Ngwa jenera hydroelectric bụ ngwaọrụ mgbanwe ike nke na-agbanwe ike mmiri ka ọ bụrụ ike eletrik. Ọ na-abụkarị turbine mmiri, jenera, governor, sistemu mkpali, sistemu oyi na ngwa njikwa ọdụ ọkụ.
(1) Turbine hydraulic: e nwere ụdị turbine hydraulic abụọ a na-ejikarị eme ihe: ụdị mkpali na ụdị mmeghachi omume.
(2) Generator: ọtụtụ jenerato bụ jenerato synchronous, nwere obere ọsọ, na-adịkarị n'okpuru 750r/min, ụfọdụ nwekwara naanị ọtụtụ mgbanwe/minto; N'ihi obere ọsọ, enwere ọtụtụ ogidi magnetik; Nnukwu nha na ibu nhazi; Enwere ụdị ntinye abụọ nke nkeji jenerato hydraulic: kwụ ọtọ na kwụ ọtọ.
(3) Ngwa njikwa ọsọ na njikwa (gụnyere ngwa njikwa ọsọ na ngwaọrụ nrụgide mmanụ): ọrụ nke onye na-achịkwa ọsọ bụ ịhazi ọsọ nke turbine hydraulic, iji hụ na ugboro ole ike eletrik na-apụta na-emezu ihe achọrọ maka ọkọnọ ike, yana iji nweta ọrụ nkeji (mmalite, mmechi, mgbanwe ọsọ, mmụba ibu na mbelata ibu) yana ọrụ nchekwa na akụ na ụba. Ya mere, arụmọrụ nke onye na-achịkwa ga-emezu ihe achọrọ maka ọrụ ngwa ngwa, nzaghachi dị nro, nkwụsi ike ngwa ngwa, ọrụ na mmezi dị mfe, ọ chọkwara ọrụ aka a pụrụ ịdabere na ya na ngwaọrụ mmechi mberede.
(4) Sistemụ mkpali: ihe na-emepụta hydraulic bụkarị ihe na-emepụta electromagnetic synchronous. Site na njikwa nke sistemụ mkpali DC, enwere ike nweta nhazi voltaji nke ike eletrik, nhazi nke ike na-arụ ọrụ na ike mmeghachi omume na njikwa ndị ọzọ iji melite ogo ike eletrik mmepụta.
(5) Sistemụ oyi: a na-ejikarị obere jenerato hydraulic eme ka elu stator, rotor na ígwè dị n'ime jenerato ahụ jụọ oyi site na sistemụ ikuku. Agbanyeghị, ka ikike otu nkeji na-abawanye, ibu okpomọkụ nke stator na rotor na-abawanye mgbe niile. Iji mee ka ike mmepụta kwa nkeji nke jenerato ahụ dịkwuo elu na ọsọ ụfọdụ, jenerato hydraulic nwere ikike buru ibu na-anabata ụdị mmiri oyi kpọmkwem nke windings stator na rotor; Ma ọ bụ mmiri na-eme ka winding stator dị jụụ, ebe ifufe siri ike na-eme ka rotor dị jụụ.
(6) Ngwa njikwa ọdụ ike: akụrụngwa njikwa ọdụ ike dabere na obere kọmputa, nke na-arụ ọrụ nke njikọ grid, nhazi voltaji, mgbanwe ugboro ugboro, nhazi ihe ike, nchekwa na nkwukọrịta nke jenereta hydraulic.
(7) Ngwaọrụ brek: ihe nrụpụta hydraulic niile nwere ikike karịrị otu uru nwere ngwaọrụ brek, nke a na-eji brekị rotor mgbe niile mgbe a na-ebelata ọsọ ahụ ruo 30% ~ 40% nke ọsọ enyere n'oge mmechi jenereta, ka o wee gbochie ihe nrụpụta ahụ ịgba ọkụ n'ihi mmebi ihe nkiri mmanụ na obere ọsọ. Ọrụ ọzọ nke ngwaọrụ brek bụ iji mmanụ nrụgide dị elu mechie akụkụ ndị na-agbagharị nke jenereta ahụ tupu etinye, ndozi na mmalite. Ngwaọrụ brek na-eji ikuku emechiri emechi maka brek.
