Power system transmission section security protection control program
2010 International Conference on Machine Learning and Cybernetics, 2010The removal of overload lines can cause power flow transferring, which may give rise to some transmission lines overload. By analysis of available methods of determining transmission sections with shortcomings, this paper proposes a new way to determine transmissions section based on real-time power flows, and then deduce a new criterion of ...

Active power differential algorithm for protection of transmission lines
PowerTech Budapest 99. Abstract Records. (Cat. No.99EX376), 2003A differential algorithm for phase selective detection of high impedance single-phase-to-ground faults (HIF) on high voltage lines is presented. It is based on the recognition of the fundamental frequency active power consumption of a resistive fault.

Experimental evaluation of power differential relay for transmission line protection
2009 IEEE/PES Power Systems Conference and Exposition, 2009An experimental evaluation of a power differential relay is conducted and the results are described. The experimental setup consists of a generator connected to the network via a transmission line protected by the power deferential relay. The relay input signals, fundamental active and reactive powers, are locally computed from the complex product of ...

Performance analysis of power differential based transmission line protection
2017 International Conference on Energy, Communication, Data Analytics and Soft Computing (ICECDS), 2017This paper deals with investigation of novel fault detection for the protection of transmission line. Conceptually the difference of the average quantities for phase active power entering and leaving the lines are compared Computation of these quantities is carried out via simulating a tie line connecting two power system networks using MATLAB.

Some observations for distance protection of power transmission lines
IEEE Southeastcon 2009, 2009This paper presents some observations related to distance protection for power system transmission lines. Classical distance protection relays adopt the line terminal voltage and line current to calculate the distance between the fault and the relay location and then make a decision on whether a tripping signal should be issued and, if so, what the ...
