Abstract


  • etermining sources of voltage unbalance (VU) and

    quantifying their individual contributions in an interconnected

    network is a complex task due to multiple interactions that take

    place between them. Post-connection VU emission assessment

    techniques in relation to customer installations are important

    not only in compliance assessment according to IEC/TR 61000-3-

    13:2008 Limits - Assessment of emission limits for the connection

    of unbalanced installations to MV, HV and EHV power systems,

    but also in determining the various emission contributors in

    the power system being considered. This paper presents a case

    study on the application of a recently developed post-connection

    VU emission assessment methodology to a 66 kV interconnected

    sub-transmission network owned and operated by an Australian

    network service provider. The study incorporates the evaluation

    of constituent components of the resultant VU factors at bus bar

    levels, identification of the dominant emission contributors and a

    methodology for ranking of the emission contributions made by

    the asymmetrical transmission lines in the network. Outcomes

    obtained through the VU emission assessment methodology are

    validated using three-phase, unbalanced load flow analysis.
