Simulation on Calculation Accuracy of Three Methods for Live Line Measuring the Parameters of Transmission Lines with Mutual Inductance ()
ABSTRACT
Live line measurement methods can
reduce the loss of power outages and eliminate interference. There are three
live line measurement methods including integral method, differential method
and algebraic method. A simulation model of two coupled parallel transmission lines spanning on the same towers is built in PSCAD and the calculation errors of these three methods
are compared with different sampling frequencies by using of Matlab. The effect
of harmonic on calculation is also involved. The simulation results indicate
that harmonic has the least effect on the algebraic method which provides
stable result and small error.
