1. Isingeniso Somkhiqizo:
Idivayisi yempendulo yamandla ochungechunge lwe-PFE iyunithi yokubhuleka impendulo esebenza kahle eklanyelwe amakheshi. Ingakwazi ukuguqula ngempumelelo amandla kagesi avuselelwe agcinwe ku-capacitor ye-elevator inverter ibe amandla e-AC futhi iwathumele emuva kugridi, iguqule ikheshi ibe "isikhungo samandla" esiluhlaza ukuze sinikeze amandla kwezinye izinto zokusebenza, futhi inomphumela wokonga ugesi. Ukwengeza, ngokushintsha ama-resistors ukuze kusetshenziswe amandla, izinga lokushisa elizungezile ekamelweni lomshini liyancishiswa, futhi izinga lokushisa lokusebenza lesistimu yokulawula i-elevator liyathuthukiswa, kunwetshwe impilo yesevisi ye-elevator. Igumbi lomshini alidingi ukusetshenziswa kwezinto zokupholisa ezifana ne-air conditioning, ukonga ugesi ngokungaqondile. Ifanele konke ukucushwa kwama-frequency converters kanye ne-resistors edla amandla embonini ye-elevator, isetshenziswe kabanzi e-Mitsubishi, i-Tongli, i-Xunda, i-Vauxhall, i-Kuaiyi, i-Asia Pacific Tongli, i-Tongyou, i-Gangri, i-Fuji, i-Hitachi, i-Otis, i-Thyssen, i-Yongda, i-Ulivit, i-Sanrong, i-Dend-sheng brand, i-Dend-sheng brand.
2. Izici zomkhiqizo:
⑴ Ukwamukela iyunithi yokucubungula emaphakathi ye-DSP yezempi enesivinini esiphezulu
Ukusebenza kahle kwempendulo, ukunemba kokulawula, ukuzinza okuhle, ama-harmonics ambalwa, ikhono eliqinile lokulwa nokuphazamiseka
⑵ Ukwamukela ubuchwepheshe bokushintshashintsha be-SVPWM
Ubuchwepheshe bokushintshwa kwe-SVPWM bungafinyelela ukuguqulwa kwe-DC kuya ku-AC, bubuyisele ngokuphelele i-voltage ephumayo yezigaba ezintathu, futhi kukhiphe i-waveform yamanje ephelele ngomphumela we-superposition wezihlungi namagridi wamandla wezigaba ezintathu.
⑶ Ukwamukela ubuchwepheshe bokuhlunga be-LC
Cindezela ngempumelelo ama-harmonics kanye nokuphazamiseka kazibuthe, nge-THD yamanje kanye ne-voltage <5%, iqinisekisa impendulo yamandla kagesi ahlanzekile
⑷ Ukwamukela ubuchwepheshe bokubona okuzenzakalelayo kwesigaba sokulandelana
Ukulandelana kwesigaba segridi yamandla yezigaba ezintathu kungaxhunywa ngokukhululekile ngaphandle kwesidingo sokuhlukanisa okwenziwa ngesandla sokulandelana kwesigaba
⑸ Yakhelwe ngaphakathi
Isivikelo sesekethe esifushane sikhona ukuze kuqinisekiswe ukusebenza okuphephile kwekheshi
⑹ Inganqamula ngokuzenzakalela emaphutheni ukuze kuqinisekiswe ukusebenza okuvamile kwekheshi
Ayinamsebenzi nesistimu yokulawula yekheshi futhi ayishintshi indlela yokulawula yokuqala yekheshi,
⑺ Ukwamukela ubuchwepheshe obuphambili obuningi, obuhambisana nazo zonke izinhlobo zeziguquli zefrikhwensi yekheshi
Umthelela obalulekile wokonga amandla, ngokusebenza kahle kokulondoloza amandla okungama-20-50%
Ukusebenza kahle kokuvuselelwa kwamandla kuphezulu njengo-97.5%
(10) Ukufakwa kalula, ukulungisa amaphutha, nokusebenza, ukugcinwa okulula nokugcinwa
Ukwamukela ubuchwepheshe bokuzihlola kuqinisekisa ukuthi i-voltage ephumayo enembile, ivimbela ukugeleza kwamanje, futhi iqinisekisa ukuthi isiguquli sefrikhwensi asithinteki nganoma iyiphi indlela.
