Несимметрия параметров электрических сетей 750 кВ ОЭС Украины в неполнореакторных режимах

Abstract

The paper presents a phase coordinate equation based mathematical model of an electrical network that allows reproducing single-ended modes under single or multiple asymmetry in the network. Studies of the complex unbalance in 750 kV electric networks in the Ukrainian united power grid are made, the unbalance resulted from open-phase switching of shunt reactors groups.
