reactive power compensationusing enhancedsliding mode controllerbased shunt active power filter and static VAR compensator

Abstract

The power quality is the challenging criteria in all equipment's at all levels comprise industrial sectors and consumer places. Some parameters are very sensitive which may affect and disturb the power quality. These parameters are harmonic current, power compensation and voltage sag. Providing the source without these parameters with efficient power quality is essential. Hence by selecting proper device the power output may reach without any interruption along with linear, non-linear and unbalanced loads. This paper introduces a Sliding Mode Controller (SMC), a very effective controller implemented with Shunt active filter and Static VAR Compensator (SVC) FACTS device which increases the reactive power compensation and suppresses the harmonic to enhance the system performance with high reliability.

Hybrid control strategies of SVC for reactive power compensation

“…One of the benefits of SVC formed by thyristor switching structures is that an infinite number of processes can be performed. Besides, the high accuracy of switching time also attained [9,10]. Thyristor is used as a valve for the connection of reactors, capacitors and additional devices connected to the electrical power system, which realizes the speed of the devices, without an electric arc, there is no impact switching effect and finally has an excellent performance [11].…”
