Yankho la Parallel Debugging Of Diesel Generator Sets

Tiyeni titenge kulumikizana kofanana kwa magawo awiri ofanana amphamvu monga chitsanzo kuti tifufuze zomwe zimayambitsa kufalikira kwa ma circulation.

Panopa U1:1# voteji ya unit terminal,U2:2# unit terminal voltage,R3: katundu wonyamulidwa ndi ntchito yofanana ya mayunitsi awiri,I0: panopa, i1:1 # unit output current,I2:2# unit output current.Jenereta ya dizilo ya Haifeng idakhazikitsidwa kuti ipereke chithandizo chaukadaulo.Ngati mayunitsi awiriwa akugwira ntchito mofanana, kuzungulira kwa I0 ndi 0 pansi pa katundu aliyense, ndiye kuti U1 = U2, ndiko kuti, magetsi otsiriza a mayunitsi awiriwa ndi ofanana pansi pa katundu uliwonse.Kufanana kopanda katundu ndikofanana ndi katundu wopanda malire, ndipo ma voliyumu osanyamula katundu U01 ndi U02 ayeneranso kukhala ofanana.U01=U02(1-2) Tikudziwa kuti kugawa kwapakati kwa mphamvu yogwira ntchito kumadalira mawonekedwe a injini ya dizilo ndi dongosolo lake lowongolera liwiro, ndipo kugawa kwamphamvu yokhazikika kumadalira mawonekedwe a jenereta ndi dongosolo lake losangalatsa, ndiye, mawonekedwe amagetsi amagetsi a generator set yokha.Mphamvu yowongolera voteji ndi yokhotakhota U = F (I), pomwe U ndiye magetsi omaliza a jenereta ndipo ine ndi wapano.Pofuna kuwongolera kusanthula, mzere wowongoka nthawi zambiri umagwiritsidwa ntchito kufupikitsa mpindiwo.Tangoganizani kuti pali ma seti awiri ofanana opanga omwe ali ndi mawonekedwe owongolera ma voliyumu monga akuwonetsedwa mu FIG.2 motsatana, ikani motere :δ1= TG β1,δ2 = TG β2, mawonekedwe owongolera voteji a δ1:1# unit, ndi mawonekedwe amagetsi a δ2:2# unit.

Kuchokera kusanthula pamwambapa, zitha kuwoneka kuti:

(1) Magawo awiri akalumikizidwa molumikizana, mphamvu yamagetsi yopanda katundu ndi mphamvu yowongolera mayunitsi awiriwo iyenera kusinthidwa kuti ikhale yofanana ndendende, chomwe ndi chofunikira pakuwonetsetsa kuti mphamvu zonse ziwirizi zatha komanso ngakhale kugawidwa kwa mphamvu zokhazikika. mayunitsi ndi maziko a kusintha kotsatira kwa pafupifupi kugawa mphamvu kwa mayunitsi awiriwa.Zosintha ziwiri zomwe zili pamwambazi zikakhala bwino, mphamvu yotulutsa mphamvu ya mayunitsi awiri omwe amagwira ntchito limodzi imatsimikiziridwa kukhala yofanana pansi pa katundu uliwonse, ndipo kugawa kwapakati kwamagetsi kumatsimikiziridwa palimodzi, ndipo kufalikira kumatsimikizika kukhala ziro (moyenera).Sonyezani: gwero lachiwopsezo cha kufalikira ndikuti voteji yopanda katundu wa magawo awiriwa siwofanana kwathunthu kapena mawonekedwe owongolera voteji ndi osiyana, omwe amapanga voteji yotulutsa siwofanana ndi kugunda kwamagetsi.

(2) Mphamvu yamagetsi yopanda katundu ndi mawonekedwe owongolera mayunitsi awiriwa ndi ofanana, koma kutulutsa kwa mayunitsi awiriwa sikufanana, ndiko kuti, kugawa mphamvu kwa magawo awiriwa sikufanana, komwe kudzakhalanso Kusalinganika kwa U1 ndi U2, zomwe zimapangitsa kuti pakhale kufalikira.

(3) Pali zinthu zambiri zomwe zimakhudza kugawidwa kwa mphamvu zowonongeka, monga makhalidwe a automatic voltage regulator, kukhazikika kwa chiyanjano pogwiritsa ntchito mzere wofanana, ndi zina zotero, zomwe sizidzawunikidwa pano.

DINGBO MPHAMVU ndi wopanga dizilo jenereta seti, kampani inakhazikitsidwa mu 2017. Monga katswiri wopanga, DINGBO MPHAMVU wakhala lolunjika pa genset apamwamba kwa zaka zambiri, kuphimba Cummins, Volvo, Perkins, Deutz, Weichai, Yuchai, SDEC, MTU, Ricardo , Wuxi etc, mphamvu mphamvu osiyanasiyana ndi 20kw kuti 3000kw, kuphatikizapo lotseguka mtundu, chete denga mtundu, chidebe mtundu, mafoni ngolo mtundu.Pakadali pano, DINGBO POWER genset yagulitsidwa ku Africa, Southeast Asia, South America, Europe ndi Middle East.
