Abstract

A series compensation device employable in a Low Voltage distribution grid is presented in the paper. This compensator is connected in series with sensitive loads in a distribution system and is able to inject into the grid a controllable voltage to improve Power Quality. The series compensator is employable for compensating voltage dips, flicker and voltage variations. The compensation device can be also used for limiting the short circuit currents, in case of faults located downstream the compensator. The performances of the proposed series compensator and the associate control scheme are demonstrated through digital batch simulations and Control Hardware In the Loop (CHIL) real time simulations.
