Hoʻolauna i ke kumu o nā mea hana Diesel

Ma hope o ka pani ʻia ʻana o ka pahu nui o ka turbine, e hana ana ka turbogenerator pili i ka grid ma ke ʻano he motika synchronous, e hoʻomoʻi i ka mana ikaika a kauo i ka turbine e hoʻohuli, a laila e hoʻoulu ai i ka mana reactive no ka ʻōnaehana.No ka mea, ua pani ʻia ka pahu nui o ka turbine mahu, ua pani ʻia ka huelo turbine turbine a me ke koena o ka mokuahi friction, e hana ana i ka pōʻino pahū, overheating pōʻino ma hope o ka hana lōʻihi.Ke kinoea a me ka wai turbines kekahi e poino nui i ka prime mover. Mea hana hana ʻO ka hoʻihoʻi ʻana i ka mana e pale nui i ka turbine mai ka pōʻino.

ʻO ka hoʻonohonoho ʻana o ka turbine inverse power protection e hoʻoholo i ka mana hana pale Pdz a me ka hoʻopaneʻe hana T.

1、ʻO ka mana hana o ka pale ʻana i ka mana o ka turbogenerator hiki ke helu ʻia penei: Pdz = (krel * P1) / ηPdz- ka mana hana o ka reverse power protection krel- reliability coefficient, lawe 0.8 P1- ka mana i hoʻopau ʻia e ka turbine e mālama i ka wikiwiki synchronous ma hope o ka pani ʻana o ka pahu nui, pili ia i ke ʻano a me ka hiki o ka turbine mahu.E pili pū ana i ke ʻano o ka ʻōnaehana mahu nui o ka turbine generator (pipeline structure a inā aia nā paipu bypass, etc.).Ma lalo o nā kūlana maʻamau, ʻo ka mana helu η o 1.5 ~ 2% (ka maikaʻi i ka wā e hoʻokele ai ka mea hana i ka turbine generator e hoʻololi) ʻo 0.98 ~ 0.99, no laila: PDZ∑(1.2 ~ 1.6%) PN - ka mana helu o ka mīkini hana.ʻOiaʻiʻo, ʻoi aku ka maikaʻi o Pdz = 1-1.5% PN.

2、 Hoʻopaneʻe ka hana . Pono e hoʻonohonoho ʻia ka lohi hana o ka generator inverse power protection e like me ka manawa holo i ʻae ʻia o ka panina kiwi nui o ka turbine generator.ʻO ka manawa i ʻae ʻia he 10 ~ 15 mau minuke.Hōʻike ka helu ʻana a me ka hana hana i ka wā i loaʻa ai i ka ʻōnaehana turbine mahu ka paipu, ʻoi aku ka lōʻihi o ka manawa holo.No laila, inā hoʻonohonoho ʻia ka lohi o ka pale e like me ka manawa holo i ʻae ʻia ma hope o ka pani ʻana o ka pahu nui o ka turbine mahu, hiki ke lawe ʻia nā minuke 5 ~ 10.Ma hope o ka hana, hoʻohana ʻia i ka demagnetization.

Eia kekahi, ʻo ka hapa nui o nā turbogenerators i ka hana e hoʻohana i ka pale o ka mana hoʻohuli e hoʻomaka i nā kaʻa huakaʻi i hoʻonohonoho ʻia.I kēia manawa, lawe pinepine ka manawa hana i 1 a 2 mau hola.No ka pale ʻana i ka mana inverse i hoʻolālā ʻia, ma muli o ka manawa hana pōkole, hiki ke liʻiliʻi ka mana inverse maoli ma muli o ka inertia o ka turbine mahu a me ka generator i loko o kahi manawa pōkole ma hope o ka pani ʻana o ka pahu nui, no laila pono ka waiwai paʻa o ka mana inverse. ʻaʻole ʻoi aku ma mua o 1%PN.

Mea hana mīkini hana hoʻolauna kumu

Ke loaʻa ka mana hoʻohuli i ka mīkini hana (ke kuhi ka mana o waho i ka mīkini hana, ʻo ia hoʻi, lilo ka mīkini hana i ka moto), pale ka mana hoʻohuli i ka mea haʻihaʻi kaapuni hana mai ka hele ʻana.Pono e hōʻiliʻili ʻia nā ʻāpana uila ʻekolu a me nā hōʻailona o kēia manawa.

Ma muli o nā ʻano like ʻole o ka ikehu mua, hiki ke hana ʻia nā mea hana like ʻole.Hiki ke hana ʻia nā hydrogenerators mai ka wai a me nā turbines.Ma muli o ka mana o ka waihona a me ka hāʻule, hiki ke hana ʻia nā hydro-generators me nā mana like ʻole a me ka wikiwiki.Ma ka hoʻohana ʻana i ka lanahu, ka aila a me nā kumuwaiwai ʻē aʻe, me nā pahu pahu a me nā ʻenekini turbo-steam, hiki ke hana ʻia nā mea hoʻoheheʻe turbine mahu, ʻo ka hapa nui o nā kaʻa holo wikiwiki (3000rpm).Aia kekahi mau mea hana e hoʻohana ana i ka lā, makani, atomic, geothermal, tidal a me bioenergy.Eia kekahi, ma muli o nā loina hana like ʻole o nā mea hana, ua māhele ʻia lākou i DC generators, asynchronous generators a synchronous generators.ʻO nā mea hana nui i hoʻohana nui ʻia he synchronous generators.
