چکیده

This paper presents a new islanding detection method based on the difference of the power transfer angle between the distributed generation and local load. After islanding, current id and iq will be changed by adding the variation to d_q transformation block of current. This makes voltage and frequency disturbance and therefore islanding is recognized. Active islanding detection method usually has a negative effect on power quality .The great advantage of this method include small negative impact on power quality. Performance of the proposed method will be evaluated and simulation results will be presented.
