| Abstract: | Shutter island effect,unavoidable during grid connection of solar photovoltaic generation,has a high potential safety hazard. Therefore,in view of the characteristics of this distributed power,it is essential to adopt a method of the passive or active detection mode for quick and accurate detection,and to adopt anti-shutter island effect measures to guarantee the safety of the grid,facilities and workers.The self-adaptive logical frequency shifting can solve the blind spot problem during the detection. |
