Gịnị ka Generator Los-of-Excitation Nchekwa Pụtara? (Nkebi nke 1)

Okwu Mmalite nke Nchekwa Ọnwụ-nke-akpalite Generator mfu-of-excitation nchedo bụ ụdị nchebe mgbanaka ọkụ. Ọ na-ezo aka na mwepu na mberede ma ọ bụ akụkụ akụkụ nke mkpali generator. Mgbe igwe na-ere ọkụ na-atụfu kpamkpam mkpali, ihe dị ugbu a na-akpali akpali ga-eji nwayọọ nwayọọ na-emebi ruo efu. Mgbe uru δ gafere oke nkwụsi ike kwụ ọtọ, onye na-emepụta ọkụ na-efunahụ mmekọrịta ya na sistemụ ike. N'oge a, ngwaọrụ nchebe nke generator na-arụ ọrụ na onye na-emepụta ihe na-emepụta ihe na-emepụta ihe na-emepụta ihe na-eme ka onye na-emepụta ihe na-eme ka ọ ghara ịdị na-eme ka onye na-emepụta ihe na-emepụta ihe na-eme ka ọ ghara imebi ihe na-eme ka ọ dị ike. A na-akpọ ụdị nchebe a nchebe ọnwụ-nke-akpalite.

N'ozuzu, a na-eji relay voltaji dị ka ihe mmechi na sekit rotor, a na-edobekwa impedance dị ka okirikiri dị oke egwu dị ka ihe ndabere maka ime ihe. Nkọwa nke impedance na ọdụ generator bụ isi ihe ndabere maka nchekwa ọkụ ọkụ ọkụ ọkụ. Mgbe a na-ezute ma ihe nkwụsi ike nke static na obere rotor voltaji criterion, ọ pụtara na generator enwekwaghị mmasị na nkwụsi ike. Ngwá ọrụ nchebe generator ga-ezipụ ngwa ngwa mgbaama enweghị ntụkwasị obi, a ga-ewepụkwa igwe na-emepụta ihe mgbe oge nkwụsịtụ setịpụrụ.

Enwere ike iji nkwụsi ike kwụ ọtọ naanị iji mebie generator. Mgbe obere voltaji rotor gafere uru nchedo setịpụrụ, ngwaọrụ nchebe ga-ezipụ mgbama mfu nke mkpali. Mgbe ọ gafere oke nke ngwaọrụ nchekwa, ngwaọrụ nchekwa generator ga-ebipụ mmejọ ahụ ozugbo. Usoro a nwere ike ibu amụma ma generator ọ ga-efunahụ nkwụsi ike n'ihi nkwụsị nke mkpali, nke mere na enwere ike ịme usoro ntuziaka n'oge tupu generator efunahụ nkwụsi ike iji gbochie ihe mberede ahụ ịgbasa.

Nchekwa mfu nke mkpali na-anabata ọrụ asynchronous kpatara site na mmejọ dị na sekit excitation generator ma na-eji okirikiri asynchronous impedance.

Usoro ihe omume bụ:

Ebe: U1 na I1 bụ voltaji dị mma na nke ugbu a n'otu n'otu, UN bụ voltaji e gosiri nke generator (57.7V), ie bụ nke abụọ gosiri ugbu a nke generator, Xd bụ uru otu unit nke generator synchronous reactance, na X'd bụ kwa unit uru nke generator transient reactance.

Maka ntụkwasị obi, a na-agbakwunye ụkpụrụ inyeaka: U2 <0.1UN, ebe UN bụ voltaji nke ọkụ ọkụ (57.7V).

Nchedo ahụ ga-adaba naanị mgbe emezuru ụkpụrụ abụọ ahụ. Edobere nchekwa ahụ na oke oge abụọ, nke enwere ike ịtọ ya iche. N'ozuzu, a na-eji njedebe oge mbụ iji belata mmepụta ike ma gbanwee gaa na nkwado ndabere, na njedebe nke abụọ ka a na-eji gbanyụọ generator ma kpochapụ oghere magnet.
