Title :
Voltage optimization
Abstract :
This paper deals with the voltage unbalance in three-phase circuits which introduces additional losses and reduces the stability of the 600 V distribution system. For automatic voltage regulation, there are methods of voltage-level optimization available that will compensate for voltage changes. These generally involve a tap-changing transformer in combination with an automatic voltage regulator. To mitigate voltage unbalance autotransformer with a delta winding and a buck boost transformer with dynamic voltage compensation can be used. To mitigate voltage harmonics active filters that cancel harmonic current distortion can be used
