Ndedzipi Dziviriro Yakanakira yeSilent Diesel Jenareta Sets

Silent genset inogona kuderedza ruzha uye inonyanyozivikanwa munzvimbo dzekugara, zvipatara nedzimwe nzvimbo.Mumakore achangopfuura, musika wemajenareta edhiziri akanyarara wawedzera kudiwa.Ngatitarisei majenareta edhiziri akanyarara pazasi.Gumi kudzivirira zvakanakira.

1. Silent dizeli jenareta kurasikirwa-kwe-excitation kudzivirira.

Kurasikirwa-kwe-excitation kudzivirirwa kunoshandiswa sekurasikirwa-kwe-excitation kukanganisa kukanganisa apo mhepo yekukurudzira yejenereta inodonha zvisina kufanira kana kupera zvachose.Iyo inoumbwa nemaitiro akadai senge excitation yakaderera voltage Ufd (P), system yakaderera voltage, static kugadzikana impedance, TV disconnection iyo yekumisikidza kukosha kwayo inochinja otomatiki nesimba rinoshanda, iro rinoita kusaina uye de-excitation zvichiteerana.Ose ari maviri ekusimudzira yakaderera voltage Ufd (P) chiyero uye iyo static kugadzikana impedance chiyero ine chekuita neiyo static kugadzikana muganho, iyo inogona kuona kana jenareta inorasikirwa nekugadzikana kwayo nekuda kwekurasikirwa kwekunakidzwa.Iyo static kugadzikana Impedans criterion inoshanda pamuganho wakagadzikana mushure mekurasikirwa kwemagnetism.

2. Mute dizeli jenareta overexcitation kudzivirira.

Overexcitation dziviriro ndeye dziviriro inoratidza yakawandisa kushanda magineti density yesimbi musimboti inokonzerwa nekudzikiswa kwemajenareta kana yakawandisa voltage.Iyo overexcitation yekudzivirira yakakamurwa kuva yakakwirira uye yakaderera marongero.Nzvimbo yakaderera inotumira chiratidzo mushure mekugadzirisa kunonoka kwe5s uye inoderedza kupisa kwemhepo (basa rekudzikisa mhepo inopisa uye inoputika ikozvino isingashandiswi kwenguva pfupi), uye nzvimbo yakakwirira inoshanda mu-de-loading mushure memuganhu wenguva inverse.Demagnetization.Muganho wepamusoro we inverse time kunonoka ndeye 5 seconds, uye yakaderera muganho 200 seconds.

3. Silent dizeli jenareta stator grounding kudzivirirwa.

Jenereta stator grounding dziviriro inoshandiswa sejenareta stator imwe-chikamu chekudzivirira kukanganisa.Iyo ine zvikamu zviviri: iyo yakakosha zero sequence voltage chikamu uye yechitatu harmonic voltage.Iyo yakakosha zero sequence voltage inochengetedza imwe-chikamu stator mhepo munzvimbo ye95% kubva kumagumo emuchina kusvika kumuswe wemuchina.Mhosva yepasi inoumbwa nekuratidzira musimboti we zero-sequence voltage pamagumo ejenareta, iyo inoshanda pane demagnetization mushure menguva yakatarwa ye t1 (3s);yechitatu harmonic voltage inodzivirira imwe-phase grounding kukanganisa kwe stator winding kubva kumuswe wejenareta kusvika ku30% yemagumo ejenareta.Nzvimbo isina kwayakarerekera yejenereta uye yechitatu-harmonic musimboti pamagumo ejenereta inoumbwa, uye ita pachiratidzo mushure menguva yakatarwa ye t2 (5s).Iwo maviri anoumba 100% stator grounding dziviriro.Dziviriro yacho yakashongedzerwa nePT disconnection lock.

4. Silent dizeli jenareta stator tendeuka kudzivirira.

Dziviriro inoumbwa neiyo longitudinal zero sequence voltage uye yakashata kutevedzana danho rechikamu chemhosva.PT yekuvhara matanho ekuvharisa anogadzikwa sechidziviriro chikuru chejenareta yemukati kutendeuka uye chikamu chipfupi chedunhu uye yakavhurika welding ye stator winding.Iyo yakashata sequence yekutevedzana kweiyo chikamu chekukanganisa inopfuudzwa Kuona yakashata-kutevedzana simba rinoyerera richibuda mujenareta kuona iyo longitudinal zero-kutevedzana voltage criterion inoonekwa nekuona iyo longitudinal 3UO inobuda ne3PT yakavhurika delta inotenderera iyo isina kwayakarerekera poindi yakananga. yakabatana nenzvimbo isina kwayakarerekera yejenareta asi isina kudzika.Chiito chekudzivirira chiri pa full stop.

5. Silent dizeli jenareta kunze-kwe-nhanho kudzivirira.

Dziviriro inoshandisa matatu-impedance element kuona huwandu hwematanda anotsvedza uye kuona nzvimbo ye oscillation centre kuburikidza nekushandurwa kweiyo impedance trajectory.Panyaya yepfupi-circuit kukanganisa, system oscillation, voltage circuit disconnection, nezvimwewo, kudzivirira hakuzoshanda.Dziviriro inowanzoita pachiratidzo;apo oscillation centre iri mukati mejenereta-transformer boka, danho rekudzivirira ini ndinotanga uye ndinotumira rwendo rwekufamba kuburikidza ne t1 (0.5s), iyo inoshanda pa de-excitation;apo nzvimbo ye oscillation iri kunze kweboka re generator-transformer, kuchengetedzwa Kutanga kwechikamu chechipiri kunoratidzwa pa t2 (2s).Chidziviriro chekudzivirira chakashongedzerwa neazvino chinovharira mudziyo kuti ive nechokwadi chekuti ikozvino haipfuure yakayerwa kunze-kwe-nhanho yekupwanya ikozvino yedunhu redunhu kana wedunhu wakadzimwa.

6. Low-frequency cumulative protection yeakanyarara dizeli jenareta.

Iyo yakaderera-frequency accumulation dziviriro inopindirana neiyo cumulative mhedzisiro yeiyo yakaderedzwa frequency yehurongwa pamhepo turbine.Dziviriro yacho ine inonzwika frequency relay uye counter, uye yakavharwa neiyo yekubatsira kubata kweiyo outlet circuit breaker (kureva, iyo yakaderera-frequency kuunganidza dziviriro inobudawo kana jenareta rabuda kushanda), uye iyo cumulative system frequency yakaderera Kana. iyo frequency yakaiswa pa 47.5 Hz, kana nguva yakaunganidzwa inosvika pakukosha kweseti ye3000 masekonzi, chiratidzo chichatumirwa mushure mekunonoka kwe30 seconds.Chishandiso chinogona kutariswa munguva chaiyo panguva yekushanda: yakatarwa kukosha, frequency f uye cumulative nguva kuratidza.

7. Silent dizeli jenareta excitation redunhu overload kudzivirira.

Excitation circuit overload protection inoshandiswa kuchengetedza rotor excitation circuit kubva kune overcurrent kana overload.Iyo yakabatanidzwa mumhando yezvikamu zvitatu uye ine zvikamu zviviri: yakatarwa nguva uye inverse nguva yakatarwa.Iko kushanda ikozvino kwechikamu chenguva yakatarwa inogadziriswa maererano nemamiriro ezvinhu ekuti inogona kudzorerwa zvakavimbika pasi pehuwandu hwehuwandu hwemazuva ose hwekushanda kwemazuva ose.Mushure menguva yenguva t1 (5s), inoshanda pachiratidzo uye inoderedza ikozvino kunakidza (basa rekudzikisa ikozvino rinokurudzira harina kushandiswa);hunhu hwechiito chechikamu chenguva inopindirana zvinoenderana nejenareta Iyo yekuremedza kugona kweiyo excitation winding inotarwa, uye chiito chekudzivirira chiri mukubvisa-simba uye de-excitation.Muganho wepamusoro weiyo inverse time limit is 10 seconds.

8. Imwe-nzvimbo yekudzivirira yekudzivirira kune rotor ye silent diesel generator.

Iyo jenareta rotor imwe-nzvimbo yekudzivirira yekudzivirira inoshandiswa kuratidza imwe-poindi yepasi kukanganisa kweiyo jenareta rotor redunhu.Dziviriro inotora iyo ping-pong switching musimboti.Iyo yakanaka uye yakaipa pasi voltages yedunhu re rotor inotorwa sample, uye iyo rotor grounding kuramba inoverengerwa munguva chaiyo nekugadzirisa maviri akasiyana pasi loop equations.Uye grounding position.Dziviriro ichaita pachiratidzo mushure mekunonoka kwemasekonzi maviri.

9. Symmetrical overload kuchengetedzwa kwemajenareta edhiziri akanyarara.

Chishandiso chekudzivirira chinoumbwa nezvikamu zviviri: yakatarwa nguva uye inverse nguva muganho.Iyo chaiyo yenguva chikamu inobata pachiratidzo mushure menguva ye5 masekonzi.Iyo inverse time chiitiko chiitiko chinotemerwa zvichienderana nekugona kwejenareta kumirisana nekuremerwa ikozvino, uye chiito chiri mukubvisa.Chidziviriro chekudzivirira chinogona kuratidza kupisa kuunganidza maitiro ejenareta stator.

10. Negative kutevedzana overload kudzivirira kuti chinyararire dhiziri jenareta.

Chishandiso chekudzivirira chinoumbwa nezvikamu zviviri: yakatarwa nguva uye inverse nguva muganho.Iyo chaiyo yenguva yekumisikidza chiito ikozvino inotarwa zvichienderana neyakarebesa inotenderwa yakashata sequence ikozvino kukosha kwe jenareta uye kukosha kwezvino kunodzivirira kusaenzana kwemaitiro asina kunaka ezvino sefa pasi pemutoro mukuru.Yechipiri inobata pachiratidzo.The inverse time action character inotarwa zvichienderana nekugona kwejenereta kumirisana neakaipa kutevedzana ikozvino, uye chiito chiri mu de-excitation uye de-excitation.

Kana iwe uchida kuziva zvakawanda nezve majenareta edhiziri, unogamuchirwa kuti ubate neemail dingbo@dieselgeneratortech.com.
