He aha nā pōmaikaʻi o ka pale ʻana o Silent Diesel Generator Sets

Genset hāmau hiki ke hoʻemi i ka walaʻau a kaulana loa i nā hale noho, nā halemai a me nā wahi ʻē aʻe.I nā makahiki i hala iho nei, ua lilo ka mākeke no nā mea hoʻoheheʻe diesel silent.E nānā kāua i nā mea hoʻoheheʻe diesel leo ma lalo.ʻumi pono palekana.

1. Silent diesel generator poho-o-excitation pale.

Hoʻohana ʻia ka pale nalo-o-excitation ma ke ʻano he pale hewa-o-excitation i ka wā e hāʻule ʻole ai ke ʻano o ka hoʻoulu ʻana o ka mea hana hana.Hoʻokumu ʻia ia me nā pae hoʻohālikelike e like me ka excitation haʻahaʻa uila Ufd (P), ʻōnaehana haʻahaʻa haʻahaʻa, static stability impedance, TV disconnection nona ka hoʻonohonoho ʻana i ka waiwai e hoʻololi maʻalahi me ka mana ikaika, e hana ana i ka hōʻailona a me ka de-excitation.ʻO ka excitation haʻahaʻa haʻahaʻa Ufd(P) criterion a me ka static stability impedance criterion e pili ana i ka palena static stability, hiki ke ʻike inā nalowale ka mea hana i kona kūpaʻa static ma muli o ka nalowale o ka excitation.Ke hana nei ka static stability impedance criterion ma ka palena static stability ma hope o ka nalowale o ka magnetism.

2. Mute diesel generator overexcitation pale.

ʻO ka pale o ka overexcitation kahi pale e hōʻike ana i ka nui o ka hana maʻemaʻe magnetic o ke kumu hao ma muli o ka hōʻemi pinepine ʻana o ka mīkini hana a i ʻole ka nui o ka uila.Hoʻokaʻawale ʻia ka pale overexcitation i nā hoʻonohonoho kiʻekiʻe a haʻahaʻa.Hoʻouna ka haʻahaʻa haʻahaʻa i kahi hōʻailona ma hope o ka lohi paʻa o 5s a hoʻemi i ka voli excitation (ʻo ka hana o ka hoʻohaʻahaʻa ʻana i ka volter excitation a me ka hoʻoulu ʻana i kēia manawa ʻaʻole i hoʻohana ʻia), a ke hana nei ka hoʻonohonoho kiʻekiʻe i ka de-loading ma hope o ka palena manawa inverse.Demagnetization.ʻO ka palena kiʻekiʻe o ka hoʻopaneʻe manawa inverse he 5 kekona, a ʻo ka palena haʻahaʻa he 200 kekona.

3. Silent diesel mīkini hana hoʻoheheʻe stator pale lepo.

Hoʻohana ʻia ʻo Generator stator grounding protection e like me ka generator stator one-phase grounding fault protection.He ʻelua ʻāpana ia: ʻo ka ʻāpana ʻāpana uila zero sequence a me ke kolu o ka volta harmonic.ʻO ka puʻupuʻu kumu zero sequence e pale ai i ka wili ʻana o ka stator ma kahi 95% mai ka hopena mīkini a i ka huelo mīkini.Hoʻokumu ʻia ka hewa kumu i ka noʻonoʻo ʻana i ke kumumanaʻo o ka uila zero-sequence ma ka hopena generator, e hana ana i ka demagnetization ma hope o ka palena manawa o t1 (3s);ʻO ke kolu o ka volta harmonic e pale i ka hewa kumu hoʻokahi o ka stator wili mai ka huelo generator a hiki i 30% o ka hopena generator.Hoʻokumu ʻia ka helu kūʻokoʻa o ka mīkini hana a me ke kolu-harmonic kumu ma ka hopena generator, a hana ma ka hōʻailona ma hope o ka palena manawa o t2 (5s).ʻO nā mea ʻelua he 100% ka pale kahua stator.Ua lako ka pale me ka PT disconnection loka.

4. Silent diesel generator stator huli pale.

Hoʻokumu ʻia ka pale ʻana i ka volit sequence longitudinal zero a me ka hōʻailona kuhikuhi ʻino o ka ʻāpana hewa.Hoʻonohonoho ʻia nā ana hoʻokaʻawale ʻana o ka PT ma ke ʻano he pale nui no ka huli ʻana o loko o ka mīkini hana a me ke kaapuni pōkole a me ka welding wehe o ka wili stator.Hoʻoholo ʻia ka hōʻailona hōʻano maikaʻi ʻole o ka ʻāpana hewa Ka ʻike ʻana i ka mana ʻino-sequence e kahe ana mai loko mai o ka mīkini hana e ʻike ai i ka loaʻa ʻana o ka criterion voltage zero-sequence longitudinal ma ka ʻike ʻana i ka puka 3UO longitudinal e ka 3PT open delta winding nona ke kiko kū pololei. hoʻohui ʻia i ke kiko kūʻokoʻa o ka generator akā ʻaʻole i hoʻopaʻa ʻia.ʻO ka hana hoʻomalu i ka piha piha.

5. Silent diesel generator out-of-step pale.

Hoʻohana ka pale i kahi mea ʻekolu-impedance e ʻike i ka helu o nā pole sliding a hoʻoholo i kahi o ke kikowaena oscillation ma o ka hoʻololi ʻana o ka trajectory impedance.I ka hihia o ka pōkole pōkole, ʻōnaehana oscillation, ka wehe ʻana i ka uila, a me nā mea ʻē aʻe, ʻaʻole e hana hewa ka pale.Hoʻohana maʻamau ka pale ma ka hōʻailona;aia ke kikowaena oscillation i loko o ka hui generator-transformer, hoʻomaka ke kahua pale a hoʻouna aku i kahi kauoha huakaʻi ma o t1 (0.5s), e hana ana i ka de-excitation;aia ke kikowaena oscillation ma waho o ka hui generator-transformer, ka pale ʻO ka hoʻomaka ʻana o ka pauku II ua hōʻailona ʻia ma t2(2s).Hoʻolako ʻia ka mea pale me kahi mea hoʻopaʻa i kēia manawa e hōʻoia ʻaʻole ʻoi aku ka nui o ke au ma mua o ke au i hoʻohālikelike ʻia i waho o ka ʻanuʻu o ka mea haʻihaʻi kaapuni i ka wā e pio ai ke kaapuni.

6. Haʻahaʻa-frequency kumulative pale no ka leo diesel generators.

ʻO ka pale ʻana o ka hōʻiliʻili haʻahaʻa haʻahaʻa e pane i ka hopena kumulative o ka hoʻemi ʻana o ka ʻōnaehana ma ka turbine mahu.Aia ka pale i kahi relay a me ka counter counter, a ua ālai ʻia e ka hoʻopili kōkua o ka mea hoʻokaʻawale kaapuni puka (ʻo ia hoʻi, puka ka pale o ka hōʻiliʻili haʻahaʻa i ka wā e haʻalele ai ka mīkini hana), a haʻahaʻa ka ʻōnaehana kumulative. ua hoʻonohonoho ʻia ke alapine ma 47.5 Hz, i ka wā i hōʻiliʻili ʻia ai ka manawa i hōʻea i ka waiwai hoʻonohonoho o 3000 kekona, e hoʻouna ʻia ka hōʻailona ma hope o ka lohi o 30 kekona.Hiki ke nānā ʻia ka hāmeʻa i ka manawa maoli i ka wā o ka hana: ka waiwai paʻa, ka pinepine f a me ka hōʻike manawa kumulative.

7. Silent diesel generator excitation kaapuni overload pale.

Hoʻohana ʻia ka pale ʻana i ka excitation circuit no ka pale ʻana i ke kaapuni hoʻoneʻe rotor mai ka overcurrent a i ʻole overload.Hoʻohui ʻia i loko o kahi ʻano ʻekolu-phase a loaʻa i ʻelua ʻāpana: ka manawa paʻa a me ka palena manawa inverse.Hoʻonohonoho ʻia ke ʻano hana o ka ʻāpana manawa paʻa e like me ke kūlana e hiki ke hoʻihoʻi pono ʻia ma lalo o ka helu kiʻekiʻe loa o ka hana maʻamau.Ma hope o ka palena manawa t1 (5s), hana ia i ka hōʻailona a hoʻemi i ka manawa hoʻonāukiuki (ʻaʻole hoʻohana ʻia ka hana o ka hōʻemi ʻana i ka manawa hauʻoli);ʻO ke ʻano hana o ka ʻāpana manawa inverse e like me ka mea hoʻomohala Ua hoʻoholo ʻia ka mana overload o ka wili hoʻohiwahiwa, a ʻo ka hana pale i ka de-energization a me ka de-excitation.ʻO ka palena kiʻekiʻe o ka palena manawa inverse he 10 kekona.

8. One-point grounding protection for the rotor of silent diesel generator.

Hoʻohana ʻia ka generator rotor one-point grounding protection e hōʻike i ka hewa ʻāina hoʻokahi o ka kaapuni rotor generator.Hoʻohana ka pale i ke kumu hoʻololi ping-pong.Hoʻohālikelike ʻia nā kaha ʻāina maikaʻi a maikaʻi ʻole o ke kaapuni rotor, a ua helu ʻia ke kūʻē ʻana o ka honua i ka manawa maoli ma o ka hoʻonā ʻana i ʻelua mau hoʻohālikelike honua.A me ke kahua kahua.E hana ka pale i ka hōʻailona ma hope o ka lohi o 2 kekona.

9. Symmetrical overload pale no ka lewa diesel generators.

Hoʻokumu ʻia ka mea pale i ʻelua ʻāpana: ka manawa paʻa a me ka palena manawa inverse.Ke hana nei ka hapa manawa ma ka hōʻailona ma hope o ka palena manawa o 5 kekona.Hoʻoholo ʻia ka ʻano hana o ka manawa inverse e like me ka hiki o ka mea hana ke kū i ka overload o kēia manawa, a aia ka hana i ka de-loading.Hiki i ka mea pale ke hōʻike i ke kaʻina hana hoʻoulu wela o ka stator generator.

10. ʻO ka hoʻopaʻa ʻana i ka hoʻopaʻa ʻana i ke kaʻina ʻino no nā mea hoʻoheheʻe diesel leu.

Hoʻokumu ʻia ka mea pale i ʻelua ʻāpana: ka manawa paʻa a me ka palena manawa inverse.Hoʻonohonoho ʻia ka hana o kēia manawa palena manawa ma muli o ke kaʻina hana ʻino i ʻae ʻia no ka wā lōʻihi ka waiwai o kēia manawa mīkini hana hana a me ka waiwai o keia manawa e pale aku ai i ke kaulike ole o ke kaina kuinoino i keia manawa ma lalo o ka haawe nui loa.Hana ka lua ma ka hōʻailona.Hoʻoholo ʻia ka ʻano hana inverse time e like me ka hiki o ka mea hana ke kū i ke kaʻina hana ʻino, a aia ka hana i ka de-excitation a me ka de-excitation.

Inā makemake ʻoe e ʻike hou aʻe e pili ana i nā mea hana diesel, e ʻoluʻolu e kelepona ma ka leka uila dingbo@dieselgeneratortech.com.
