Half-Wave Length Line Energization Case Test ?? Proposition of a Real Test

摘要

In Brazil big blocks of energy will be transported through distances between 2500 and 3000 km to the strong network nodes. Among the AC transmission systems alternatives being analyzed the half-wave length transmission seems to be the natural solution as the lengths involved are around a half-wave length of a 60 Hz frequency system, as the Brazilian one. As there is no half-wave transmission system in operation in the world, there is a major sense of caution in order to be the first to construct and use this new AC-link. In order to give some support a field test with a set of existing similar 500 kV lines that could be connected in series was proposed to simulate the AC-link behavior under some controlled switching. The proposed AC-link test was simulated in PSCAD/EMTDC.
