With　the　increasing　number　of　sensitive　devices　in　modern　industry,　the　problem　of　voltage　sag　has　become　a　very　serious　power　quality　problem,　which　has　caused　very　serious　impacts　and　huge　economic　losses　to　users.　At　present,　few　scholars　at　home　and　abroad　have　studied　the　influence　of　voltage　sag　on　gas　compressor　stations　and　treatment　measures.　For　this　reason,　this　paper　will　study　the　influence　of　voltage　sag　on　gas　compressor　stations　and　put　forward　voltage　sag　treatment　measures　for　gas　compressor　stations.　Firstly,　analyze　the　voltage　sag　sensitive　equipment　and　process　links　in　the　compressor　station,　and　get　the　mechanism　of　how　the　voltage　sag　affects　the　normal　operation　of　the　compressor　station　and　the　impact　caused　by　it;　secondly,　propose　the　electrical　and　physical　treatment　plan　for　the　compressor　station;　finally,　taking　a　large-scale　compressor　station　as　an　example,　the　treatment　plan　is　designed,　and　the　technical　and　economic　comparison　proves　that　the　plan　in　this　paper　has　higher　cost　performance　and　feasibility.　©　2022,　The　Author(s),　under　exclusive　license　to　Springer　Nature　Singapore　Pte　Ltd.
