Load power losses in a medium-voltage network lines

The paper presents a few algorithms calculating the load power losses, arising in the MV network lines in conditions of the inaccurate data about the MV/LV transformers loads. It describes being applied by the algorithms, simple ways of assigning to the transformers their loads resulting from the measurement data. It also contains the active power loss error analysis which allows to estimate the proposed solutions implemented in the program EkoStrop (Load power losses in a medium-voltage network lines).
