Power Quality Conditioner

This paper presents the new control algorithm for three-phase, four-wire distributing system using unified power quality conditioner (UPQC). The UPQC, a combination of series and shunt active filter (AF) with common dc link, is one of the best solution towards the compensation of voltage sag, swell problems and also compensate voltage flicker/imbalance, reactive power, negative sequence current and maintain zero voltage regulation (ZVR) at the point of common coupling (PCC) on distribution system. The series AF is seen by using a three-phase, three leg voltage source inverter (VSI) and the shunt AF is of a three-phase, four leg voltage source inverter (VSI). The proposed model of the UPQC is developed in the MATLAB/SIMULINK environment and the simulation results prove the power quality improvement in the system.

Power Quality Conditioner

This thesis addresses the Unified Power Quality Conditioner (UPQC) which is a major custom power solutions capable for load balancing, power factor-correction, voltage regulation, voltage and current harmonics mitigation in a three-phase three-wire distribution system for different combinations of linear, non-linear and dynamic loads. The unit template technique (UTT) is used to get the reference signals for series active power filter and shunt active power filter which utilizes two closed loop PI controllers. The design of three- phase three-wire UPQC includes the design of shunt controller (SHUC) and series controller (SERC).

The essential focus of this endeavor is examination of three phase four wire UPQC available for use structures by neural framework. The bound together power-quality conditioner (UPQC) is used to calm the current and voltage-related power-quality (PQ) issues in the meantime in three-arrange four-wire course structures. Among most of the PQ issues, voltage hang is a significant issue in three-arrange four-wire scattering systems. In this paper, another procedure is proposed playing out the plan parallel electrical cable trim. As such, despite when only a three-organize three-wire control structure is available at a plant site, the UPQC can do control line pay for presented loads that require a fair-minded channel to work. Not exactly equivalent to the control philosophies used in most of UPQC applications in which the controlled sums are nonsinusoidal, this UPQC uses a twofold pay technique, with the ultimate objective that the controlled sums are continually sinusoidal. Neural System controller have been used to make the proposed methodology online for least real power implantation with UPQC by using the PSObased data for different voltage rundown conditions. In the proposed system PI controller substituted by NN controller for better precision.
