I am looking for existing litterature on the effect of fault inception angle during fault in three phase long distance lines.
Fault inception angle is the angle of the Voltage phasor of the line right before short circuit (with ground).
Thank you
Modern numerical distance protection tracking all the time all values for the purpose of correct operation. Therefore, the any angle is also track. In numerical distance protection system, there are several parameters for defining characteristic of quadrilateral distance zones. With those parameters, it can be influence on relay protection operations. Slope of distance protection characteristic can be fine-tune for various goals. For example, high loaded lines, phase to phase faults, phase to ground fault, power swing, pole slip, etc. For you can be useful to read manuals for relay protection from several vendors, GE, SEL, Toshiba, ABB, Siemens, etc.
Please refer to the IEEE Journal transaction below:
Wavelet-Based ANN Approach for Transmission Line Protection by Francisco Martín, Member, IEEE, and José A. Aguado, Member, IEEE
They studied the impact of changing the inception angle.
