Emizamweni yokunciphisa ukusetshenziswa kwamandla kanye nokukhishwa kwegesi, amathimba okuphatha isikhungo aphendukela ekulungiseni isici samandla ukuze kuthuthukiswe ukusetshenziswa kwamandla okusebenza.Ukulungiswa kwezinto zamandla kudlala indima ebalulekile ekulawuleni amandla kagesi, isici samandla, kanye nokusimamisa amasistimu kagesi kagesi.Obunye bobuchwepheshe obubalulekile obusetshenziswa kule nqubo ukusetshenziswa kwe-Static Var Generators (SVGs).
Ama-SVG, aziwa nangokuthi ama-Static Synchronous Compensators (STATCOM), angamadivayisi aklanyelwe ukulawula i-voltage, isici samandla, kanye nokusimamisa igridi kagesi.Lawa madivayisi asebenzisa isiguquli somthombo kagesi ukuze afake amandla asebenzayo kugridi, anikeze isinxephezelo samandla asebenza ngokushesha asebenza ngokushesha.Lesi sinxephezelo sisiza ukuthuthukisa ikhwalithi yamandla, ukuvimbela ukungazinzi kwamandla kagesi, nokwandisa ukusetshenziswa kwamandla ezikhungweni.
Ukunciphisa ukucwayiza okubangelwa ukushintshashintsha kwamandla kagesi kungenye inzuzo ebalulekile ehlinzekwa ama-SVG.I-Flicker isho ukushintshashintsha okubonakalayo kokukhanyisa noma okukhiphayo kwesibonisi, okungabangelwa ukuhluka kwamandla kagesi.Lokhu kushintshashintsha kwamandla kagesi kuvame ukuba umphumela wokushintsha okungazelelwe kwesidingo somthwalo, futhi kungaba nomthelela omkhulu ekusebenzeni okuphelele kanye nekhwalithi yamasistimu kagesi.Ama-SVG, ngamakhono awo asebenzayo wokujova amandla, asiza ukuzinzisa i-voltage futhi anciphise ukucwayiza, aqinisekise indawo engaguquki nenethezekile yabahlali besikhungo.
Ukusebenzisa ama-SVG okulungiswa kwezinto zamandla akusizi nje kuphela ekuthuthukiseni ikhwalithi yamandla kodwa kuletha amandla amakhulu nokonga kwezindleko.Ngokuthuthukisa isici samandla, izindawo zinganciphisa ukulahleka kwamandla, okuholela ekunciphiseni ukusetshenziswa kwamandla kanye nezindleko eziphansi zezinsiza.Njengoba izindleko zamandla zikhuphuka ngokungaguquki, ubuchwepheshe bokulungisa isici samandla buvumela amaqembu aphethe isikhungo ukuthi enze izinyathelo ezibalulekile ekuqhubekeni nokusebenza ngendlela eyongayo.
Ama-SVG awagcini nje ngokunikeza izinzuzo zezomnotho nezemvelo, kodwa futhi athuthukisa ukuthembeka okuphelele nokusebenza kahle kwezinhlelo zamandla kagesi.Ngokuzinzisa i-voltage, ukulawula isici samandla, nokuphatha ama-harmonics, ama-SVG asiza ekwehliseni ukuguquguquka kwamandla, anciphise ukucindezelwa kwemishini, futhi anciphise ubungozi bokuhluleka kwamandla.Lokhu ekugcineni kunomthelela ekwandiseni isikhathi, ukukhiqiza okuthuthukisiwe, kanye nokuthuthukiswa kokusebenza isikhathi eside kwezinhlelo zokusebenza ezihlukene zesikhungo.
Sengiphetha, ukunaka ukulungiswa kwesici samandla ngokusebenzisa ama-Static Var Generators (SVGs) kunamandla amakhulu okunciphisa ukusetshenziswa kwamandla kanye nokukhipha amandla ezikhungweni.Lawa madivayisi alawula ngempumelelo i-voltage, azinzisa isistimu kagesi, futhi athuthukise ikhwalithi yamandla.Ngokuphatha kahle amandla asebenzayo, ukulawula ukuhambisana, nokunciphisa ukucwayiza, ama-SVG akhulisa ukusetshenziswa kwamandla, athuthukise ukusebenza kahle kokusebenza, futhi akhuthaze izinqubo zokuphatha indawo ezizinzile.Ukutshala imali kubuchwepheshe bokulungisa izinto zamandla akuzuzisi nje imvelo kuphela kodwa kuletha ukonga okukhulu kwezindleko futhi kuthuthukisa ukwethembeka ezinhlelweni zamandla kagesi.
