Emhlabeni wanamuhla osheshe wavela ngokushesha, isidingo sezinhlelo ezisebenzayo zokusabalalisa amandla zibaluleke kakhulu kunangaphambili. Izinkinga zekhwalithi yamandla ezifana nokungalingani kwamandla, ama-harmonics, nokungalingani kwamanje kungaholela ekushintshashintsheni kwamandla, ukwehluleka kwemishini, nokunciphisa ukusebenza kahle kwamandla. Ukubhekana nalezi zinselelo, izixazululo zobuchwepheshe ezithuthukile ezifanaAma-generator athuthukile we-static var(Ama-SVG) aqhamuke. Kule bhulogi, sizohlola izici ezibalulekile nezinzuzo ze-SVG futhi sibone ukuthi singaguqula kanjani ukuphathwa kwekhwalithi yamandla.
Umgomo oyinhloko wanoma yiluphi uhlelo lwamandla ukufezekisa i-Uniform Power Factor (cos Ø = 1.00). I-SVG ibheka ukuhlinzeka isinxephezelo samandla asebenzayo ukuze kuqinisekiswe ukuthi isici samandla sihlala sihle. Ngokulawula kahle umphumela wamandla okuphendula, ama-SVG angahlelela ubudlelwano phakathi kwamandla kagesi nowamanje, akhuthaza ukusetshenziswa kwamandla okwenziwe amandla kanye nokunciphisa izindleko zokusebenzisa.
Ngaphezu kokunxephezelwa kwamandla okusebenzayo, i-SVG futhi ihlinzeka ngokunxephezelwa kwesinxephezelo se-harmonic. Ikunciphisa ngempumelelo imiphumela elimazayo yemiyalo ye-harmonic, ikakhulukazi i-3rd, 5th, 7th, 9th, 9th kanye ne-11. Ngokuqinisekisa ukuhamba kukagesi okubushelelezi, i-SVG ivikela imishini ebucayi, inciphisa ukulimala futhi inweba impilo yokufakwa kukagesi.
Ukuguquguquka kwe-SVG kuboniswa emandleni ayo okuhlinzeka isinxephezelo se-capacitive kanye ne-actictive ngaphezulu kwe--1 kuya ku- +1. Lesi sici sivumela onjiniyela besistimu yamandla ukuba bakhethe umthamo weyunithi ngokuya ngezidingo zabo ezithile. Ukuthi inhloso ukulungiswa kwe-Power Factor, ukulungiswa kwe-harmonic, noma bobabili, i-SVG ingenziwa ngokwezifiso ngokufanele ukwengeza ukusebenza okuphelele kanye nohlelo lokusabalalisa kwamandla.
Ukungalingani kwamanje ngezigaba ezahlukahlukene kungaholela ekusetshenzisweni kwamandla okungasebenzi kahle, ukunqwabelana ngokweqile kanye nama-voltage amaconsi. I-SVG ixazulula le nkinga ngesici sayo sokulungiswa kwamanje se-Imlisance. Ngokuhlaziya ngokunembile ukugeleza kwamanje nokwenza izinguquko ezidingekayo zesinxephezelo, i-SVG iqinisekisa ukusatshalaliswa kwamanje okulinganiselayo, ngaleyo ndlela ithuthukise ukwethenjwa kohlelo lwamandla nokuqina.
Ukuze uhlangabezane nezidingo zekhwalithi ehlukahlukene yamandla, i-SVG ihlinzeka ngesinxephezelo semali yokunxephezelwa kwamandla kagesi ka-90kvar. Lesi sikhundla esiphanayo siqinisekisa ukuthi ngisho nezinhlelo zamandla ezifuna usizo zingazuza ngamakhono ayo athuthukile. Ukusuka kumayunithi amancane wezimboni kuya ezinqeni ezinkulu zezentengiso, i-SVG ihlinzeka ngesenzo esidingekayo ukuze kugcinwe amazinga aphezulu wekhwalithi yamandla.
Njengoba ukufunwa kwamandla kuqhubeka ukukhuphuka, isidingo sezixazululo zekhwalithi yamandla athuthukile. Ama-turt advanced advan vargerotors (SVGS) adlula okulindelwe ngokunikeza isinxephezelo samandla asebenzayo esisebenzayo, ukucindezelwa kwe-harmonic, inxephezelo esenziwe ngezifiso kanye nesinxephezelo esibonakalayo, nokulungiswa kwamanje, kanye nekhono elibalulekile elilinganiselwe. Ngokusebenzisa i-SVG, amasistimu kagesi angathuthukisa ukuqina, ukuthembeka, kanye nokusebenza kwamandla. Usebenzisa ubuchwepheshe bezinguquko ze-SVG buqinisekisa amazinga aphezulu wekhwalithi yamandla ngekusasa.
