Abstract
Transmission lines are an integral part of a transmission network in power system, and estimation of their parameters is necessary for various power system planning studies. This thesis presents a new formulation for parameter estimation of two-terminal and three-terminal transmission lines using least-square approach. This formulation is compared with another traditional method for two-terminal line parameter estimation of transmission lines and the results are tested on field data. Based on the results from field data, it is demonstrated that the least-square method is significantly better than the traditional method, as it results in smaller variance and better accuracy of the estimated parameters of a two-terminal transmission line. Additionally, a mean-filter based method is proposed for two-terminal transmission line and is shown to be much better than the traditional method, based on field results. Finally, the least-square based formulation is extended to parameter estimation of a three-terminal transmission line and validity of algorithm is verified through results of field data.
