Develops a tool that accurately judges flicker occurrence in low-voltage distribution systems, indicating practical applications for better power quality.
In this paper, we proposed a method to judge the occurrence of approximately 6Hz flicker caused by the islanding detection function equipped in PCSs connected to low-voltage distribution systems. We compared the experimental results in a full-scale distribution facility with the judgment results and confirmed that the judgment accuracy was sufficient. Furthermore, we confirmed that a tool using this method can judge the occurrence of flickers on a distribution system scale within a period that is practical.
