Hababka habaynta soo noqnoqda ee caadiga ah ee rogaha badi waxa ka mid ah: dejinta kiiboodhka wada shaqaynta, dejinta calaamada xidhiidhka, dejinta signalada analooga, dejinta calaamada garaaca iyo habaynta habka isgaadhsiinta. Hababkan soo noqnoqda ee la bixiyay waxay leeyihiin faa'iidooyin iyo faa'iidooyin iyaga u gaar ah, markaa waa in la doortaa oo loo dejiyaa hadba baahida dhabta ah. Dhanka kale, habab kala duwan oo la bixiyay ayaa la dooran karaa iyadoo loo eegayo baahiyaha shaqeynta ee isku dhejinta iyo beddelka.
Habka xakamaynta
Korantada wax soo saarka ee korantada hoose ee beddelka soo noqnoqda guud waa 380 ~ 650V, awoodda wax soo saarku waa 0.75 ~ 400kW, inta jeer ee shaqadu waa 0 ~ 400Hz, wareeggeeda ugu weyn waxay qabataa ac-dc - ac circuit. Habka xakamayntiisu waxa uu soo maray afarta qarni ee soo socda.
Qaabka kontoroolka Sinusoidal pulse width modulation (SPWM).
Dabeecaddeedu waa qaab-dhismeedka wareegga kontoroolka waa mid fudud, kharashkuna waa yar yahay, qallafsanaanta sifada makaanikada sidoo kale waa wanaagsan tahay, waxay ku qancin kartaa gudbinta guud ee codsiga xakamaynta xawaaraha siman, ayaa si ballaaran loo isticmaalay goob kasta oo warshadaha ah. Si kastaba ha noqotee, inta jeer ee hooseeya, sababtoo ah korantada wax soo saarka hooseeya, qulqulka ayaa si weyn u saameeya hoos u dhaca danab ee caabbinta stator, kaas oo yareynaya qulqulka ugu sarreeya ee wax soo saarka. Intaa waxaa dheer, sifooyinka farsamada, ka dib oo dhan, ma jiro matoor toos ah oo toos ah, iyo waxqabadka xakamaynta awoodda xawaaraha ee joogtada ah iyo firfircooni maaha mid lagu qanco, iyo waxqabadka nidaamka ma aha mid sarreeya, qalooca xakamaynta ayaa isbeddelaya culeyska, jawaabta qulqulka ayaa ah mid gaabis ah. , Heerka isticmaalka torque motor ma aha mid sare, xawaaraha hoose oo leh caabbinta stator iyo jiritaanka inverter saamayn waqtiga dhintay iyo hoos u dhac waxqabadka, xasiloonida liidata. Sidaa darteed, dadku waxay horumariyeen xakamaynta xakamaynta vector-ka ee isbeddelka xawaaraha soo noqnoqda.
Habka kontoroolka hawada sare ee korantada (SVPWM).
Marka la eego aragtida guud ee saamaynta jiilka ee qaab-dhismeedka saddex-waji, waxay abuurtaa qaab-dhismeedka saddex-waji ee mowjadda hal mar waxayna ku qiyaaseysaa wareegga wareegga magnetic-ka ugu habboon ee farqiga hawada matoorka ujeedada, iyo goynta gudaha gudaha waxay ku dhowdahay goobada . Ka dib marka loo isticmaalo ficil ahaan, waa la hagaajiyay, taas oo ah, magdhowga soo noqnoqda ayaa la soo bandhigay si loo tirtiro qaladka xakamaynta xawaaraha. Saamaynta iska caabbinta stator ee xawaaraha hooseeya waxaa meesha ka saaraya qiyaasta jawaab celinta ee baaxadda isku xirka qulqulka. Korontada wax-soo-saarka iyo hadda waa loop xiran si loo hagaajiyo saxnaanta firfircoon iyo xasilloonida. Si kastaba ha ahaatee, waxaa jira xiriiro badan oo ku jira wareegga xakamaynta mana jiro xeerar la soo bandhigay, sidaas darteed waxqabadka nidaamka looma wanaajin asal ahaan.
Habka xakamaynta Vector (VC).
Xakamaynta xawaaraha soo noqnoqda ee isbeddelka vector, waa stator-ka hadda jira ee matoorka asynchronous ee nidaamka saddexda weji ee Ia, Ib, Ic, iyada oo loo marayo saddexda weji - isbeddelka laba weji, oo u dhiganta nidaamka isku-duwayaasha laba waji oo taagan, ac hadda Ia1Ib1 mar labaad adigoo riixaya Wareegga rotor-ku-jiheeyaha ee isbeddelka, oo u dhiganta isku-duwayaasha wareega wareega ee dc hadda Im1, It1 (Im1 waxay u dhigantaa hadda kacsan ee dc motor; It1 waxay u dhigantaa hadda armature kaas oo u dhigma torque), ka dibna Xakamaynta tirada matoorka dc waxaa lagu helaa iyadoo lagu dayanayo habka xakamaynta ee dc motor. Nuxur ahaan, matoorka ac wuxuu u dhigmaa matoor dc, xawaaraha iyo goobta magnetic ayaa si madax banaan loo kontaroolaa. Laba qaybood oo ka mid ah torque iyo magnetic field waxaa lagu helaa iyada oo la xakameynayo isku xirka qulqulka rotor-ka iyo kala-goynta stator current. Habka kontoroolka vector-ka ayaa ah mid muhiimad gaar ah leh. Si kastaba ha noqotee, codsiga wax ku oolka ah, isku xirka qulqulka rotor waa adag tahay in si sax ah loo eego, sifooyinka nidaamka ayaa si weyn u saameeya xuduudaha mootada, iyo isbeddelka wareegga wareegga ee loo isticmaalo habka xakamaynta ee mashiinka dc u dhigma waa mid adag, sidaas darteed xaqiiqda dhabta ah. saamaynta xakamaynta way adagtahay in la gaaro natiijada falanqaynta ugu habboon.
Habka xakamaynta torque-ga tooska ah (DTC).
Sannadkii 1985, DePenbrock, oo ah borofisar wax ka dhiga jaamacadda Ruhr ee Jarmalka, ayaa markii ugu horreysay soo jeediyay tignoolajiyada beddelka soo noqnoqda ee DTC. Ilaa xad, tignoolajiyadani waxay xallisaa yaraanta xakamaynta vector, waxayna si degdeg ah ugu horumartaa fikradda xakamaynta cusub, qaab dhismeedka nidaamka fudud iyo firfircoonida iyo waxqabadka aad u fiican. Tiknoolajiyada ayaa si guul leh loogu dabaqay awoodda sare ee ac gudbinta dhaqdhaqaaqa korantada. Xakamaynta torque-ga tooska ah (DTC) waxay si toos ah u falanqaysaa qaabka xisaabeed ee matoorka ac ee nidaamka isku xidhka stator waxayna koontaroolaysaa isku xidhka birlabeedka iyo qulqulka mootada. Uma baahnid matoorka ac inuu u dhigmo matoorka dc, sidaa darteed waxay badbaadisaa xisaabaadyo badan oo adag oo ku jira isbeddelka wareegtada vector. Looma baahna in lagu daydo xakamaynta dc motor, uma baahna in la fududeeyo qaabka xisaabta ee matoorka ac si loo kala saaro.
Isgoysyada Matrix - xakamaynta isgoyska
Beddelaadda soo noqnoqda ee VVVF, beddelidda soo noqnoqoshada kontoroolka vector-ka iyo beddelka soo noqnoqoshada kontoroolka tooska ah ee dhammaan waa beddelka soo noqnoqda ac - dc - ac. Dhaliilaha caadiga ah waa qodob awood gelin hoose ah, hadda is-waafajin weyn, wareegga dc weyn wuxuu u baahan yahay koronto kaydinta tamarta weyn, tamarta dib loo cusboonaysiin karo dib looguma celin karo shabagga, taas oo ah, ma fulin karto hawlgal afar-geesood ah. Sababtan awgeed, matrix ac - ac beddelka soo noqnoqda ayaa yimid. Natiijadu waxay tahay matrix ac-ac beddelka soo noqnoqda waxay badbaadisaa isku xirka dc dhexe, sidaas darteed waxay badbaadisaa mugga weyn, capacitor elektrolytic ah oo qaali ah. Waxay gaari kartaa cunsur awood l, gelinta sinusoidal hadda waxayna ku socon kartaa afar afar geesood, cufnaanta awoodda nidaamku waa weyn tahay. Inkasta oo tignoolajiyadu aanay qaan-gaadhin, haddana waxay soo jiidataa aqoonyahanno badan oo si qoto dheer u darso. Nuxurkeedu ma aha kantaroolka tooska ah ee hadda jira, isku xirka magnetka oo u dhigma, laakiin qulqulka ayaa si toos ah u ah tirada la xakameeyey si loo gaaro. Habka gaarka ah waa:
1. Xakamee isku xirka qulqulka istator-ka adiga oo soo bandhigaya kormeeraha qulqulka stator si loo ogaado habka aan xawaaraha lahayn;
2. Aqoonsiga otomaatiga ah (ID) Aqoonsiga tooska ah ee cabirrada mootada oo ku salaysan qaabka xisaabta saxda ah ee matoorka;
3. Xisaabi qiyamka dhabta ah ee u dhigma stator impedance, inductance labada dhinac, factor saturation magnetic, inertia, iwm.
4. Xaqiiji calaamada PWM ee ay dhaliso kontoroolka band-band iyadoo la adeegsanayo isku xirka magnet-ka iyo torque, oo xakamee xaalada beddelka ee beddelka.
Waxa loo baahan yahay in la xakameeyo matoorka iyo inverter laftiisa
1) tirada tiirarka matoorka. Nambarka mootada guud kama badna (aad ugu habboon, haddii kale awoodda beddelka ayaa si habboon loo kordhin doonaa.
2) Sifooyin torque, torque muhiim ah iyo dardargelinta qulqulka. Xaaladda awood isku mid ah, marka loo eego habka qulqulka culeyska sare ee culeyska, qeexida inverter-ka ayaa loo dooran karaa.
3) waafaqsanaanta korantada. Si loo yareeyo faragelinta quwadda muhiimka ah, reactor-ka waxaa lagu dari karaa wareegga dhexe ama wareegga wax-soo-gelinta ee rogaal-celinta, ama beddelka hore ee go'doominta ayaa lagu rakibi karaa. Guud ahaan, marka masaafada u dhaxaysa mishiinka iyo beddelaha soo noqnoqda ay ka badan tahay 50m, reactor, filter ama fiilada ilaalinta gaashaanka waa in lagu xidhaa dhexda.
Isbeddelka soo noqnoqda Matrix ac-ac wuxuu leeyahay jawaab celin degdeg ah oo degdeg ah (<2ms), saxnaanta xawaaraha sare (± 2%, jawaab celin PG ah), iyo saxnaanta qulqulka sare (<+3%). Isla mar ahaantaana, waxay sidoo kale leedahay torque bilawga sare iyo saxnaanta qulqulka sare, gaar ahaan xawaaraha hooseeya (oo ay ku jiraan 0), waxay soo saari kartaa 150% ~ 200% torque.
Dooro nooca inverter, marka loo eego nooca mishiinada wax soo saarka, kala duwanaanta xawaaraha, saxnaanta xawaaraha taagan, bilawga qulqulka, waxay go'aansadeen in ay doortaan habka xakamaynta inverter-ka ugu habboon. Waxa loogu yeero ku habboon labadaba waa sahlan tahay in la isticmaalo, laakiin sidoo kale dhaqaale, si loo buuxiyo shuruudaha aasaasiga ah iyo shuruudaha habka iyo wax soo saarka.
