Pane mutoro bvunzo yehydro generator unit

1. Kudzikira uye kuyedzwa kwekuremerwa kwemahydro generator unit kuchaitwa zvakachinjana. Mushure mekunge chikwata chatanga kutakurwa, kushanda kweyuniti uye yakakodzera electromechanical michina inofanira kuongororwa. Kana pasina kukanganiswa, bvunzo yekuramba mutoro inogona kuitwa zvinoenderana nemamiriro ehurongwa.

2. Munguva yekuedzwa kwemutoro weiyo mvura turbine generator unit, mutoro unoshanda uchawedzerwa nhanho nhanho, uye kushanda kwechikamu chimwe nechimwe chechikwata uye chiratidzo chechiridzwa chimwe nechimwe chichacherechedzwa uye kunyorwa. Tarisa uye kuyera iyo vibration renji uye ukuru hweiyo unit pasi pemamiriro akasiyana-siyana ekuremerwa, kuyera kukosha kwekumanikidza kweiyo dhizaini chubhu, tarisa mamiriro ekushanda emvura inotungamira mudziyo weiyo hydraulic turbine, uye ita bvunzo kana zvichidikanwa.

3. Ita iyo yekumhanyisa regulation system bvunzo yeyuniti iri pasi pemutoro. Tarisa kugadzikana kweiyo unit regulation uye mutual switching process pasi pekumhanya uye simba rekudzora maitiro. Kune propeller turbine, tarisa kana hukama hwehukama hwekukurumidza regulation system hwakarurama.

4. Ita kukurumidza kuwedzera mutoro uye kuderedza bvunzo yeyuniti. Zvinoenderana nemamiriro enzvimbo, kuerekana kwakaremerwa kweyuniti hakuzoshanduke kupfuura iyo yakayerwa mutoro, uye shanduko yekuchinja kweiyo unit kumhanya, volute mvura kudzvanywa, dhizaini chubhu pressure pulsation, servomotor sitiroko uye shanduko yemagetsi ichanyorwa otomatiki. Mukuita kwekuwedzera kwemutoro, teerera kutarisa uye kutarisa vibration yeyuniti, uye rekodha inowirirana mutoro, unit musoro uye mamwe ma parameter. Kana iyo unit iine kudengenyeka kuri pachena pasi pemusoro wemvura wazvino, ichayambuka nekukurumidza.

5. Kuitisa excitation regulator bvunzo yehydro generator unit pasi pemutoro:
1) Kana zvichibvira, gadzirisa simba rekuita rejenareta kubva ku zero kusvika kuhuwandu hwehuwandu hunoenderana nezvinodiwa zvekugadzira apo simba rinoshanda rejenereta riri 0%, 50% uye 100% yehuwandu hwehuwandu hunoenderana, uye kugadzirisa kuchave kwakagadzikana uye pasina kupera.
2) Kana zvichibvira, kuyera uye kuverenga iyo terminal voltage regulation rate ye hydro jenareta, uye hunhu hwekutonga huchava nemutsara wakanaka uye kusangana nezvinodiwa zvekugadzira.
3) Kana zvichibvira, pima uye kuverenga iyo static pressure musiyano weiyo hydro jenareta, uye kukosha kwayo kunosangana nezvinodiwa zvekugadzira.Kana pasina dhizaini mirau, haifanire kuve yakakura kupfuura 0.2%, -, 1% yemhando yemagetsi uye 1%, - 3% yemhando yemagetsi.
4) Kune iyo thyristor excitation regulator, dzakasiyana-siyana limiter uye dziviriro bvunzo uye zvigadziriso zvichaitwa zvichiteerana.
5) Kumayuniti akashongedzerwa nemagetsi system kugadzikana system (PSS), 10% - 15% yakatarwa mutoro ichachinjwa kamwe kamwe, zvikasadaro basa rayo richakanganiswa.
6. Paunenge uchigadzirisa mutoro unoshanda uye unogadzirisa mutoro wechikwata, uchaitwa kune gavhuna wemunharaunda uye chigadziro chekusimudzira maererano, uye zvino kudzora uye kugadziriswa kuburikidza nekombiyuta yekudzora system.
