Kedu ihe na-ebute mgbanwe ike na-arụ ọrụ na Generator Set

Mgbanwe ike na-arụ ọrụ nke igwe na-emepụta ihe na-enwe mmetụta dị ukwuu na nkwụsi ike nke ọrụ nke generator set.Oke nkwụsi ike nke mgbanwe ike na-arụ ọrụ nke onye na-emepụta ọkụ na-arụ ọrụ n'azụ oge dị oke.Mgbe generator na-arụ ọrụ na-eduga na-arụ ọrụ, karịsịa n'ime akụkụ miri emi nke na-eduga ọrụ, a ga-ebelata oke nkwụsi ike nke ihe nrụpụta generator, nke dị mfe ime ka generator setịpụ nkwụsi ike na njem, nke na-eyi egwu arụ ọrụ nchekwa. unit na ike okporo.

Edemede a na-enyocha ihe kpatara ngbanwe ike nke igwe na-emepụta ihe, wee were ihe mgbochi ezubere iche iji hụ na arụrụ ọrụ nke igwe na-emepụta ihe.

1. Mmetụta nke reactive ike na-arụ ọrụ ike

Nyocha banyere mmekọrịta dị n'etiti ike na-arụ ọrụ na reactive ike nke generator

The generator excitation ngwaọrụ na-enyocha na-enweghị akpaka ukpụhọde na dum usoro nke generator praịm mover ike, na onye ọrụ na-edozi naanị generator ike arụ ọrụ, nke bụ ihe kwekọrọ na-edebe generator nwere E na reactance mgbe nile.Ike na-arụ ọrụ na ike akụkụ nke generator bụ sinusoidal, na ike reactive na ike akụkụ bụ cosine.

Na usoro, E0, U bụ generator ike na ọnụ voltaji;X1 bụ synchronous reactance nke generator;δ bụ akụkụ ike eletrik nke generator.

Enwere ike ịhụ na ka ike na-arụ ọrụ na-abawanye, ka ike na-emeghachi omume na-ebelata.Mgbe ụfọdụ ike akụkụ ruru, generator na-agbanwe site na mbubreyo na-arụ ọrụ na-aga n'ihu na-adọ ọrụ, na-amịkọrọ inductive reactive ike si usoro.The ike n'akuku na-abawanye na-abawanye nke na-adọ omimi, na miri emi na-eduga na-adọ bụ, nta ka excitation ugbu a bụ.Ya mere, iji zere oke oge na-aga n'ihu nke generator, ọ dị mkpa iji mee ka ihe na-akpali akpali ugbu a ka ọ na-abawanye ike na-arụ ọrụ nke onye na-emepụta ihe, iji belata ọganihu dị elu ma hụ na voltaji njedebe na-adịgide adịgide.

2.Influence nke unit ugboro ụkpụrụ, regulating ogbo mgbali na isi ugboro ụkpụrụ na-arụsi ọrụ ike ike.

1) Nrụgide nke usoro nhazi nke unit ahụ dị n'otu ọnọdụ dị ka mgbanwe nke ike na-arụ ọrụ.N'ime oge okirikiri, nrụgide nke usoro nhazi nke unit bụ nkeji 20 tupu mgbanwe nke ike na-arụ ọrụ.

2) Ugboro nkeji na-aga n'ihu na mgbanwe ike na-arụ ọrụ, yana mgbanwe nkeji nkeji bụ 0.1s n'ihu mgbanwe ike na-arụ ọrụ na okirikiri oge.

3) Mgbanwe ike na-arụ ọrụ nke unit na-akpata site na usoro iwu ugboro ugboro.Na ụkpụrụ, usoro iwu ugboro ugboro na-arụ ọrụ site na ọsọ nke generator.

Enwere ike nyochaa na mgbanwe nke mmalite ọsọ generator na-ebute usoro iwu ugboro ugboro.Nsonaazụ nke isi ugboro ụkpụrụ omume iwu na-egosipụta na mgbanwe nke unit ụkpụrụ ogbo mgbali, na mgbe ahụ na-egosipụta na mgbanwe nke unit ugboro na ike nọ n'ọrụ.

3.Influence nke grid ugboro na-arụ ọrụ ike

Enwere ike ịhụ site na eserese nke waveform na njupụta ngbanwe ugboro ole nke grid ike dị ntakịrị karịa nke igwe na-emepụta ọkụ, na oge oge adịghị njọ na ọ fọrọ nke nta ka ọ bụrụ oge.Ya mere, enwere ike iwepụ mmetụta nke ugboro grid na ngbanwe ike na-arụ ọrụ.

Site na nyocha nke dị n'elu, enwere ike iwepụ mmetụta nke ike na-emeghachi omume, usoro nchịkwa mkpali, ugboro netwọk na ihe ndị ọzọ na mgbanwe ike na-arụ ọrụ.A na-ekwubi na mgbanwe ike na-arụ ọrụ nke generator set na osisi bụ n'ihi na mmụba nke generator set ọsọ, isi ugboro iwu na-eme ihe, n'otu oge ahụ, n'ihi na oghere nke elu-ọsọ regulating valvụ nke uzuoku turbine bụ na inflection ebe, e ji mara curve na inflection. isi bụ nnọọ ejighị n'aka.Mgbe usoro iwu ugboro mbụ na-arụ ọrụ, iwu mmeghe natara site na valvụ na-achịkwa na mpaghara a dị na steeti izipu.

4.Mgbochi na mgbochi

Ntọala generator dị na njedebe nke grid ike, yana ogologo eriri eriri abụọ na-apụ apụ na ebe nkwado ike dị mkpa.N'ihi na ugbu a Mbelata nke ulo oru ike oriri, reactive ike jubigara ókè nke ike okporo na elu usoro voltaji, iji hụ na voltaji àgwà, ike grid ga-achọ unit na-arụ ọrụ na-adọ, na otu igwe ọrụ nwere oke. ike banye reactive ike na mezie voltaji usoro.Na mgbakwunye na mgbanwe ike na-arụ ọrụ nke unit ahụ, a na-emepụta usoro mgbochi ndị a:

(1) Ọnọdụ ọrụ dị ugbu a nwere mmetụta dị ukwuu na nkwụsi ike nke unit ahụ.Maka nnukwu usoro grid ike, arụ ọrụ nhazi nke generator set nwere oke.Ya mere, a na-achọrọ na ikike nke isi nke otu ahụ kwesịrị ekwesị mgbe voltaji sistemu dị oke elu, a ga-ezerekwa ọrụ na-eduga miri emi dị ka o kwere mee.

(2) N'ihi usoro iwu na-adịghị ahụkebe nke valvụ na-achịkwa ọsọ ọsọ, enwere ebe mgbaba ihe dị ka 70% nke ọnọdụ valvụ zuru oke.N'oge a, ọ bụrụ na akụkụ dị iche iche nke usoro nchịkwa na-agbanwe (gụnyere usoro mgbanwe nke mbụ), enwere ike ime mgbanwe nchịkwa n'oge a, nke nwere ike ime ka mgbanwe dị ukwuu na oghere nke valvụ na-achịkwa ma na-eduga n'ịgbanwe mgbanwe. ike na-arụ ọrụ.N'ihi ọnọdụ a, ihe dị ugbu a bụ iji zere nkwụsịtụ nke valvụ na-achịkwa.
