Enhancement of Power Quality Approach Using Unified Power Quality Conditioner

The connection of a three-unified power quality conditioner is an effective and economical control approach for compensating for harmonics and Load-Q energy usage (UPQC). This paper proposes a control approach for a unified power quality conditioner as a dual control in the distribution system to reduce power quality issues. End-user-polluted loads are always at the heart of power quality problems. UPQC systems are employed in this study to regulate operations and series power conditioning. The filters convert non-sinusoidal electrical quantities into sinusoidal electrical values by injecting current and voltage at a large phase angle. This is referred to as dual compensation. The proposed UPQC system is compatible with both 3P3W and 3P4W distribution systems.
