Fault Location Method Based on Travelling Wave Theory; Case Study in a 20 kV Distribution Network
Mahdi Mozaffari Legha, Naeim Arab Sarbijan
In this paper proposes a new fault location method based on travelling wave theory and electric system behaviour in time domain. Furthermore, the development of a new protection device where it is implemented is presented. The performance of the proposed method has been evaluated in a 20 kV distribution network modelled in PSCAD/EMTDC. Results from simulations are presented, varying ground resistivity, fault resistance, fault type and the location of the fault; furthermore, harmonic distortion has been considered in the distribution network model.
