Abstract
The paper presents a comparative investigations of estimation of power system state in polar and rectangular coordinate systems. The estimation with the use of the weighted least squares method is considered. During investigations, impact of a coordinate system, stress of a power system and a data redundancy on such parameters of a state estimation as: number of iterations, the condition number of the gain matrix and parameters characterizing accuracy of calculation results and reliability of estimation is analyzed.
