Uhlalutyo lwemeko yazo zonke iicompressor zomoya ezili-9 ezikhubekayo kwiplanti yombane
Akuqhelekanga ukuba i-compressor ye-MCC yomoya ingasebenzi kakuhle kwaye zonke izikhululo ze-compressor zomoya ziyeke.
Isishwankathelo sezixhobo:
Iinjini eziphambili ze-2 × 660MW iyunithi ye-supercritical yeXX Power Plant zonke zikhethwe kwi-Shanghai Electric Equipment.I-injini yomphunga yi-Siemens N660-24.2/566/566, ibhoyila yi-SG-2250/25.4-M981, kunye nejeneretha yi-QFSN-660-2.Iyunithi ixhotyiswe ngeFani eziqulunqiweyo eziqhutywa ngumphunga, iimpompo zokubonelela ngamanzi, kunye ne-9 air compressors zonke ziveliswa ngu-XX Co., Ltd., ezihlangabezana neemfuno zomoya ezixinzelelweyo ze-instrumentation, ukususwa komlotha kunye nokusetyenziswa okuxubileyo kwisityalo sonke. .
Iimeko zokusebenza zangaphambili:
Nge-21:20 ngo-Agasti 22, 2019, iyunithi #1 yeXX Power Plant yayisebenza ngokuqhelekileyo kunye nomthwalo we-646MW, amalahle okugaya amalahle A, B, C, D, kunye no-F ayesebenza, kwaye inkqubo yomoya kunye nomsi yayisebenza. macala omabini, kusetyenziswa indlela esemgangathweni yokusetyenziswa kwamandla kwiplanti.Umthwalo weyunithi #2 uqhuba ngokuqhelekileyo, amalahle amalahle A, B, C, D, kunye no-E ayasebenza, umoya kunye nenkqubo yomsi isebenza kumacala omabini, kwaye i-factory isebenzisa umbane oqhelekileyo.#1~#9 iicompressors zomoya zonke ziyasebenza (imowudi yokusebenza eqhelekileyo), phakathi kwazo #1~#4 izicompressor zomoya zibonelela ngomoya ocinezelweyo we #1 kunye ne #2 iiyunithi, kwaye #5~#9 izicompressor zomoya zibonelela ngokususa uthuli kunye nokuthuthwa kothuthu. Xa usebenzisa inkqubo, isixhobo kunye ne-miscellaneous compressed air contact doors zivulwa i-10%, kunye noxinzelelo lombhobho womoya ocinezelweyo yi-0.7MPa.
#1 iyunithi 6kV icandelo elisetyenzisiweyo kwifektri 1A liqhagamshelwe kunikezelo lwamandla lwe #8 kunye no #9 umoya wokucinezela umoya;Icandelo 1B liqhagamshelwe kunikezelo lwamandla lwe-#3 kunye ne-#4 zomoya zomoya.
#2 iyunithi 6kV icandelo elisetyenzisiweyo kwifektri 2A liqhagamshelwe kunikezelo lwamandla lwe #1 kunye no #2 iicompressor zomoya;icandelo le-2B liqhagamshelwe kunikezelo lwamandla lwe-#5, #6 kunye ne-#7 compressors zomoya.
inkqubo:
Ngo-21:21 ngo-Agasti 22, umqhubi wafumanisa ukuba i-air compressors # 1 ~ # 9 yakhubeka ngaxeshanye, yavala ngokukhawuleza isixhobo kunye neengcango zoqhagamshelwano zomoya ezixubileyo, zamisa ukuthuthwa kothuthu kunye nenkqubo yokususa uthuli ecinezelweyo, kwaye -ukuhlolwa kwendawo kufumene ukuba i-380V Icandelo le-MCC le-compressor yomoya lilahlekelwe amandla.
21:35 Amandla anikezelwa kwicandelo le-MCC le-compressor yomoya, kwaye i- #1 ~ # 6 air compressors iqalwa ngokulandelelana.Emva kwemizuzu emi-3, icompressor yomoya iMCC iphulukana namandla kwakhona, kwaye i #1~#6 air compressors uhambo.Isixhobo sisebenzisa uxinzelelo lomoya olucinezelekileyo lwehla, umqhubi wathumela amandla kwicandelo le-MCC le-compressor yomoya kane, kodwa amandla alahlekile kwakhona emva kwemizuzu embalwa.Icompressor yomoya eyaqalayo yakhubeka ngoko nangoko, kwaye uxinzelelo lwenkqubo yomoya ecinezelweyo ayikwazanga kugcinwa.Sifake isicelo sokuthunyelwa kwemvume kwiiyunithi zogqithiselo #1 kunye ne#2 Umthwalo wehle waya kuma-450MW.
Ngo-22:21, isixhobo esicinezelekileyo somoya saqhubeka sihla, kwaye ezinye iingcango zokulungisa umoya azizange ziphumelele.Ezona ngcango ziphambili kunye nokufudumeza umphunga wobushushu obuphantsi kwamanzi eminyango yeyunithi #1 yavalwa ngokuzenzekelayo.Iqondo lobushushu eliphambili lomphunga lenyuka laya kutsho kuma-585°C, kwaye iqondo lokufudumeza ngokutsha umphunga lonyuke laya kutsho kuma-571°C.℃, ubushushu bodonga lwebhoyila lugqithisa i-alam yomda, kwaye incwadi yebhoyila ye-MFT kunye neyunithi inqanyulwe kwangoko.
Nge-22:34, isixhobo esicinezele uxinzelelo lomoya lwehla lwaya kutsho kwi-0.09MPa, umnyango olawula umphunga we-shaft weyunithi #2 uvalwe ngokuzenzekelayo, ukubonelelwa komphunga we-shaft kuye kwaphazamiseka, uxinzelelo lweyunithi lwanyuka, kunye “noxinzelelo oluphantsi lokukhupha umphunga. ubushushu buphezulu” isenzo sokhuseleko (jonga umfanekiso oqhotyoshelweyo wesi-3), iyunithi ivaliwe.
22:40, vula kancinane i-bypass ephezulu yeyunithi #1 kunye nomphunga oncedisayo.
Ngo-23:14, ibhoyila # 2 iyacinywa kwaye ivuleleke kwi-20%.Ngo-00: 30, ndaqhubeka ndivula i-valve yecala eliphezulu, kwaye ndafumanisa ukuba imiyalelo yanda, impendulo yahlala ingatshintshi, kwaye umsebenzi wezandla wendawo wawungavumelekanga.Kuye kwaqinisekiswa ukuba undoqo wevalve yecala eliphezulu ubambekile kwaye kufuneka uqhawulwe kwaye uhlolwe.Incwadi ye-MFT ye-#2 yebhoyila.
Ngo-8:30, i#1 yebhoyila iyatshiswa, ngo-11:10 i-injini yomphunga iyakhawuleza, kwaye ngo-12:12 iyunithi ye-#1 idityaniswe kwigridi.
Iyaqhuba
Ngo-21:21 nge-22 ka-Agasti, iicompressors zomoya #1 ukuya kwi-#9 zikhutshiwe ngaxeshanye.Nge-21:30, ukugcinwa kombane kunye nabasebenzi bokugcina ubushushu baya kwindawo ukuze bahlolwe kwaye bafumanisa ukuba ukutshintshwa kwamandla okusebenza kwecandelo le-MCC le-compressor yomoya yakhubeka kwaye ibhasi yaphelelwa ngamandla, okubangela ukuba zonke i-9 air compressors zilahlekelwe amandla e-PLC kunye nazo zonke. iicompressors zomoya zikhutshiwe.
21:35 Amandla anikezelwa kwicandelo le-MCC le-compressor yomoya, kunye ne-air compressors #1 ukuya ku-#6 iqaliswe ngokulandelelana.Emva kwemizuzu emi-3, i-MCC ye-compressor yomoya ilahlekelwa amandla kwakhona, kunye ne-air compressors #1 ukuya kwi-#6 uhambo.Emva koko, iswitshi yamandla esebenza ngecompressor ye-MCC kunye nesitshixo samandla esigciniweyo sizanyiwe amatyeli aliqela, kunye nebar yebhasi yecompressor yeMCC yakhubeka emva kwemizuzu embalwa emva kokutshaja.
Ukujonga ukususwa kothuthu kwikhabhinethi yolawulo lwe-DCS ekude, kwafunyaniswa ukuba igalelo lokutshintsha imodyuli ye-A6 yayivutha.Ubungakanani begalelo (24V) lomjelo we-11 wemodyuli ye-A6 yalinganiswa kwaye i-220V yangoku eguqukayo yangena.Khangela ngakumbi ukuba intambo yofikelelo yetshaneli ye-11 yemodyuli ye-A6 yayiyingxowa yelaphu engaphezulu kwendawo yokugcina uthuthu lwe-#3.Umqokeleli wothuli wokukhupha ingxelo yengxelo yokusebenza kwefeni.Ukuhlolwa kwendawo #3 I-loop yempendulo yesignali yokusebenza kwibhokisi yokulawula i-fan yokukhupha uthuli yebhokisi ecocekileyo yokuqokelela uthuli idityaniswe ngokungalunganga kwi-220V AC yolawulo lombane kwibhokisi, ibangela ukuba amandla e-220V AC ageleze kwimodyuli ye-A6. ngomgca wengxelo yengxelo yokusebenza kwabalandeli.Iziphumo zexesha elide zombane we-AC, Ngenxa yoko, ikhadi aliphumelelanga kwaye latshiswa.Abasebenzi bezolondolozo bagweba ukuba umbane kunye nokutshintsha imodyuli yokuphuma kwemodyuli yekhadi kwikhabhinethi inokusebenza kakubi kwaye ayikwazi ukusebenza ngokuqhelekileyo, okubangelwa ukukhubeka rhoqo okungaqhelekanga kombane I kunye nokutshintshwa kwamandla e-II yecandelo le-MCC ye-compressor yomoya.
Abasebenzi bezolondolozo basuse umgca wesibini owabangela ukuba i-AC ihambe ngaphakathi. Emva kokutshintsha imodyuli ye-A6 etshisiweyo, ukuhamba rhoqo kokunikezelwa kwamandla I kunye nokutshintshwa kwamandla II kwecandelo le-MCC le-compressor yomoya yanyamalala.Emva kokubonisana nabasebenzi bezobugcisa bomvelisi we-DCS, kwaqinisekiswa ukuba le nto ikhona.
22:13 Amandla anikezelwa kwicandelo le-MCC le-compressor yomoya kwaye i-compressor yomoya iqaliswe ngokulandelelana.Qala umsebenzi wokuqalisa iyunithi
Imiba eveziweyo:
1. Itekhnoloji yolwakhiwo lweziseko zophuhliso ayifani.I-XX Electric Power Construction Company ayizange idale i-wiring ngokwemizobo, umsebenzi wokulungisa umonakalo awuzange uqhutywe ngendlela engqongqo kunye neenkcukacha, kwaye umbutho wokulawula awuphumelelanga ukugqiba ukuhlolwa kunye nokwamkelwa, okwabeka iingozi ezifihliweyo ekusebenzeni ngokukhuselekileyo. iyunithi.
2. Uyilo lonikezelo lwamandla olawulo alunangqiqo.Uyilo lwe-air compressor PLC yolawulo lonikezelo lwamandla alunangqiqo.Zonke izixhobo zokulawula icompressor zomoya PLC zithathwa kwicandelo elifanayo lebhasi, okukhokelela kunikezelo lwamandla olunye kunye nokuthembeka okulambathayo.
3. Uyilo lwenkqubo yomoya ecinezelweyo alunangqiqo.Ngexesha lokusebenza okuqhelekileyo, zonke i-9 air compressors kufuneka zisebenze.Ayikho i-compressor yomoya egcinayo kwaye izinga lokusilela ekusebenzeni kwecompressor liphezulu, nto leyo ibeka ingozi enkulu yokhuseleko.
