Kodi mphamvu ya rotor ya hydro-generator imachokera kuti?

Mphamvu ya hydropower ndi matenthedwe onse ayenera kukhala ndi chosangalatsa. The exciter nthawi zambiri amalumikizidwa ku shaft yayikulu yofanana ndi jenereta. Pamene shaft yaikulu imazungulira pansi pa galimoto ya prime mover, nthawi imodzi imayendetsa jenereta ndi exciter kuti izungulira. The exciter ndi DC jenereta kuti zimatulutsa DC mphamvu, amene amatumizidwa kwa koyilo ya rotor kudzera mphete kutsetsereka wa rotor wa jenereta kupanga maginito mu rotor, potero kupanga mphamvu ananyengerera mu stator wa jenereta. The exciter wa lalikulu jenereta akonzedwa m'malo ndi kudziletsa shunt AC dongosolo madyerero, ambiri amene ntchito voteji wa kubwereketsa jenereta podutsa kusintha kosangalatsa, kudutsa chipangizo rectifier mu mwachindunji panopa, ndiyeno kutumiza panopa kudzera jenereta rotor kuzembera mphete. ku rotor ya jenereta. Dongosolo lamtunduwu likagwiritsidwa ntchito, kusangalatsa koyambirira kwa jenereta kuyenera kuchitika nthawi iliyonse ikayatsidwa, ndikowonjezera chisangalalo choyambirira ku jenereta kuti akhazikitse voteji yoyamba ya jenereta.

Chisangalalo cha exciter yachikale imadalira remanence yake yokha, yomwe ingapangitse exciter kupanga magetsi, koma mphamvu ndi yaying'ono kwambiri ndipo voteji ndi yofooka kwambiri, koma panopa ofooka amadutsa koyilo yosangalatsa ya exciter kulimbikitsa remanence. zotsatira. Izi zolimbitsa maginito akupitiriza kupanga exciter kupanga magetsi, amene ali mphamvu kwambiri kuposa otsalira maginito mphamvu m'badwo, ndiyeno kubwereza izi mobwerezabwereza, voteji otulutsidwa ndi exciter akhoza kukhala apamwamba ndi apamwamba, ndiko kunena kuti, magetsi otulutsidwa ndi exciter ndi yoyamba yokha. Amagwiritsidwa ntchito kukhazikitsa luso lake, ndipo amangopereka chisangalalo cha jenereta pamene magetsi ena apamwamba afika. Dongosolo lachisangalalo la ma seti amakono akuluakulu a jenereta amatengera makina osangalatsa a microcomputer, ndipo chisangalalo chake choyambirira chimaperekedwa ndi magetsi oyambira, omwe amaperekedwa ndi gridi yamagetsi kapena ndi magetsi a DC amagetsi.
