Izimo zokuklama
Izimo zamandla
Ngokusho komthwalo kagesi wephrojekthi, inkampani yethu ihlongoza ukuhlinzeka ngogesi ongu-18 MW amasethi ejeneretha yegesi+6 amasethi e-booster kanye ne-transformer skid (i-tpye equkethwe, ukuze ikhuphuke ibe yi-10 kV) +1 isethi ye-sub-section post engu-10 kV +1 isethi ye-step-down transformer skid. Ngokuphakela isethi engu-18 yejeneretha engu-1MWgas esethwe kuma-transformer ohlobo lwebhokisi angu-6 ngokulandelana, i-voltage engu-400 V ikhushulwa ibe yi-10 kV bese ihlanganiswa ibe yi-sub-section post engu-10 kV, bese i-sub-section post inikeza amandla kwi-compressor yokuqandisa. Ngesikhathi esifanayo, ingxenye yamandla kagesi ikhishwa kwi-step-down transformer skid, amandla kagesi angu-400V asatshalaliswa yi-step-down transformer skid.
Ngokusho komthwalo wamandla wangempela wephrojekthi, isethi engu-1 ~ 2 yamasethi ejeneretha kagesi angu-1MW (futhi aziwa ngokuthi I-genset yegesi engu-1000kw） ingavalwa, engashintshwa ukuze isetshenziswe ku ukulungiswa kwejeneretha okulandelayoKunconywa isethi yohlelo lokulawula isiteshi esikude kulo msebenzi, olungabona ukusebenza okuthile kwesethi yejeneretha egumbini lokulawula eliphakathi. Isethi yegesi yomoya ongcolile yejeneretha yegesi isetshenziselwa ukusetshenziswa kokushisa okulahliwe, kanti iyunithi engu-1MW ifakwe i-DN300 flue gas header kanye ne-flange.
Ukunikezwa kwamandla kagesi okukodwa okunamandla aphezulu okunikezwa ngumsebenzisi yi-10KV±5% 50HZ±0.5HZ, uhlelo lwezintambo ezintathu olunezigaba ezintathu, futhi iphuzu elingathathi hlangothi alisekelwe. Kufakwa ukungcwatshwa okuqondile kwezintambo ezinamandla aphezulu ezivikelwe.
Ububanzi bomklamo
Iqembu B linesibopho sokuklama isiteshi esincane esingu-10KV/0.4KV kanye nohlelo lokuphakelwa kwamandla nokusabalalisa lwesitshalo sokuncibilikisa uketshezi (ngekhanda lenqwaba elamukela amandla lekhabhinethi engenayo engu-10KV njengomngcele), linesibopho sokuklama imidwebo yesistimu kagesi enamandla aphezulu naphansi, imidwebo yeskimu yokulawula kagesi, kanye nomdwebo weTheminali, umdwebo wokwakheka kwereferensi yemishini kagesi enamandla aphezulu naphansi, kanye nomklamo webhokisi lokusebenza lendawo (ikholomu). Ukusatshalaliswa kwamandla kwesitshalo sonke, ukuphakelwa kwamandla kwephampu kagesi eyinhloko yesistimu yokuvikela umlilo, ukukhanya komphakathi kwesitshalo sonke, uhlelo lokukhanyisa isakhiwo, ukuphakelwa kwamandla okuphuthumayo kwamajeneretha kadizili, kanye namabhokisi okusabalalisa okulungisa (amakhabhinethi) akuzona izinto ezidingekayo kulo mklamo.
Izimiso zokuklama nokukhetha
(1) Imishini yokulawula kagesi yalesi sitshalo sokuphuza uketshezi kufanele ilwele ukuba ethembekile, ephephile, ethuthukisiwe futhi elula ukuyisebenzisa ngesisekelo sokuhlangabezana nezimo zokuklama kanye nezidingo zenqubo.
(2) Ukulawula, ukulinganisa, ukuvikela kanye nesignali yazo zonke izinjini kanye nemishini kagesi kufanele kubekwe ngokuhambisana nemithethonqubo kazwelonke efanele.
(3) Uhlelo lwe-0.4KV efektri luklanywe njengesekethe ephindwe kabili.
(4) Yonke imishini kagesi esetshenziswayo ifakwe amabhokisi okulawula ukusebenza kwendawo (amakhabethe). Izinga lokuvikela ukuqhuma kwemishini kagesi yendawo ezindaweni ezingaqhumi liklanywe ngokwe-DⅡBT4, kanti izinga lokuvikela kwalo lingu-IP65; izinga lokuvikela langaphandle lemishini yokulawula kagesi ezindaweni ezingaqhumi yi-IP54 Design, izinga lokuvikela lemishini yokulawula kagesi yangaphakathi liklanywe ngokwe-IP30.
(5) Uma izinjini eziphezulu neziphansi ziqalwa, i-voltage yebhasi kufanele ihlangabezane okungenani nama-85% we-voltage elinganisiwe. Ngenxa yalesi sizathu, izinjini ezine-voltage ephansi ezinamandla alinganisiwe angu-75KW nangaphezulu ziyadingeka ukuqala ngesiqalisi esithambile; injini eyinhloko ye-refrigerant compressor isebenzisa idivayisi yokuqalisa ethambile ene-voltage ephezulu.
(6) Uhlelo olusebenzisa amandla aphezulu lusebenzisa idivayisi yokuvikela ehlanganisiwe yekhompyutha encane ukuze kufezwe imisebenzi efana nokuvikelwa kokudluliselwa kanye nokulinganisa.
(7) Ukusebenza, ukuvikelwa kanye namandla esignali eswitshi se-high-voltage switchgear kusebenzisa ugesi we-DC we-DC220V, ovela esikrinini se-DC sebhethri le-lead-acid elingenayo i-maintenance, futhi ugesi we-DC wabelwana nohlelo lwe-10KV.
(8) Isimo sokusebenza kwemishini kagesi yemishini yonke yokuncibilikisa uketshezi kanye nesignali yamanje yemoto engu-30KW nangaphezulu kungena ohlelweni lwe-DCS ukuze luboniswe, futhi yonke imishini kagesi yemishini yenqubo ingaqalwa futhi imiswe ku-DCS egumbini lokulawula eliphakathi, futhi ingaqalwa futhi imiswe endaweni. Izinkinobho zokumisa eziphuthumayo zama-compressor esiqandisini, ama-compressor egesi okudla, amaphampu amanzi ajikelezayo, njll. Zisethwe egumbini lokulawula eliphakathi.
(9) Idivayisi yokuvikela ephelele ye-microcomputer yesistimu ye-voltage ephakathi isatshalaliswa futhi ifakwe kukhabhinethi ngayinye yokushintsha, bese kusetha uhlelo lokuqapha ingemuva le-microcomputer. Uhlelo lokuqapha ingemuva lesistimu ye-10KV lwabelwana nohlelo lokuqapha ingemuva le-35KV, futhi akukho ukusethwa okuhlukile okudingekayo. Qaphela ukuqapha amapharamitha okusetshenziswa kwamandla esitshalo sokuphuza uketshezi, ukuqapha ikhwalithi yokunikezwa kwamandla egridi, ukulawula kude kwemishini, ukulinganisa kanye nemisebenzi ye-alamu, ukuphathwa kwemibiko, ukuhlaziywa kwemikhuba, izibalo, kanye nokuqoshwa kwawo wonke amapharamitha kagesi esitshalo sokuphuza uketshezi.
(10) Uhlelo lwe-10KV olune-voltage ephezulu lufakwe idivayisi yesinxephezelo samandla asebenzayo asebenzayo aphakathi nendawo ukuze kwenziwe isinxephezelo samandla asebenzayo emishinini enamandla anamandla aphezulu. Ngemva kwesinxephezelo, i-power factor yebhasi inkulu kune-0.95. Uhlelo lwe-low voltage lufakwe idivayisi yesinxephezelo samandla asebenzayo angashintshashintshi angathintani ukuze kwenziwe isinxephezelo samandla asebenzayo ebhasini le-380V. Ngemva kwesinxephezelo, i-power factor yebhasi inkulu kune-0.95.
