1. 1. Power Electronic Enhanced Distribution Transformer : Seamless Voltage Regulation with Extended Functionalities

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Nils Johansson; [2022]
   Keywords : Hybrid distribution transformer; Power converters; Voltage control; Hybrid power system; Reactive power; Hybrid distrubitionstransformator; Effektomvandlare; Spänningskontroll; Hybrida elnät; Reaktiv effekt;

   Abstract : On-load tap changers and static synchronous compensators (STATCOM) are the main components for voltage regulation and power quality optimization in the power system. STATCOMs are used in both industrial applications and utility to stabilize the grid and reduce downtime. READ MORE
