Optimization of the operating conditions of an extra high-voltage power line with intermediate substations

摘要

Algorithms for optimizing the operating conditions of an extra high-voltage power line with intermediate substations in terms of voltage and reactive power are considered, in which corona effects and operational limitations are taken into account. It is pointed out that the operating conditions of a high-voltage power line are best modeled by using complete line equations in hyperbolic functions, by modeling corona losses taking the voltage distribution along the line into account, and using numerical methods. An optimum range of the voltage profile along a high-voltage power line with intermediate substations is determined more exactly.
