摘要：Islanding detection is of great importance for normal operation of distributed generation system. In this paper, Active Frequency Drift (AFD) method is chosen to illustrate its operation principle and concrete performance procedure in detail. On this basis, an improved method based on adaptive chopper factor is proposed to reduce the impact of the load property on AFD. The improved method can automatically change chopper factor according to different load properties to eliminate non-detected zone (NDZ)and accelerate islanding detection. Detailed analysis is included in this paper, finally simulations are carried out in Matlab to verify the proposed method. © 2017 IEEE.
