Abstract
Non-detection zones (NDZs) are important index to evaluate the performance of islanding detection methods. A proper NDZs mapping can reflect application area of islanding detection effectively. In this paper, QwxCnorm space mapping is adopted in NDZs detection of active frequency drift with positive feedback (AFDPF). Relationship between NDZs size of AFDPF and feedback gain is deduced, and coefficient of initial disturbance is amended. NDZs are compared by simulation before and after coefficients are amended. Simulation results reveal that NDZs after coefficient amended are located in high factor of quality area and the harmonic distortion is reduced. If factor of quality is less than 2. S, there are no NDZs for AFDPF of islanding detection.关键词
