This paper presents accurate fault location method for series-compensated transmission lines. The algorithm utilizes limited measurements at one-end from the bus, where the fault locator (FL) is installed with additional information on amplitude of load current from the remote section. Two subroutines designated for locating fault distance - one for fault behind the series capacitors and another one for fault in front of the series capacitors. Then a special procedure to select the correct solution is utilized. This algorithm requires estimation of three-phase voltage drops across capacitors bank. For this purpose a nonlinear differential equation is solved on-line using a novel, numerically efficient algorithm. The other interest of this algorithm is independent of fault resistance and does not require any knowledge of source impedance. The proposed approach was tested via digital simulation using MATLAB. Applied test results corroborate the superior performance of the proposed approach. [ABSTRACT FROM AUTHOR] |
