Abstract

In this paper, the economics of some alternative solutions for point-to-point transmission of bulk power over long distances, namely, HVDC and half-wavelength lines (HWLL), are evaluated. Also, the main technical aspects of the half-wave length transmission technology in order to define the line design and its required equipment are discussed. A two-line, 2500 km transmission system (which is half the wavelength of a 60 Hz power frequency) carrying 6000 MW is used as the base case to perform the comparison. Finally, issues related to the sensitivity of such a cost comparison between the HVDC and HWLL alternative is presented.
