Izinto ezibalulekile zokukhetha amadivayisi empendulo yamandla ekusetshenzisweni kokulawulwa kwezimboni nsuku zonke yilezi:
Layisha ukufaniswa kwesici
Imithwalo ye-torque engaguquki (njengama-cranes namawintshi) idinga ukukhethwa kwedivayisi yempendulo enamandla okuphendula ashukumisayo ukuze kuqinisekiswe ukumuncwa okusheshayo kwamandla avuselelayo.
Imithwalo ye-torque eguquguqukayo (njengabalandeli namaphampu) idinga ukulungisa umkhawulo wamandla wempendulo ngokusekelwe kwijika letorque yesivinini (njengesici setorque yesikwele).
Amandla kanye namazinga kagesi
Amandla alinganiselwe wedivayisi yempendulo kufanele abe ≥ izikhathi ezingu-1.1 amandla alinganiselwe emoto, futhi amandla kagesi ebhasi kufanele afane nomthamo wegridi (njengesistimu engu-400V/660V).
Okokusebenza kwamandla aphezulu (>100kW), kuyanconywa ukusebenzisa isiguquli sefrikhwensi yamaquadrant amane esisekela ukugeleza kwamandla okuqondiswa kabili.
Ukuhambisana kwegridi
Kuyadingeka ukuthola ububanzi bokuguquguquka kwamandla kagesi wegridi yamandla (± 20%) ukuze kuqinisekiswe ukuthi izinga lokuhlanekezelwa kwe-harmonic (THD) lempendulo yamanje lingaphansi kuka-5%.
Okubalulekile kufanele kunikezwe amadivayisi anomsebenzi wokuthola ukuvumelanisa kwe-voltage/imvamisa ukuze kugwenywe impendulo yamanje kanye nokuvumelanisa kwegridi.
Ukuhlukaniswa kwezobuchwepheshe kanye nezimo ezisebenzayo
Uhlobo lwezimpawu Izimo ezisebenzayo
Ukufakwa okuzimele kohlobo lokuhlukanisa, kulula ukukugcina, kodwa kudinga amaphrojekthi engeziwe okulungisa izintambo noma amasistimu okuphakamisa anendawo elinganiselwe.
Kuhlanganiswe kusiguquli sefrikhwensi, ukusabela okusheshayo kanye nezindleko eziphezulu zemishini emisha yezimboni (njengama-centrifuges)
Isitoreji samandla esihlanganiswe nephakethe lebhethri, silungele igridi engasebenzi noma izimo zegridi ezingazinzile ngaphandle kwezimo zempendulo yegridi
Ukuhlola umphumela wezomnotho nokonga amandla
Izinga lokonga amandla: Idivayisi yempendulo yamandla ekheshi ingafinyelela ku-17.85% -40.37%, futhi isikhathi sokukhokha sokutshala imali sidinga ukubalwa ngokusekelwe esilinganisweni somthwalo.
Ukuqhathaniswa kwezindleko: Intengo yedivayisi yempendulo icishe iphindwe izikhathi ezingu-2-3 kunebhuleki yokusetshenziswa kwamandla, kodwa izinzuzo zesikhathi eside zokonga amandla zibalulekile.
Amaphuzu abalulekile okufakwa nokugcinwa
Umklamo wokukhipha ukushisa
Amadivayisi empendulo enamandla amakhulu adinga ukupholiswa komoya okuphoqelekile (njengamafeni angaqhumi) ukuze kuqinisekiswe izinga lokushisa lendawo ye-IGBT engu-<125 ℃.
Gcina indawo yokukhipha ukushisa engu-≥ 100mm ngaphakathi kwebhokisi ukuze ugweme ukunqwabelana kokushisa.
Umsebenzi wokuvikela
Kuyadingeka ukuthi ube nokuvikelwa kokuxhuma okungaphezulu, okudlulele, ukushisisa, kanye nokuhlehla kokuxhumeka kwegridi yamandla. Uma i-voltage yebhasi idlula izikhathi ezingu-1.2 kunenani elisebenzayo legridi yamandla, izozinqamula ngokuzenzakalelayo.
Iziphakamiso zenqubo yokukhetha
Ijika langempela lokulayisha: Thola amandla aphezulu okuvuselela ngokuhlolwa kwesivinini se-torque.
Ukutholwa kwegridi yamandla: Qinisekisa okuqukethwe kwe-harmonic nokuzinza kwe-voltage yegridi yamandla.
Ukuqinisekiswa kokulingisa: Sebenzisa amathuluzi afana ne-MATLAB ukuze ulingise i-waveform yamanje yempendulo futhi ulungiselele amapharamitha okulawula.
