Optimized Conductor Positioning for Three-Phase Double-Circuit Transmission Line to Reduce Line Capacitance

Multistart techniques are very useful in solving global optimization problems. Different algorithms and tools have evolved from the multistart approach to find optimal solutions to non-linear programming (NLP) problems. A modified version of the global search (MGS) toolbox is proposed here. MGS is applied to optimally reduce the capacitance of the transmission line. The algorithm is tested with three-phase double-circuit transmission lines with different voltage ratings, like 66 k V, 110 k V, etc.
