Ingcaciso yeMveliso

Okwangoku, icandelo lamandla ligxininisa kakhulu ekugcinweni kwamandla kunye nokunciphisa ilahleko.Ukuqala kulawulo lwamandla ombane kunye namandla asebenzayo, imali eninzi ityaliwe ukuphuhlisa amandla ombane amaninzi kunye nesoftware yolawulo lwamandla asebenzayo.I-VQC, i-tap changer elayishiwe, i-Reactive power compensation shunt capacitor bank kunye nezinye izixhobo, umgangatho wombane uphuculwe ngokufanelekileyo.Nangona kunjalo, ngenxa yokubuyela umva kweendlela zohlengahlengiso lwamandla kunye neengxaki ezinje ngokugqithisileyo, ukugqithisa, kunye nexesha lokuphila ekusebenzeni kwee-capacitors, i-voltage kunye nesoftware yolawulo lwamandla asebenzayo ayinakudlala indima yayo, kwaye ayinakuhlala igcina izikhombisi ezifunekayo zombane kunye nombane. amandla asebenzayo.Inzuzo efunekayo yezoqoqosho kunye nezobugcisa ayinakufezekiswa, kwaye amandla esixhobo awakwazi ukusetyenziswa ngokupheleleyo.

Ijolise ekubuyiseleni umva kwamandla ombane kunye neendlela zohlengahlengiso lwamandla asebenzayo, inkampani yethu iphuhlise uhlobo olutsha lwamandla ombane angaphantsi kunye nesixhobo sohlengahlengiso samandla asebenzayo ngokwesiseko sokufunxa kakhulu itekhnoloji entsha ekhaya nakwamanye amazwe.Umthamo wemveliso utshintshwa ngokulungelelanisa i-voltage kuzo zombini iziphelo ze-capacitor, ezisombulula iingxaki zokugqithisa kunye ne-inrush yangoku ekusebenzeni kwe-capacitor, kunye nokutshintsha ukulungiswa kwe-hysteresis kuhlengahlengiso lwexesha langempela.I-voltage ye-substation kunye ne-reactive power ezenzekelayo isixhobo sokulungelelaniswa kunokuguqula i-capacitor ehambelanayo esisigxina ibe sisixhobo sembuyekezo yamandla eguquguqukayo esebenzayo.Ukuthandwa kunye nokusetyenziswa kwesi sixhobo kunokuphucula ngokufanelekileyo inqanaba lolawulo lwamandla ombane kunye namandla asebenzayo, anokunciphisa kakhulu ilahleko yegridi yombane, ukuphucula umgangatho wamandla, ukuphucula umgangatho wokusebenza okhuselekileyo wezixhobo, ukwandisa inzuzo yezoqoqosho kumashishini okubonelela ngombane. , kunye nokuphucula umthamo wonikezelo lwamandla ngaphandle kokwakha amaziko ombane amatsha.Ukuba negalelo ekusombululeni imeko yangoku yokunqongophala kombane.

umda wesicelo

Iimveliso zifaneleka kakhulu kuwo onke amanqanaba eendawo ezincinci kunye namanqanaba ombane we-6KV ~ 220KV, kwaye zifakwe kwiibhasi ze-6KV / 10KV / 35KV zezikhululo.Iimveliso zisetyenziswa ngokubanzi kwiinkqubo zamandla, isinyithi, amalahle, i-petrochemical kunye namanye amashishini ukuphucula umgangatho wombane, ukwandisa amandla ombane, kunye nokunciphisa ilahleko yomgca.

Umgaqo wesixhobo
I-voltage kunye namandla asebenzayo isixhobo sohlengahlengiso oluzenzekelayo kwisitishi esincinci samkela uqhagamshelo olusisigxina lwe-capacitors ngaphandle kokwenza amaqela, kwaye umthamo wembuyekezo we-capacitor utshintshwa ngokuguqula i-voltage kuzo zombini iziphelo ze-capacitor.Ngokomgaqo we-Q = 2πfCU2, i-voltage kunye ne-C yexabiso le-capacitor ihlala ingatshintshi, kwaye i-voltage kwiziphelo zombini ze-capacitor itshintshiwe.Imveliso yamandla asebenzayo.
Umthamo wayo wokukhupha unokutshintsha ukuchaneka kunye nobunzulu bolawulo lwe-voltage (100% ~ 25%) x Q, oko kukuthi, ukuchaneka kokulungelelaniswa kunye nobunzulu be-capacitors kunokutshintshwa.

Ukuqulunqwa kwesixhobo

Isixhobo sembuyekezo esizenzekelayo esilawula amandla ombane siqulunqwe ikakhulu ngamalungu amathathu, angala ukulawulwa kwamandla ombane, iseti epheleleyo yeecapacitor kunye nombane kunye nephaneli yokulawula amandla asebenzayo.Umzobo 2 ngumzobo osisiseko wesixhobo:

Umlawuli we-voltage: Umlawuli udibanisa i-capacitor kwi-busbar, kwaye utshintshe i-voltage ephumayo ye-capacitor phantsi kwesiseko sokuqinisekisa ukuzinza kwe-voltage ye-busbar, ukwenzela ukuba kuqinisekiswe ukuba umthamo wokuphuma kwe-capacitor uhlangabezana neemfuno zenkqubo.Iphaneli yolawulo lwe-voltage kunye ne-reactive power control: Ngokwe-input current kunye ne-voltage signals, isigwebo sempompo siyenziwa, kwaye imiyalelo ikhutshiwe ukulungelelanisa iitephu eziphambili ze-transformer ye-substation ukulungelelanisa i-voltage ukuqinisekisa izinga lokupasa kombane webhasi.Lungisa i-voltage ye-output ye-voltage regulator ukuze utshintshe umbane osebenzayo we-capacitor.Kwaye inomboniso ohambelanayo kunye nemisebenzi yomqondiso.Umthombo wamandla osebenzayo we-capacitor iseti epheleleyo.
