Development of grid‐interconnection inverter with an islanding detection function by synchronized injection of harmonic active signal

Nunomura Naoto; Yoshida Yoshiaki; Suzuki Hirokazu

摘要

Abstract >We propose the islanding detection method using harmonic current as active signal. The active signal can be injected in the suppressed direction of the harmonic voltage during grid interconnection. On the other hand, the active signal is injected in the synchronized direction of the harmonic voltage due to the loads during islanding operation. As the result, the harmonic voltage is increased and the islanding operation is detected within 0.2 seconds. We have developed the single phase inverter for grid‐interconnection of low voltage with these functions and performed the experimental verification. </abstract> </span> <span class="z_kbtn
