This abstract illustrates distance protection scheme for high voltage power transmission line by using Principal Component Analysis (PCA) and Ensemble Decision Tree (EDT) methods. Discrimination between internal, external fault and power swing condition is a very interesting task in transmission line distance protection scheme due to large power system parameter variations and their complex structure.Therefore, instead of impedance or amplitude of current or voltage based approach this work used directional comparison based modified permissive overreach transfer trip (POTT) based approach that uses waveform of local end three phase voltages and currents and remote ends tripping signal which uses minimal bandwidth communication channel, and then PCA is used to reduce the dimensions of these voltages and currents samples that is utilized to train and test different EDTs for detection of internal, external faults and power swings, and it also provide EDT based backup protection in case of a communication failure that uses only local ends voltages and currents for protection. The power transmission line is modelled in PSCAD/EMTDC software to obtain the relaying under different operating conditions. The proposed algorithm will be evaluated in MATLAB under different operating conditions during Power Transfer and the tested data will be simulated in PSCAD/EMTDC by varying inception angle, fault location, fault resistances, power angle and fault types.
