Abstract

The series compensator is a challenging solution for power quality problems related to the voltage. One of the most common control algorithms used for the series voltage compensator is the symmetrical component method. This paper introduces a new Recursive Least Square (RLS) structure for symmetrical components estimation. This structure is capable of dealing with Multi Output (MO) systems for parameter estimation and is called MO-RLS. A novel feed forward control based on the proposed MO-RLS is dictated for the series compensator not only to compensate for the zero and negative sequence components, but also to regulate the positive sequence component to the nominal load voltage. One advantage of the proposed control system is its insensitivity to parameters variation, a necessity for the series compensator. Simulations of the proposed algorithm are conducted to show the robustness, the high accuracy and the fast dynamic performance of the novel system.
