要約(日本語): Active islanding detection methods are more effective and robust than the passive ones, but most active schemes have the disadvantages of complex structure, and power quality degradation to a certain extent. This paper proposes a correlation factor based islanding detection method (IDM) using current magnitude disturbance for ac grid interface systems like PV power systems. As an islanding detection index, the correlation factor between current magnitude disturbance and the corresponding inverter output voltage is used. The proposed method has fast islanding detection capability, whereas keeping high power quality. For the verification of the proposed method, the simulated results and experimental results of 3kW PV inverter are provided by IEEE Std. 929-2000 and IEEE Std. 1547.1-2005. The proposed correlation technique can be easily applied into other active anti-islanding methods based on the correlation between current and voltage after islanding occurs.
