A Method to Determine Connection Phase of Transformer with an Optimizing Filter

Abstract

To know connection phase of transformer and use it for power flow simulation, we proposed a method to determine connection phase of transformer by using smart meter data and optimizing filter. A characteristic of proposed method is that the filter is improved by using previous result of determination and learning where frequency component is useful for it. We clarified that the proposed method is better than a conventional method filter is not optimized.
