Au­to­mated smart grids

DEMM Engineering & Manufacturing - - CONTENTS -

To­day’s smart grids rely on equip­ment called pha­sor mea­sure­ment units (PMUs) to de­liver real-time, mis­sion crit­i­cal data on the volt­age, cur­rent, fre­quency, and phase within the dis­tri­bu­tion smart grid.

For the smart grid sys­tem to work re­li­ably, PMUs must be cal­i­brated so their data is con­sis­tent, ac­cu­rate and cred­i­ble, and so that mod­els from dif­fer­ent man­u­fac­tur­ers are in­ter­op­er­a­ble.

NIST, The Na­tional In­sti­tute of Stan­dards and Tech­nol­ogy, awarded Fluke a de­vel­op­ment grant in 2010 to get the project un­der­way.

The re­sult­ing Fluke Cal­i­bra­tion 6135A/ PMUCAL Pha­sor Mea­sure­ment Unit Cal­i­bra­tion Sys­tem is the only au­to­mated and trace­able PMU cal­i­bra­tion sys­tem avail­able to­day. It fills an es­sen­tial need for PMU de­sign­ers and man­u­fac­tur­ers, na­tional metrol­ogy in­sti­tutes, third party cal­i­bra­tion houses and elec­tri­cal util­i­ties.

The 6135A/PMUCAL is an in­te­grated sys­tem of six com­po­nents that com­pletes the ap­prox­i­mately 600 tests that cer­tify a PMU con­fig­u­ra­tion meets the lat­est per­for­mance stan­dards of the IEEE Stan­dard for Syn­chropha­sor Mea­sure­ments for Power Sys­tems (IEEE C37.118.1:2011 and IEEE C37.242).
