What is the equivalent length of R=2.5 ohm C=26 uF and L=0.5965 H ?
Hello,
The DC line is modelled using an equivalent-T network with the parameters R=2.5 ohm C=26 uF and L=0.5965 H. What is the equivalent length for these parameters? or How to calculate the line length with these parameters?
I think you are referring to the Cigre Benchmark Model of HVDC system. The reactance value is that of a smoothing reactor installed on the cable terminals and not the reactance of line. Considering that, the line length of 5 ohm resistance (2.5+2.5 ohm in series) can be calculated using R=pho*L/A. Where, A is the area of cross section of the conductor. pho is the resistivity of conductor (for copper it is 1.72E-8 ohm.m).
