Kuhlelo lwesimanje lwegridi yamandla, ukuhlanganiswa kwemithwalo ehlukahlukene engaqondile emikhulu edla amandla njengeziko likagesi i-arc, izigayo eziginqikayo ezinamandla amakhulu, ama-hoist, izitimela zikagesi, namapulazi omoya kulethe uchungechunge lwemiphumela emibi kugridi yamandla. .igridi.Le miphumela emibi ihlanganisa ukushintshashintsha kwamandla kagesi, ukulahlekelwa amandla kanye nama-harmonics, okungaholela ekungazinzini kwesistimu nokungasebenzi kahle.Ukuze kuxazululwe lezi zinkinga, izisetshenziswa zokuhlunga zesinxephezelo samandla aguqukayo we-high-voltage aguqukayo sezibaluleke kakhulu ekugcineni ukuqina nokuthembeka kwegridi yamandla.
Iidivayisi yokuhlunga isinxephezelo samandla ashukumisayo aphezulu we-voltage ephezuluiklanyelwe ngokukhethekile ukunciphisa imiphumela emibi ebangelwa imithwalo engaqondile futhi ephezulu yokusebenzisa amandla.Lawa madivayisi asebenzisa ubuchwepheshe bamandla kagesi athuthukisiwe ukuze anikeze isinxephezelo samandla asebenzayo asheshayo nanembile, ukucindezela kwe-harmonic kanye nokulawulwa kwamandla kagesi.Ngokwenza kanjalo, ikhwalithi yamandla nokusebenza kahle kwegridi kuyathuthukiswa, kuqinisekiswe ukutholakala kukagesi okungaphazamiseki futhi okuthembekile ezikhungweni ezehlukene zezimboni nezentengiso.
Amafasitela kagesi arc, izigayo eziginqikayo ezinamandla amakhulu, ama-hoists, izitimela zikagesi namapulazi omoya kubalulekile ekusebenzeni kwezimboni zesimanje, kodwa ukuhlanganiswa kwazo kugridi kungadala izinselele ezinkulu.I-nonlinearity kanye ne-intermittenncy yale mithwalo ingaholela ekungazinzini kwamandla kagesi, ukushintshashintsha kwamandla kanye nokuhlanekezela kwe-harmonic, konke okungathinta kabi igridi kanye nemishini kagesi exhunyiwe.Idivayisi yokuhlunga isinxephezelo samandla aguqukayo we-high-voltage ashukumisayo izidambisa ngempumelelo lezi zinkinga futhi iqinisekisa ukuzinza okuphelele nokuthembeka kwegridi yamandla.
Ukwengeza, ukuhlanganiswa kwemithombo yamandla avuselelekayo njengamapulazi omoya kwengeza ebunzimeni begridi.Izikhawu zokuphehlwa kwamandla omoya kungaholela ekushintshashintsheni kwamandla kagesi kanye nokungalingani kwamandla, okudinga isinxephezelo samandla asebenzayo anamandla kanye nezixazululo zokulawulwa kwamandla kagesi.Idivayisi yesihlungi sesinxephezelo samandla aguqukayo anamandla aphezulu ingalawula futhi izinze amandla kagesi wegridi, iqinisekise ukuhlanganiswa kwegridi okungenazihibe yamandla avuselelekayo, futhi inciphise umthelela kukho konke ukuzinza kwegridi.
Kafushane, izisetshenziswa zokuhlunga zesinxephezelo samandla asebenzayo we-high-voltage ashukumisayo zidlala indima ebalulekile ekugcineni ukuzinza nokuthembeka kwamagridi amandla esimanje.Ngokuhlinzeka ngesinxephezelo samandla asebenzayo esisheshayo nesinembile, ukucindezela kwe-harmonic kanye nokulawulwa kwamandla kagesi, lezi zixhobo zinganciphisa ngempumelelo imiphumela emibi yemithwalo engeyona yomugqa kanye namandla amakhulu kanye nemithombo yamandla avuselelekayo ngezikhathi ezithile.Ngokukhula okuqhubekayo kwesidingo samandla, ukubaluleka kwamadivayisi okuhlunga isinxephezelo samandla aguqukayo aphezulu ane-voltage ephezulu ukuze kuqinisekiswe ukuzinza nokusebenza kahle kwegridi yamandla kuyabonakala.
