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 ...

Power differential protection as primary protection of transmission lines and busbars
IET 9th International Conference on Developments in Power Systems Protection (DPSP 2008), 2008Active power differential protection has recently been proposed as a novel technique to increase the protection reliability of transmission lines and busbars. In comparison with current differential protection, it is more reliable, faster, needs less input parameters and communication devices; those make it suitable to be used as a protection scheme of

Transient based protection for power transmission systems
2000 IEEE Power Engineering Society Winter Meeting. Conference Proceedings (Cat. No.00CH37077), 2002This paper introduces new developments in fault transient based power system protection techniques. A brief review of history of relay development, which outlines the background of the new developments is first given in the paper. The concept of 'transient based protection' is then presented and the advantages of which over conventional techniques are ...

Control and protection of superconducting power transmission lines
IEEE Transactions on Magnetics, 1979The paper deals with the analysis of transient processes in a superconducting cable under current overloads and the possibility of stabilizing the superconducting state of the line by means of an automatic control system. The urgency of employing an automatic control system for the recovery and retaining of superconductivity in after-fault conditions ...

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.
