Ubunjiniyela bukagesi,kusukela ekwenzekeni kuye ekufakweni kukagesi

Sithatha wonke umsebenzi kagesi wefekthri njengento eyodwa: izinhlu zomthwalo nokuhlolwa kwesidingo, ugesi ongenayo nosayizi we-transformer, isakhiwo sokusabalalisa, ifilosofi yokuvikela kanye ne-earthing. Lapho uhlelo selukhona, silubuyekeza ngokomthwalo okhona namuhla kunokuba silubheke njengoba lwaklanywa, futhi sisho ngokusobala lapho lungasasebenzi khona.

• Ukuhlolwa komthwalo, ama-demand factor nosayizi we-transformer
• Isakhiwo sokusabalalisa kwe-HT ne-LT, kanye ne-single line elandela kuso
• Ifilosofi yokuvikela nokuhlanganiswa kwayo, okwenziwe imodeli ku-ETAP
• Umklamo we-earthing nowokuvikela kumbani, usekelwa ukukalwa kwe-soil resistivity
• Izincazelo zobuchwepheshe nokuhlolwa kwezobuchwepheshe kwamathenda
• Ukwengamela endaweni yomsebenzi, nokuba ufakazi wokuhlolwa lapho udinga amanye amehlo

I-generator, i-governor, i-excitation ne-switchyard kuphathwa njengohlelo olulodwa, ngoba esethini encane yamandla amanzi kuziphatha njengento eyodwa. Siqalise ukusebenza kwamafekthri ezindaweni eLadakh nase-Arunachal Pradesh, lapho ukubuyela khona kubalwa ngezinsuku, ngakho uhlelo lokuqaliswa kokusebenza nohlu lwezingxenye zokushintsha kubaluleke njengemidwebo.

• Ukuvikelwa kwe-generator, i-excitation nokulawulwa kwevolthi okuzenzakalelayo
• Ukuxhumanisa i-governor ye-turbine nokulawulwa kweyunithi
• Isakhiwo se-switchyard, ukuvikela nokukala
• Izinsiza zesiteshi: ukusabalalisa kwe-LT, izinhlelo ze-DC, usayizi webhethri nowesishaji
• Ukuvumelanisa nokuxhuma kugridi
• Ukuqaliswa kokusebenza ezindaweni ezikude, kuhlelwe ngendlela yokufinyelela onayo ngempela

Izakhiwo, ama-schematic, izibalo nezinhlelo zokuvikela, kukhishwa njengephakeji ukhontileka angakha ngayo, umhloli angayivuma, nethimba lakho lokunakekela elisakwazi ukuyifunda eminyakeni eyishumi ezayo. Izibalo ziyaboniswa, hhayi imiphumela yazo kuphela, ukuze isisekelo sesinqumo sikwazi ukuhlolwa kunokuba nje sethenjwe.

• Ama-substation afika ku-765 kV, e-air-insulated nawe-gas-insulated
• Umklamo kagesi wamandla amanzi, we-coal washery, wokuphathwa kwezimpahla nowamafekthri okucubungula
• Ukwenziwa kwemodeli yohlelo lwamandla ku-ETAP nokuhlanganiswa okugcwele kokuvikela
• Izilungiselelo zama-numerical relay, zikhishwe njengeshejuli elilungele ukusetshenziswa
• Imidwebo iyabuyekezwa iphinde ikhishwe njengoba izimo endaweni yomsebenzi zishintsha

I-switchyard yilapho ifekthri ihlangana khona negridi, futhi yahlulelwa ngezinsuku ezimbili: usuku efakwa ngalo ugesi nosuku okumele isuse ngalo iphutha. Siyithatha kusukela esakhiweni se-bay nasezikhaleni, sidlule ohlelweni lwe-busbar, ekuvikeleni nase-earth mat, bese sihlala endaweni yomsebenzi ukuze kumiswe, kwenziwe i-pre-commissioning nokufakwa kukagesi. Kungaba e-air-insulated noma e-gas-insulated, iyadi entsha noma ukwelulwa kwaleyo engeke ivalwe, ubunjiniyela buyafana ngohlobo — okushintshayo yindlela ukuvalwa kukagesi okuhlelwa ngayo.

• Isakhiwo se-bay, izikhala ze-phase nezengxenye, kanye nomthwalo wesakhiwo
• Uhlelo lwe-busbar — olulodwa, oluyinhloko nolwedlulisayo, noma olunama-bus amabili — lukhethwa ngokomsebenzi, hhayi ngomkhuba
• Izinhlelo zokuvikela, zokukala nezokulawula, nezilungiselelo zama-relay ezikhishwa njengeshejuli
• I-earth mat eklanywe kusukela ku-soil resistivity ekaliwe, kuhlolwe i-step ne-touch potential
• Ukumiswa ne-pre-commissioning kwama-isolator, ama-breaker, ama-CT, ama-PT, ama-CVT nama-lightning arrestor
• Ukufakwa kukagesi, ukuvivinywa komthwalo nokudluliselwa okubhaliwe — kuhlanganise nokwelulwa okwenziwa eyadini esasebenza ngogesi

Onjiniyela bethu bakhona endaweni yomsebenzi, kuze kufike ekufakweni kukagesi nasekudluliselweni. Lapho usunokhontileka wokumisa, thina sengamela kunalokho, okuvamise ukubiza kancane futhi kugcine amalungiselelo akho akhona njengoba enjalo. Ukuhlolwa kwenziwa ngezinsimbi zethu futhi kubikwe nezibalo ezifundiwe, hhayi nje imaki lokuphumelela.

• Ukumiswa nokufakwa kwezinhlelo ze-HT ne-LT, noma ukwengamela ukhontileka wakho
• Ukuhlolwa kwe-pre-commissioning, ukuhlolwa kwama-loop nokuhlolwa kokusebenza
• Ukuhlolwa okujwayelekile nokukhethekile kwama-transformer, kwe-switchgear, kwama-breaker nakwama-relay
• Ukuhlolwa nokulinganiswa kwama-relay okuvikela ngokwezilungiselelo ezigunyaziwe
• Ukufakwa kukagesi, ukuvivinywa komthwalo nokudluliselwa okubhaliwe
• Ama-relay ahlanganiswa ne-SCADA yakho ekhona, noma nentsha

Amaphaneli ahlala isikhathi eside kunefekthri ayeklanyelwe yona. Kunokuba sishintshe ibhokisi elisaqinile, sishintsha okugugile ngaphakathi kulo — ama-electromechanical relay sifake ama-numerical, ama-breaker asaphelelwa yisikhathi sifake afanayo atholakalayo namuhla, izintambo nezixhumo lapho kungasahambisani nomsebenzi — bese siphinda sikhiphe ama-schematic ukuze imidwebo ifane nephaneli futhi.

• Ama-electromechanical relay ashintshwa ngama-numerical, anezilungiselelo ezintsha
• Ama-breaker nama-contactor asaphelelwa yisikhathi ashintshwa ngalawo afanayo atholakalayo namuhla
• Ukufakwa kabusha kwezintambo, ukuxhumeka kabusha nokufakwa kwamalebula ngokohlelo olubuyekeziwe
• Ama-schematic ashintshiwe nocwaningo olusha lokuhlanganisa lomthwalo wanamuhla
• Kwengezwa ukuxhumana ukuze iphaneli elidala libike ku-SCADA
• Kwenziwa ngezikhathi zokuvalwa komsebenzi, kuhlelwe ngokuvalwa kukagesi kwakho

I-odithi efanele ukuthathelwa izinyathelo isekelwe ekukalweni kunokusekelwa kwidatha yepuleti legama. Siqopha umthwalo, sikale i-power factor nama-harmonic lapho kubalulekile, senze i-thermography kumaxhumo ashisayo ngempela, futhi sibike ukuthi ushintsho lungonga malini uma kuqhathaniswa nokuthi lubiza malini. Ukuhlolwa kwesimo sama-transformer nese-switchgear kubikwa ngendlela efanayo.

• Ukuqoshwa komthwalo, ukukalwa kwe-power factor nokwama-harmonic
• I-thermography yamaxhumo, yezixhumo neye-switchgear ngaphansi komthwalo
• Ukuhlolwa kwesimo se-transformer: tan-delta, SFRA, i-partial discharge, ukuhlungwa kwamafutha
• Ukuhlolwa kwe-soil resistivity nokukalwa kwe-earth resistance
• Imibiko yokwenzeka enezincomo ezinezindleko
• Ukuhlinzekwa kwezingxenye zokushintsha zikagesi
