Abstract: Power Distribution system parameters, especially the conductance and susceptance, are important in the network analysis and performance studies. Power System applications such as State Estimation, Network Protection and Control, etc. depend critically on accurate network models based on precise line parameters. Many methods have been in the literature for transmission line parameters estimation, mostly considering the transposed line. Power distribution system consists mostly of un-transposed lines, where the distribution network parameter estimation, utilizes the phasor domain equations, and requires huge set of measurements.

In this seminar, we would like to propose a method based on the time domain equations with less set of measurements, which has an advantage over other methods. The literature focusses more on the estimating the conductance (G) and susceptance (B) matrices than on the passivity of the network. The distribution system line model always consumes active power for any applied voltage and at all frequencies as a result the passivity of the line is enforced with proper constraints. Different methods of estimating un-transposed overhead line and underground cable parameters with different set of constraints are presented. Time series data is employed for the purpose of estimating the various line parameters.
