Estimation of a shunted radial transfer path dynamics using PMUs

This paper proposes an algorithm to estimate the variables of a model of two machines connected by unknown shunted transfer path, using PMUs data. The variables include static quantities such as the line impedances and the location of the shunt, in addition to the transient impedances, electromagnetic forces, and the inertias of the machines. The innovation here is the development of a transformation to convert the transfer path with shunt compensation into a radial transfer path and further estimate the system parameters and variables. The advantage of the proposed algorithm is the minimal use of PMUs.
