Waxaa jira habab badan oo lagu yareeyo is-waafajinta, laakiin ma jirto wax xal ah oo lagu xalliyo dhammaan dhibaatooyinka.Koronto kala duwan, culeys kala duwan, waxaan u baahanahay inaan bixino xalka ugu fiican si loo yareeyo harmonic.
Jadwalka hoose isbarbardhigga THDi ee tignoolajiyada yaraynta is-waafajinta ee kala duwan ka hor.
| Lix garaac vfd ma laha reactor/ceejiso | Lix garaacis vfd Capacitor baska DC hooseeya | Lix garaaca wadnaha vfd+5% reactor/choke | 3 wejiga vfd firfircoon ee dhamaadka hore | Lix garaac vfd+ filter dadban | garaaca badan vfd | |
| Caadiga ah THDi | 90--120% | 35--40% | 35--45% | 3--5% | 5--10% | 12 garaac: 10--12% 18 garaac: 5--6% |
| Faa'iidooyinka | Xalka fudud iyo qiimaha jaban, oo la aqbali karo rakibaadaha leh tiro yar oo yar yar | Xalka fudud iyo qiimaha jaban oo keena xoogaa yaraynta iswaafajinta hadda | Xalka caadiga ah ee codsiyada HVAC | Waxqabadka iswaafajinta ugu fiican ee mid ka mid ah xalalka. Awoodda kor loogu qaado tamarta wax soo saarka inta lagu jiro xaaladaha khadka hoose. Qodobka awoodda aasaasiga ah ee midnimada. Waxay bixin kartaa bareegga dib u soo kicinta | Haddii loo maleeyo in meel bannaan oo jireed la heli karo, shaandheynta iswaafajinta dadban ayaa lagu dari karaa ka dib marka darawalka la rakibo, haddii harmonics la go'aamiyo inay dhibaato tahay. | Habka yaraynta harmonic dhaqameed. |
| Qasaarooyinka | Waxyaalaha iswaafajinta sarreeya, laguma talin in lagu rakibo tiro badan oo darawallo ah. | Qallooca korantada sare, in ka badan lixda garaaca wadnaha vfd oo leh 5% reactor/choke. | Nidaamyada leh tiro badan ama cabbirro waaweyn oo wadiiqooyin ah, ayaa laga yaabaa inay u baahdaan yaraynta iswaafajinta dheeraadka ah. | Wadadu lafteedu waxa ay dhalisaa kulayl wax yar ka badan kan caadiga ah ee lixda garaaca wadnaha ee leh reactor. | Cunsurka awoodda hogaaminaysa ee culaysyada fudud ilaa aan kabaydhiyeyaasha filtarrada la damin ee wareegga. Khatarta resonances ka dhexeeya capacitors filter iyo capacitors kale ee nidaamka. | Waxqabadka is-waafajinta ugu fican wuxuu u baahan yahay quudin koronto AC ah oo dheellitiran oo leh dhalanrog asal ah oo yar. Aad bay u adagtahay in dib loogu habeeyo garoonka dhexdiisa. |
Iyadoo horumarinta joogtada ah ee tignoolajiyada awoodda IGBT, saddexda heer ee cusubfiltar firfircoonayaa si weyn loo dalacsiiyay oo loo adeegsaday suuqa.APFku helaya signalka hadda jira wakhtiga dhabta ah iyada oo loo marayo transformer hadda dibadeed, oo kala sooca qaybta iswaafajinta iyada oo loo marayo wareegga ogaanshaha gudaha, oo soo saara magdhow hadda leh wajiga ka soo horjeeda harmonics ee nidaamka iyada oo loo marayo beddelaha awoodda IGBT si loo xaqiijiyo shaqada shaandhaynta ka baxsan harmonic.
Magdhawga wax soo saarka ee haddaAPFsi sax ah ayey u kala duwan tahay iyadoo loo eegayo iswaafajinta firfircoon ee nidaamka, markaa ma jiri doonto dhibaato magdhow ah.Intaa waxaa dheer,APFwaxay leedahay shaqada ilaalinta xad-dhaafka ah.Marka iswaafajinta nidaamku ka weyn yahay awoodda shaandhada, qalabku wuxuu si toos ah u xaddidi karaa wax soo saarka 100% awoodda la qiimeeyay iyada oo aan la dhaafin.
