Harmonic Transfer between Voltage Levels in AC Systems

Abstract

Harmonic transfer between different levels of ac systems increases the difficulty in harmonic identification and governance. From the view of harmonic transfer coefficients, the paper firstly establishes a harmonic infiltration equivalent model of different voltage levels, and then analyzes the formula of harmonic transfer coefficients. Finally, the computational and simulation analysis are carried out in MATLAB software to study the factors that affect the harmonic transfer coefficients between different voltage levels.
