Isishwankathelo
Kwiminyaka yakutshanje, uqoqosho lwaseTshayina luqhubekile nophuhliso olukhawulezayo, iingxaki zamandla ziye zanda ngakumbi nangakumbi ukuba zibe yeyona ngqiniba yophuhliso loshishino, kunye nokunyuka ngokukhawuleza kwamaxabiso ombane, ukhuphiswano oluqatha kwimarike yasekhaya, ukongiwa kwamandla kuye. ibe yeyona ngxaki iphambili ejongene nophuhliso lwamashishini amaninzi, ngakumbi ukusetyenziswa kwamandla kumashishini amakhulu ngokwentelekiso afana nepetroleu-m, imichiza, amayeza, isinyithi, imveliso, ukhuseleko lokusingqongileyo, umasipala-pal kunye namanye amashishini.Ngokwedatha, umthamo opheleleyo weenjini zombane eziphezulu nezisezantsi e-China zingaphezulu kwe-35000MW, uninzi lwayo yimithwalo yempompo yabalandeli, kwaye uninzi lwayo lusebenza kusetyenziso lwamandla aphezulu kunye nokusebenza okuphantsi.
I-fan jikelele, inkqubo yempompo ininzi yevalve yokulungelelanisa ukuhamba kwamanzi okanye uxinzelelo, ukuphazamisa lo mmiselo kukunyusa ilahleko yombhobho wombhobho, udle amandla amaninzi kwiindleko, ngoko ke, ngokungenakuphepheka kubangela inkunkuma yamandla ombane.Kwaye ngenxa yokuba uyilo, inkqubo iyilwe ngokomthwalo ophezulu, ekusebenzeni okwenyani, ixesha elininzi inkqubo ayinakwenzeka ukuba iqhube kwimeko yomthwalo ogcweleyo, kukho i-surplus enkulu, ngoko kukho amandla amakhulu okonga amandla. .
Ukusebenzisa isixhobo sokulawula isantya sokuguqula isantya se-KD600, ngokuguqula isantya sefeni, ukuze utshintshe umthamo womoya wefeni ukuze uhlangabezane neemfuno zenkqubo yokuvelisa, kwaye ukusetyenziswa kwamandla okusebenza yeyona nto isindisayo, eyona nzuzo iphezulu ebanzi.Ke ngoko, ukulawulwa kwezantya eziguquguqukayo siskimu esisebenzayo nesifanelekileyo solawulo lwesantya, esinokuqonda ukulawulwa kwesantya esingenanyathelo somqhubi, kwaye sinokwenza lula inkqubo yolawulo lwe-loop evaliweyo ukufezekisa uxinzelelo oluqhubekayo okanye ulawulo lokuqukuqela rhoqo.
Uguqulo rhoqoUmgaqo wesantya somgaqo-nkqubo wokugcina amandla
Ngokomgaqo wobuchwephesha bolwelo, ubudlelwane phakathi kombane we-shaft P kunye nomthamo womoya Q kunye noxinzelelo lomoya H wefeni eqhutywa yimoto yokufakelwa kolu hlobo lulandelayo:
“I-Q * H Xa isantya semoto sitshintsha ukusuka ku-n1 ukuya ku-n2, ubudlelwane phakathi kwe-Q, H, P kunye nesantya simi ngolu hlobo lulandelayo:
Kuyabonakala ukuba umthamo womoya u-Q ulingana nesantya n semoto, kwaye i-shaft efunekayo amandla P ilingana netyhubhu yesantya.Ngoko ke, xa i-80% yomthamo womoya olinganisiweyo ifunekayo, ngokulungelelanisa isantya semoto ukuya kwi-80% yesantya esilinganisiweyo, oko kukuthi, ukulungelelanisa i-frequency ukuya kwi-40.00Hz, amandla afunekayo aya kuba yi-51.2% kuphela ye-original.
Njengoko kubonisiwe kuMzobo (1), umphumo wokonga amandla emva kokwamkela ukulawulwa kwesantya esiguquguqukayo sihlalutywa kwi-curve yokusebenza kwefeni.
Xa umthamo womoya ofunekayo uyancipha ukusuka kwi-Q1 ukuya kwi-Q2, ukuba indlela yokulungelelanisa i-damper yamkelwe, ukuxhathisa kwenethiwekhi yombhobho kuya kwanda, umbhobho womnatha we-charact-eristic curve uya kunyuka, indawo yokusebenza yenkqubo iya kutshintsha ukusuka kwinqanaba. A ukuya kwindawo entsha yokusebenza ye-B, kunye ne-shaft power efunekayo i-P2 i-pro-portionalto indawo ye-H2 × Q2.Ukuba imowudi yokulawula isantya iyamkelwa, isantya se-fan sihla ukusuka ku-n1 ukuya ku-n2, iimpawu zenethiwekhi azitshintshi, kodwa i-curve ye-fan ye-fan iya kuhamba phantsi, ngoko imeko yayo yokusebenza ishukunyiswa ukusuka ku-A ukuya ku-C. efunekayo shaft amandla P3 ngokomlinganiselo kummandla HB×Q2.Ngokwethiyori, i-shaft power Delt (P) igcinwe ilingana nommandla we (H2-HB) × (CB).
Ukuqwalasela ukucuthwa kokusebenza kakuhle emva kokunciphisa kunye nokulahlekelwa okongeziweyo kwesixhobo sokulawula isantya, ngokusebenzisa izibalo eziphathekayo, abalandeli banokugcina amandla ngokulawula isantya sokulawula ukuya kwi-20% ~ 50%.
Inzuzo yolawulo lwesantya esiguquguqukayo
- Amandla ombane wecala lomnatha aphuculwe: xa i-motor yokuqala iqhutywa ngokuthe ngqo ngamaza ombane, amandla ombane amalunga ne-0.85 kumthwalo opheleleyo, kwaye eyona nto isebenzayo yamandla iphantsi kakhulu kune-0.8.Emva kokwamkela inkqubo yokulawula isantya sokuguqula isantya, indawo yamandla kwicala lamandla inokunyuswa ukuya kuthi ga kwi-0.9, kwaye amandla asebenzayo anokwehliswa kakhulu ngaphandle kwesixhobo sembuyekezo yamandla asebenzayo, esinokuhlangabezana neemfuno zegridi yamandla. kwaye ukonga ngakumbi iindleko zokusebenza zezixhobo ezinyukayo.
- Ukusebenza kwezixhobo kunye neendleko zokulondoloza zinciphile: Emva kokusetyenziswa kohlengahlengiso lokuguqulwa kwamaza, ngenxa yokulungelelaniswa kwesantya semoto ukufezekisa ukugcinwa kwamandla, xa izinga lomthwalo liphantsi, isantya semoto siyancipha, izixhobo eziphambili kunye nezixhobo ezincedisayo ezihambelanayo. ezinje ngeebheringi ezinxiba ngaphantsi kunangaphambili, umjikelo wolondolozo unokwandiswa, ubomi bokusebenza kwezixhobo buyandiswa;Kwaye emva kokuguqulwa kokuguqulwa, ukuvulwa kwe-damper kunokufikelela kwi-100%, kwaye umsebenzi awukho phantsi koxinzelelo, olunokunciphisa kakhulu ukugcinwa kwe-damper.Ekusebenzeni kwesiguquli esijikelezayo, kufuneka kuphela uthuli rhoqo isiguquli esijikelezayo, ngaphandle kokuyeka, ukuqinisekisa ukuqhubeka kwemveliso.Ngeemfuno zemveliso, lungisa isantya se-fan, kwaye emva koko ulungelelanise umthamo womoya we-fan, ongahambelani kuphela neemfuno zenkqubo yokuvelisa, kodwa unciphisa kakhulu umsebenzi.Emva kokwamkela itekhnoloji yokuguqula isantya solawulo lwesantya, ukunxitywa koomatshini kuncitshisiwe, umthwalo wolondolozo uyancitshiswa, kwaye iindleko zokugcinwa ziyancipha.
- Emva kokuba isixhobo esilawula isantya sokuguqula isantya sisetyenzisiwe, i-motor inokuthamba-iqaliswe, kwaye yangoku ayidluli amaxesha angama-1.2 ombane olinganisiweyo wemoto xa uqala, ngaphandle kwempembelelo kwigridi yamandla, kunye nobomi benkonzo yemoto. yandisiwe.Kulo lonke uluhlu olusebenzayo, i-motor inokuqinisekisa ukusebenza kakuhle, ukunciphisa ilahleko, kunye nokunyuka kobushushu obuqhelekileyo.Ingxolo kunye nokuqala kwangoku kwefeni kuncinci kakhulu xa iqala, ngaphandle kokungcangcazela okungaqhelekanga kunye nengxolo.
- Xa kuthelekiswa nenkqubo endala, inverter inenani lemisebenzi yokukhusela efana ne-overcurrent, isiphaluka esifutshane, i-overvoltage, i-undervoltage, ukungabikho kwesigaba, ukunyuka kweqondo lokushisa, njl., Ukukhusela ngcono i-motor.
- Ukusebenza okulula kunye nokusebenza kakuhle.Iiparamitha ezinje ngevolumu yomoya okanye uxinzelelo zinokusetwa kude ngekhompyuter ukufezekisa ummiselo okrelekrele.
- Ukukwazi ukuziqhelanisa nokuguquguquka kwamandla ombane kwigridi yombane yomelele, uluhlu olusebenzayo lwamandla ombane lubanzi, kwaye inkqubo inokusebenza ngokuqhelekileyo xa umbane wegridi yamandla uguquguquka phakathi kwe-15% kunye +10%.
