Pane mutoro bvunzo yehydro generator unit

1. Kudzikira uye kuyedzwa kwekuremerwa kwemahydro generator units kuchaitwa zvakachinjana.Mushure mekunge chikwata chatanga kutakurwa, kushanda kweyuniti uye yakakodzera electromechanical michina ichaongororwa.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 yakatemerwa mutoro, uye shanduko yekuchinja kweyuniti 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 vibration iri pachena pasi pemusoro wemvura iripo, ichayambuka nekukurumidza.

5. Kuitisa excitation regulator bvunzo yehydro generator unit pasi pemutoro:
1) Kana zvichibvira, gadzirisa simba rekuita rejenareta kubva ku zero kusvika kune yakatemerwa kukosha zvinoenderana nezvinodiwa nedhizaini apo simba rinoshanda rejenareta riri 0%, 50% uye 100% yemutengo wakayerwa zvichiteerana, uye gadziriso ichave. yakagadzikana uye isina kupera.
2) Kana zvichibvira, kuyera uye kuverenga iyo terminal voltage regulation mwero wehydro jenareta, uye hunhu hwekutonga huchava nemutsara wakanaka uye kusangana nezvinodiwa zvekugadzira.
3) Kana zvichibvira, kuyera uye kuverenga static pressure musiyano wehuwandu hwe hydro generator, uye kukosha kwayo kunosangana nezvinodiwa zvekugadzira.Kana pasina mitemo yekugadzira, haifaniri kunge yakakura kudarika 0.2%, -, 1% yemhando yemagetsi uye 1%, - 3% yemhando yemagetsi
4) Kune iyo thyristor excitation regulator, akasiyana emiter uye yekudzivirira bvunzo uye zvigadziriso zvichaitwa zvichiteerana.
5) Kumayuniti ane simba system kugadzikana system (PSS), 10% - 15% yakatarwa mutoro ichachinjwa kamwe kamwe, kana zvisina kudaro basa rayo richakanganiswa.
6. Paunenge uchigadzirisa mutoro unoshanda uye unogadzirisa mutoro wechikwata, uchaitwa kune gavhuna wepanzvimbo uye chigadziro chekusimudzira maererano, uye zvino kudzora uye kugadziriswa kuburikidza nekombiyuta yekudzora system.
