Abstract :
The load data is incomplete in most distribution networks especially in the developing areas. It is necessary to process load data before distribution networks analysis. In this paper the methods of load data processing are studied and two parts of work are done. For missing data at measurement points, a combined model based on the least square theory is proposed to compensate the blank data. And for load data at non-measurement points, loop impedance method is adopted to calculate the unknown branch current so as to indicate unknown load data. Two examples are given to show the validity of the methods
