k-NN based fault detection andclassification methods for powertransmission systems
for fault detection and classification in distance protection. In these methods
by finding the distance between each sample and its fifth nearest neighbor in a predefault window
the fault occurrence time and the faulty phases are determined. The maximum value of the distances in case of detection and classification procedures is compared with pre-defined threshold values. The main advantages of these methods are: simplicity
low calculation burden
acceptable accuracy
and speed. The performance of the proposed scheme is tested on a typical system in MATLAB Simulink. Various possible fault types in different fault resistances
fault inception angles
fault locations
short circuit levels
X/R ratios
source load angles are simulated. In addition
the performance of similar six well-known classification techniques is compared with the proposed classification method using plenty of simulation data.
Abstract
This paper deals with two new methods
based on k-NN algorithm
for fault detection and classification in distance protection. In these methods
by finding the distance between each sample and its fifth nearest neighbor in a predefault window
the fault occurrence time and the faulty phases are determined. The maximum value of the distances in case of detection and classification procedures is compared with pre-defined threshold values. The main advantages of these methods are: simplicity
low calculation burden
acceptable accuracy
and speed. The performance of the proposed scheme is tested on a typical system in MATLAB Simulink. Various possible fault types in different fault resistances
fault inception angles
fault locations
short circuit levels
X/R ratios
source load angles are simulated. In addition
the performance of similar six well-known classification techniques is compared with the proposed classification method using plenty of simulation data.
