About the Influence on the Difference and the Islanding Test of the Resonance Load and the Motor Load

Abstract

The Islanding detection device of the most important protection instrument for the Utility—Interconnected Photovoltaic inverters the islanding phenomenon by the influence of the resurrection energy of the motor load and the resonance load. In the main discourse, it experimented on the individual operation by both measurements, and compared the amounts of electric energy of the motor load and the resonance load using PCS of a real machine and the effectiveness of the motor load was confirmed.
