Kwinkqubo yegridi yamandla yale mihla, ukudityaniswa kwemithwalo emikhulu engasebenzisi migca emikhulu efana neziko zombane ze-arc, ii-mill-rolling mill, iihoist, iilocomotives zombane, kunye neefama zomoya kuzise uthotho lweziphumo ezibi kwigridi yamandla. .igridi.Ezi ziphumo ezibi zibandakanya ukuguquguquka kwamandla ombane, ukulahlekelwa kwamandla kunye ne-harmonics, enokubangela ukungazinzi kwenkqubo kunye nokungasebenzi kakuhle.Ukuze kusonjululwe ezi ngxaki, izixhobo zokucoca amandla aguqukayo akwi-high-voltage asebenzayo ziye zayimfuneko ekugcineni uzinzo kunye nokuthembeka kwegridi yamandla.
IIsixhobo sokucoca amandla ombane aphezulu aguqukayo asebenzayoyenzelwe ngokukodwa ukunciphisa imiphumo emibi ebangelwa yimithwalo engabonakaliyo kunye nephezulu yokusetyenziswa kwamandla.Ezi zixhobo zisebenzisa itekhnoloji ye-elektroniki yamandla aphambili ukubonelela ngembuyekezo yamandla asebenzayo ngokukhawuleza nangokuchanekileyo, ukucinezelwa kwe-harmonic kunye nolawulo lombane.Ngokwenza njalo, umgangatho wamandla kunye nokusebenza kakuhle kwegridi kuphuculwe, kuqinisekiswe ukunikezelwa kwamandla angaphazamisekiyo kunye nokuthembekileyo kwiindawo ezahlukeneyo zoshishino kunye nezorhwebo.
Iifama ze-arc zombane, i-high-power rolling mill, ii-hoists, ii-locomotives zombane kunye neefama zomoya zibalulekile kwimisebenzi yemizi-mveliso yanamhlanje, kodwa ukudibanisa kwabo kwigridi kunokubeka imingeni ebalulekileyo.Ukungahambelani kunye nokuphazamiseka kwale mithwalo kunokukhokelela ekungazinzini kombane, ukuguquguquka kwamandla kunye nokuphazamiseka kwe-harmonic, konke oku kunokuchaphazela kakubi igridi kunye nezixhobo zombane ezixhunyiwe.Isixhobo sokucoca amandla aguqukayo aphezulu asebenzayo sinciphisa ngempumelelo ezi ngxaki kwaye siqinisekisa uzinzo kunye nokuthembeka kwegridi yamandla.
Ukongeza, ukudityaniswa kwemithombo yamandla ahlaziyekayo efana neefama zomoya zongeza ubunzima begridi.Ukuphazamiseka kokuveliswa kwamandla omoya kunokukhokelela kuguquguquka kwamandla ombane kunye nokungalingani kwamandla, kufuna imbuyekezo enamandla asebenzayo kunye nezisombululo zolawulo lombane.Isixhobo sokucoca amandla ombane oguqukayo oguqukayo wembuyekezo sinokulawula ngokufanelekileyo kwaye sizinzise amandla ombane wegridi, siqinisekise ukudityaniswa kwegridi engenamthungo yamandla ahlaziyekayo, kunye nokunciphisa impembelelo kuzinzo lulonke lwegridi.
Isishwankathelo, izixhobo zokucoca imbuyekezo ye-high-voltage dynamic reactive idlala indima ebalulekileyo ekugcineni uzinzo nokuthembeka kweegridi zamandla zanamhlanje.Ngokubonelela ngembuyekezo yamandla asebenzayo ngokukhawuleza nangokuchanekileyo, ukunyanzeliswa kwe-harmonic kunye nokulawulwa kwamandla ombane, ezi zixhobo zinokunciphisa ngokufanelekileyo iziphumo ezibi zomthwalo ongewona mgca kunye nophezulu wamandla kunye nemithombo yamandla ahlaziyekayo.Ngokukhula okuqhubekayo kwemfuno yamandla, ukubaluleka kwe-high-voltage dynamic reactive imbuyekezo yokucoca izixhobo zokucoca ukuqinisekisa ukuzinza kunye nokusebenza kakuhle kwegridi yamandla kuyabonakala.
