Innovative 10–110 kV Compact Controlled Overhead Lines

Abstract

This chapter describes how the implementation of compact overhead lines equipped with FACTS devices, including phase angle regulator settings (compact controlled OHL), appears to be one of the most effective ways of power grid development. Compact-design OHL equipped with FACTS have many improvements over previous devices. The devices provide a 1.2-1.6-fold increase in OHL capacity without raising their voltage class. A 1.5–2-fold reduction in the area of land allocated for OHL with equal capacity. An electromagnetic field reduction in the external space, decreasing environmental effects and the impact on people. A 15–30% decrease of total costs per power transfer unit. The total energy loss reduces the power system, increasing OHL mechanical strength under severe weather conditions. Results of the comprehensive research and development in relation to 10–110 kV compact controlled power transmission lines together with theoretical bases, substantiation, and methodological approaches to their practical application and design experience are given in the chapter.
