Abahlinzeki bemishini yempendulo yamandla bakukhumbuza ukuthi ngokuthuthuka komphakathi, ukushoda kwamandla kuya ngokuya kuba kubi kakhulu. Ukuze kuncishiswe izinkinga zikagesi futhi kuzuzwe amasu entuthuko esimeme, amaphrojekthi okonga ugesi wezinhlelo zezimoto afakwe ohlwini lwamaphrojekthi ayishumi abalulekile okonga ugesi okukhathazayo yiKhomishana Kazwelonke Yokuthuthukiswa Nezinguquko. Njengamanje, ezinhlelweni zokuhambisa ugesi ezishintshashintshayo ezimbonini, ngenxa yokusebenza okuphezulu kokulawulwa kwezimoto zabaguquli bemvamisa, kancane kancane ziye zaba ukucushwa okujwayelekile kwemishini eminingi yezimboni, okuletha izinzuzo ezinkulu kwezomnotho emabhizinisini nakubasebenzisi, futhi indawo yemakethe inkulu. Nakuba indlela yokulawula isivinini yesiguquli sefrikhwensi inomphumela ongcono wokonga amandla kunezinye izindlela zokulawula isivinini, isistimu yokulawula isivinini ikhiqiza amandla kagesi nakanjani phakathi nenqubo yokubhuleka imoto. Iziguquli zamafrikhwensi endabuko azinawo amandla okusebenzisa la mandla kagesi avuselelwe, kodwa ziwadla ngezinqamuleli zamabhuleki, zimosha le ngxenye yamandla. Iyunithi yempendulo yamandla yesiguquli sefrikhwensi ingasebenzisa ngempumelelo la mandla kagesi avuselelwe, yenze isistimu yokulawula isivinini isebenzise amandla kakhudlwana.
Iyunithi yempendulo yamandla iwuhlobo lweyunithi yokubhuleka eklanyelwe ngokukhethekile iziguquli zefrikhwensi, ikakhulukazi ezisetshenziswa ku-inertia ephezulu kanye nokuhudula amasistimu okulawula isivinini esishintshashintshayo. Isiza injini ukuthi iphendule ngamandla kagesi avuselelwe akhiqizwa ngesikhathi senqubo yawo yokunciphisa izinga kugridi yamandla, kuyilapho futhi isiza isistimu ekufezeni umsebenzi wokubhuleka ngokushesha.
Kusistimu yokulawula isivinini esishintshashintshayo, lapho umthwalo wenjini ungamandla anamandla, njengamayunithi okumpompa insimu kawoyela, izinyusi zezimayini, njll; Noma imithwalo emikhulu ye-inetia efana namafeni, amapayipi kasimende, imishini yokulinganisa ashukumisayo, njll; Lapho imithwalo yamabhuleki esheshayo idingeka ezigayweni zensimbi, amapulani amakhulu e-gantry, ama-spindle amathuluzi omshini, njll., injini nakanjani ingena inqubo yokukhiqiza amandla. Okusho ukuthi, i-motor rotor ihudulwa amandla angaphandle noma umzuzu womthwalo we-inertia uyagcinwa, okubangela ukuthi isivinini sangempela semoto sibe sikhulu kunokukhishwa kwesivinini sokuvumelanisa ngesiguquli sefrikhwensi. Amandla kagesi akhiqizwa injini azogcinwa ku-DC bus filtering capacitor yesiguquli sefrikhwensi. Uma la mandla engasetshenzisiwe, i-voltage yebhasi ye-DC izokhuphuka ngokushesha, ithinte ukusebenza okuvamile kwesiguquli sefrikhwensi.
Iyunithi yempendulo yamandla ithola ngokuzenzakalelayo i-voltage yebhasi ye-DC yesiguquleli se-frequency, iguqule i-voltage ye-DC yesixhumanisi se-DC yesiguquli sefrikhwensi ibe i-voltage ye-AC enefrikhwensi efanayo nesigaba njenge-voltage yegridi, bese iyixhuma kugridi ye-AC ngemva kwezixhumanisi eziningi zokuhlunga umsindo, ngaleyo ndlela kufezwe injongo yempendulo yamandla kugridi. Ingashintsha ngokuphelele ibhuleki yokumelana, inciphise indawo yokufaka ngaphezu kuka-60%, isuse izinto zokushisisa, futhi izuze izinga eliphelele lokonga amandla elifinyelela ku-20% ~ 60%. Ikhipha ngokugcwele amagagasi e-sine futhi inikeze amandla kagesi ahlanzekile, ngokusebenza kahle kokuguqulwa kwamandla okungaphezu kwama-97.5%. Ngesikhathi esifanayo, ingathuthukisa kakhulu izinga lokushisa lezindawo zokulawula izimboni futhi inciphise izinga lokuhluleka okubangelwa izinga lokushisa eliphezulu.
