Use of indicators to optimise design of overhead transmission lines

The design of overhead lines (new lines, uprating or refurbishment) in the deregulated environment is critical to the competiveness and profitability of the utility company. Should, for example, the design limit the power transfer to levels, which prohibit sales of MW at peak periods, the losses can be enormous. This fact, as well as the limitations imposed on capital expenditure, make the optimisation of line design a critical activity.
