Nonlinear poob Optimization Tswj ntawm Cuam Tshuam Magnet Synchronous Lub Cev Muaj Zog Tsav Tsav Tsheb
Txo qhov kev poob lawm ntawm qhov chaw ua haujlwm sab nrauv synchronous tsav tsheb yog qhov tseem ceeb rau qhov kev txhim kho kev ua haujlwm ntawm cov hluav taws xob ntshiab. Raws li qhov kev ntsuam xyuas ntawm cov qauv linear poob qauv, daim ntawv no constructs tus tshiab nonlinear poob qauv rau kev khiav hauj lwm cov yam ntxwv ntawm sab nraud hlau nplaum synchronous lub cev, uas tuaj yeem kwv yees lub cev poob hauv txhua yam kev ua hauj lwm. Raws li tus qauv tshiab nonlinear poob qauv, daim ntawv no tawm tswv yim txog nonlinear poob kev tswj optimization tswj ntawm qhov chaw ua hauj lwm tas li synchronous tsav tsheb, thiab ua tiav tag nrho qhov kev ntsuas ntawm qhov system ntawm kev sib txuas ntawm kev tsav tsheb thiab tsav tsheb. Cov kev sim tau pom tau tias piv nrog cov kev tswj ntau tshaj plaws ntawm kev tswj torque-to-current, cov kev tswj qhov kev tswj tsis yog cov kev tswj hwm tsis tau zoo los ua kom tsis muaj peev xwm ua kom tsis tau cov yam ntxwv ntawm kev ua haujlwm, thiab ua kom tau lub zog txuag hluav taws xob.
1 Taw qhia
Raws li lub hauv paus loj ntawm cov hluav taws xob fais fab, cov kev khiav hauj lwm ua tiav ntawm cov hlau nplaum synchronous tsav tsheb yuav ncaj qha rau cuam tshuam cov kev tsav tsheb ntawm hluav taws xob nyob hauv ib nqi, uas yuav ua rau muaj ntau daim ntawv thov ntawm hluav taws xob [1-2]. Yuav kom txhim kho tau qhov tsav tsheb ncaj nruab nrab ntawm kev sib txuas ntawm lub tshuab hluav taws xob, kev nyuaj ntawm kev khiav hauj lwm ntawm hluav taws xob, ntau lub tswv yim ntawm kev tsim cov tswv yim tswj tau raug siv rau kev txhim kho kom zoo ntawm cov hlau nplaum synchronous motor tsav, thiab cov txiaj ntsim zoo tau tiav lawm. Raws li cov qauv kev ua lej ntawm lub tshuab, cov ntaub ntawv [3-4] npaj siab tshaj txoj kev tiv thaiv txog kev tiv thaiv torque-rau-tam sim no. Thaum kho qhov stator magnetic field ntawm lub cav, lub tshuab hluav taws xob uas muaj peev xwm sib xws tas li muaj qhov tsawg kawg nkaus stator tam sim no thaum lub qhov tso zis torque tas li, yog li txo lub cav qis. Nws muaj qhov zoo ntawm kev ceev ceev thiab kev siv yooj yim. Hauv [5-7], qhov kev ntsuas optimization tswj zoo los ntawm kev ua lag luam tas li synchronous lub cev poob qauv yog npaj siab. Qhov tseeb poob ntawm lub cav yog tsim ua raws li qhov tooj liab thiab hlau poob ntawm lub cev, thiab qhov ceev thiab tam sim no ntawm lub qhov chaw ua hauj lwm tas li synchronous yog kuaj los yog kwv yees nyob rau ntawm lub sijhawm. Qhov teeb liab, raws li tus qauv poob ntawm lub cav, muab cov txiaj ntsig zoo tshaj plaws ntawm qhov siab tshaj plaws kev siv zog. Phau ntawv [8] npaj siab hais txog kev ua kom qhov kev lag luam zoo tshaj los ntawm kev tshawb fawb hauv online rau cov tswv yim tsawg. Hom no tsis yog yuav tsum tau muaj qhov xaam phim meej ntawm kev ua lag luam uas muaj kev sib txuas ntawm lub cev, thiab kev tshawb nrhiav rau kev pom hauv online tam sim no los ntawm kev kuaj lub tswv yim ntawm lub cev kom paub lub tsav tsheb. Efficiency optimization.
Txawm hais tias qhov kev tiv thaiv qis zog muaj qhov zoo ntawm qeeb teb thiab muaj zog adaptability parameter hloov, nws cov sijhawm optimization ntev heev, uas yog ib qho nyuaj ua kom tau raws li daim ntawv thov ntawm txoj cai hluav taws xob tsheb cov txheej txheem mob, thiab lub zog txuag lub zog tsis zoo . Txawm li cas los xij, cov qauv tsis raws li cov qauv ntawm cov hlau nplaum synchronous efficiency optimization tswj tsis yooj yim los tsim ib txoj kev tsav tsheb tsis zoo, thiab tsuas ua tau zoo dua qhov ua tiav ntawm qhov kev poob haujlwm ntawm lub cev, ua kom pom tias qhov system tsis tuaj yeem ua haujlwm tsis zoo. Vim li no, thiaj li ua tau raws li cov kev xav tau ntawm kev tsav tsheb uas muaj peev xwm tswj tau ntawm kev ua haujlwm ntawm cov hluav taws xob uas muaj kev sib txuas ntawm cov hluav taws xob uas muaj kev sib txuas ntawm cov hluav taws xob, tsheb. Nonlinear poob kev tswj optimization. Tus non-linear polynomial yog siv los ua kom haum rau cov yam ntxwv ntawm cov khoom siv hauv nonlinear thiab kev hloov cov yam ntxwv ntawm cov khoom siv hluav taws xob, thiaj li ntsuas kom tsav tsheb poob qis dua hauv kev khiav hauj lwm txawv. Ntawm no, nonlinear poob qauv ntawm cov hlau nplaum tsis tu ncua synchronous lub cev tsav tsheb khiav hauv tag nrho kev ua hauj lwm kev mob yog tsim los ntawm kev ntsuam xyuas lub tooj poob thiab cov yam ntxwv hlau tsis zoo ntawm cov hlau nplaum synchronous. Raws li tus qauv tsis tau, kev sib raug zoo ntawm tus stator tam sim no ntawm lub cav thiab qhov kev poob ntawm qhov system yog kawm los ntawm kev siv qhov kev xav ntawm qhov ua kom zoo. Kev pom kev sib tw ntawm kev tsav tsheb thiab kev tsav tsheb yog pom tau los ntawm nonlinear poob qhov kev tswj qhov kev tswj hwm, uas ua kom zoo dua qhov ntau ntawm cov hlau nplaum nyob rau hauv tag nrho kev ua hauj lwm. Cov yam ntxwv tsis zoo ntawm cov tshuab synchronous hauv nruab siab. Cov lus qhia tsis zoo ntawm kev tswj qhov kev tshawb xyuas no muaj tseeb ntawm tus qauv tsim ua lag luam tas mus li. Cov kev sim tau pom tau tias piv nrog cov kev txwv ntau tshaj plaws ntawm kev siv zog torque, kev poob qhov nonlinear kev qhia tswj kev ua kom tau zoo tuaj yeem ua kom tag nrho kev ua hauj lwm ntau. Lub tshuab hlau nplaum sib txuas rau nruab siab ncaj nraim mus rau kev tsav tsheb thiab kev siv zog ntawm lub cev, yog li ua tiav lub hom phiaj ntawm kev txhim kho kev nce qib ntawm kev tsav tsheb ntshiab.
2 qhov chaw ua haujlwm sab nraud synchronous lub cev ncaj qha tsav tsheb poob qauv
Yuav kom paub qhov kev pom kev tsis pom kev ntawm cov nonlinear poob ntawm qhov chaw ua haujlwm tsis tu ncua synchronous tsav ncaj qha tsav, nws yog ib qhov tsim nyog los tsim ib qho teeb meem poob qauv ntawm qhov chaw nyob nruab nrab synchronous motor tsav. Lub plab ntawm cov hlau nplaum sib txuas synchronous tsav yog tsim los ntawm ob qho: cov hlau nplaum tsis tu ncua synchronous lub cev poob thiab tsav tsheb tsis tau. Lub cev tsis muaj zog xws li cov tooj liab poob ntawm lub cav thiab lub hlau poob ntawm lub cav, thiab tus tsav tsheb poob qis tshaj nrog txoj kev tsis tau ntawm lub hwj huam thiab qhov poob ntawm lub hwj chim ntaus.
