Mahi tahi o nga Kaihanga

Ko te tiaki hiko whakamuri ka kiia hoki ko te tiaki huarahi hiko.Ko te tikanga, ko te aronga mana o te kaihanga Me waiho te ahunga o te kaihurihuri ki te pahi, engari ka ngaro te aukumetanga o te kaihurihuri, i etahi atu take whakangao ranei, ka huri pea te kaihanga ki te mahi motini, ara, ka toia te mana kaha mai i te punaha.Koinei te mana kōaro.Ka tae te mana kōaro ki tetahi uara, ko te mahi tiaki a te kaihanga, he mahi ranei hei tohu, hei mahi ranei ki te haere.

Ko te turbogenerator hono-matiti e mahi ana hei motini tukutahi i muri i te katinga o te pihanga matua o te turbine: ka mimiti i te mana kaha, ka toia te huri hiko, ka taea te tuku i te mana reactive ki te punaha.Na te mea kua katia te maataki matua o te kapohau mamaoa, ka taupatupatu te mata hiku o te kapohau mamaoa me te toenga o te mamaoa ka puta te mate o te pupuhi, ka pakaru i te wera nui i te wa roa e mahi ana.Ko te hau me te kapohiko wai he morearea nui ki nga kaikawe tuatahi.Kaihanga whakamuri te tiaki hiko matua tiaki mamaoa turbine mai i te kino.

Ko te tautuhi i te tatauranga mo te tiaki hiko hurihuri mamaoa ko te whakatau i te mana whakahaere Pdz me te whakaroa mahi T o te tiaki.

1. Ka taea te tatau i te mana mahi o te Pdz set turbogenerator inverse power maintenance action power to the following formula: Pdz=(Krel*P1)/η Pdz- Inverse power maintenance operation power Krel- reliability coefficient, tango 0.8 P1- te mana pau na te turbine ki te pupuri i te tere hurihanga tukutahi i muri i te kati o te paera matua, ko te rahi o tenei mana e pa ana ki te hanganga turbine me te kaha, E pa ana ano ki te hanganga o te punaha mamaoa matua o te turbogenerator (te hanganga paipa me te mea kei te haerehia. paipa, me ētahi atu), te tikanga tango 1.5~2% o te mana whakatau η- te kakama ka toia te generator te turbogenerator ki te takahuri, tango 0.98~0.99 na: Pdz≈ (1.2~1.6%) PN PN- te mana whakatau o te kaihanga.I roto i te mahi, Pdz= ka taea te 1-1.5% PN.

2. mahi whakaroa generator kōaro te mana tiaki mahi whakaroa, kia i roto i runga i te generator mamaoa turbine i muri i te vaolo matua katia whakaaetia ki te mahi wa ki te whakaturia, te wa whakaaetia ko te tikanga 10 ~ 15min.E whakaatu ana te tatauranga me nga mahi whakahaere ina he paipa haere te punaha mamaoa turbine mamaoa, ka roa ake te waa mahi e whakaaetia ana.Na reira, ki te whakaritea te whakaroa mahi tiaki i runga i te wa e whakaaetia ana ki te rere i muri i te katinga o te kaitapa hiko mamaoa matua, 5 ~ 10min he mea tika.I muri i te mahi, ka whakamahia ki te whakakore i te papa autō.

I tua atu, ko nga turbogenerators nui e mahi ana i te nuinga o te waa e whakamahi ana i te tiaki hiko whakamuri hei tiimata i te kaupapa haerenga haerenga.I tenei wa, ko te waa mahi ko te tikanga 1~2s.Mo te tiaki i te mana hurihuri e whakahaeretia ana e te kaupapa, na te poto o te mahi, ka iti pea te mana hurihuri mahi i roto i te wa poto i muri i te katinga o te ira takirere mamaoa matua na te koretake o te turbine me te kaihanga, na reira. kia kaua e nui ake te uara pumau o te mana kōaro i te 1%PN.

Ina he mana whakamuri te kaitahuri (te tohu hiko o waho ki te miihini, ara, ka huri te miihini ki te ahua motini), ko te hiko whakamuri te mahi tiaki ara iahiko haerenga.E toru nga wahanga ngaohiko me nga tohu o naianei e rua me kohia.Na te rereke o nga ahuatanga o te kaha tuatahi, ka taea te hanga i nga momo miihini rereke.Ma te mahi tahi o nga rawa wai me te kapohau wai, ka taea te hanga he wai whakangao.Na te rereke o te kaha o te puna me te mahunga o te mahunga, ka taea te hanga hydrogenerators he rereke te kaha me te tere.Ma te whakamahi i te waro, te hinu me etahi atu rauemi, me te kohu, te turbine me te miihini mamaoa, ka taea te hanga i te miihini hiko, ko te nuinga o te motuka tere (3000rpm).I tua atu, he maha nga momo miihini e whakamahi ana i te ra, te hau, te ngota, te waiariki, te tai, te koiora me etahi atu hiko.I tua atu, no te mea he rereke te kaupapa mahi o te kaihanga, ka taea te wehea ki te DC generator, generator asynchronous me te generator tukutahi.Ko nga kaihanga nui e whakamahia whanuitia ana ko nga kaihanga tukutahi.

Kei a Dingbo nga momo miihini hiko mohoao: Volvo / Weichai /Shangcai/Ricardo/Perkins me etahi atu, mena ka hiahia koe ki te whakapiri mai ki a maatau
