Digital Distance Relaying
author
Abstract:
Increasing interest is being shown in the use of microprocessor for protection, switching and data acquisition required in modern high voltage substations. One of the most difficult functions to fulfill is that of transmission line distance protection employing samples of the voltage and current waveform taken from high voltage transducer equipment at the usual relaying point. This paper examines and compares different digital algorithms suitable for distance measurement, with particular reference to their accuracy and speed of calculation.

Background: With the arrival of the industrial Century, the educational system changed and different forms of education, including distance Education were created. Firstly, distance education based on traditional learning theories, but because that these theories are not able to respond and solve the challenges facing the education system in the modern century connectivism theory was creat...
full textDecision tree based fault detection and classification in distance relaying
This paper presents a new approach for fault detection and classification in transmission line using Decision Tree (DT). The DT based fault detection algorithm uses 1/4th cycle data of fault currents from fault inception, to generate the optimal decision tree for fault detection. Similarly, the DT based classification algorithm takes half cycle data from fault inception of three phase currents ...
