Ukusetyenziswa kwemizi-mveliso yohlobo lwe-MCR isixhobo esiguqukayo sembuyekezo yamandla asebenzayo

Uhlobo lwe-MCR isixhobo esiguqukayo sembuyekezo samandla asebenzayo sinokusetyenziswa ngokubanzi kule mimandla ilandelayo.

1 Inkqubo yaMandla

1) Isitishi esiqhelekileyo. Ngokongeza i-MCR enomthamo othile ngokwesiseko sebhanki yokuqala ye-capacitor, ukulawulwa okuguquguqukayo kunye nokuqhubekayo kwamandla asebenzayo kwisikhululo esisezantsi kuyafezekiswa, isenzo esithe rhoqo sabaphuli beesekethe siyaphetshwa, izinga lokusetyenziswa kwee-capacitors liphuculwe kakhulu, kwaye amandla factor iphuculwe kakhulu.

2) Isikhululo se-Hub. Ngokufakela isixhobo sembuyekezo yamandla asebenzayo esenziwe sisihluzo se-mcr+fc kwisitishi se-hub, okanye ukongeza i-MCR kwisiseko sesihluzo sokuqala se-FC ukwenza isixhobo sembuyekezo yamandla asebenzayo, ukuphucula ukuzinza kwegridi yamandla kunye nokwandisa umthamo wokuhambisa. umgca.

3) I-reactor ye-voltage ephantsi. Ukutshintsha i-low-voltage reactor ye-substation kwi-MCR ayinayo yonke imisebenzi ye-low-voltage reactor, kodwa inomsebenzi wesixhobo sokubuyisela amandla asebenzayo.

4) Umgca wembuyekezo yamandla asebenzayo. Ngokusebenzisa umlinganiselo ofanelekileyo we-capacitor umthamo kunye nomthamo we-MCR, isenzo se-vacuum contactor sinokuphetshwa ngokusisiseko, ukuthembeka kunye nokhuseleko lwezixhobo kunokuphuculwa, kwaye ubomi benkonzo yezixhobo bunokwandiswa kakhulu.

I-5) Imbuyekezo yamandla asebenzayo kwi-transformer yokusabalalisa. Itekhnoloji ye-TSc+mcr yamkelwa ukuze iphucule kakhulu ukuchaneka kwembuyekezo (0.2 kvar), ukunciphisa kakhulu ukuphindaphindeka kwesenzo sokutshintsha, kunye nokuqinisekisa ngokufanelekileyo ukuba imbuyekezo yamandla esebenzayo ye-transformer yokuhambisa ifikelela kumandla aphezulu we-0 99-1, qonda i-reactive real uqwalaselo lwamandla umaleko wesahlulo sesahlulelo esilinganayo.

2 Inkqubo yeMetallurgical

Ii-rolling Mills kunye ne-arc furnaces zombane zezona zixhaphakileyo ze-reactive impulse loads. Ukusebenzisa i-mcr + fc filter yembuyekezo yamandla aguqukayo anokuphucula kakhulu into yamandla, ukunciphisa ukuguquguquka kwamandla ombane kunye nokuqhwanyaza, ukuphelisa ungcoliseko lwe-harmonic, ukuphucula kakhulu umgangatho wamandla, ukuphucula imeko yokhuseleko lwenkqubo yokubonelela ngombane, ukunciphisa ukusetyenziswa kwamandla ngeyunithi nganye, kunye nokuphucula imveliso. umgangatho.

3 Umzila kaloliwe woMbane

Umzila kaloliwe onombane wamkela imo yonikezelo lwamandla enenqanaba elinye. Ngenxa ye-randomness ye-locomotive, umthwalo we-substation ye-traction ineempawu zesigaba esisodwa somthwalo wempembelelo, kunye nokuguquguquka rhoqo komthwalo kunye nomxholo ophezulu we-harmonic. Akukwazeki ukuqaphela imbuyekezo yomba wamandla aphezulu ngokusebenzisa imo yembuyekezo esisigxina elula. Ukuba i-MCR enomthamo ofanelekileyo ifakwe kwisiseko sesekethe yokucoca iFC enomthamo owaneleyo, imbuyekezo yamandla aphezulu inokufezekiswa nangaliphi na ixesha, ukuguquguquka kombane kunokuncitshiswa kwaye umgangatho wombane unokuphuculwa.

Iimpawu zomthwalo wesigaba esinye sombane kaloliwe zizisa iingxaki ezimandundu zecandelo eliphezulu elingalunganga lolandelelwano kwisitishi saso sombane esingasentla, kwaye ide ikhokelele kwisenzo sokhuseleko olulandelelanayo olubi lwezityalo zombane kunye nezitishi. Ngokufakela izihluzi ze-mcr + fc kwezi zikhululo kunye nokwamkela isicwangciso solawulo lokwahlula isigaba ngokwendlela ye-Steinmetz, le ngxaki ingasonjululwa ngokufanelekileyo, kwaye inokudityaniswa ngokuthe ngqo kwinkqubo yonikezelo lwamandla e-110 kV yembuyekezo, ngaphandle kotyalo-mali. abaguquli abaphakathi, indawo yomgangatho incinci, kwaye ilahleko yezixhobo ngokwayo ingancitshiswa ngaphezu kwe-70%.
