Abstract :
Generalized admittance matrix models of line and transformer segments are presented. These models are used to formulate the real and reactive branch power flow and bus power injection measurement equations for a radial system state estimator. The formulation does not require conversion of element parameters to per unit and properly accounts for transformer phase shifts. Finally, the estimator´s performance is assessed using several measurement configurations
