Pofuna kukwaniritsa zosowa za zombo zazikulu ndi zazing'ono komanso kuphatikizika kwachuma padziko lonse lapansi, komanso zopinga za chitukuko cha zachuma ndi chikhalidwe cha anthu pazachuma ndi chilengedwe komanso chitukuko cha chitukuko cha zachilengedwe m'madoko a m'mphepete mwa nyanja, chitukuko ndi mapangidwe a madzi akuya. njira ndi malo oimika magalimoto, ndi mapangidwe doko makina zoyendera Laikulu ndi mkulu-mwachangu, zambiri ndi kulamulira kaphatikizidwe mu kasamalidwe doko, chitukuko mwadongosolo potengera makhalidwe a mitundu yosiyanasiyana ya katundu, zazikulu, nzeru ndi zachilengedwe machitidwe ndi mbali zazikulu za kusintha kwa madoko amtsogolo ndi zatsopano.
Chifukwa cha zosowa zagawidwe, pali katundu wambiri wonyamula ndege pamakampani onyamula monga madoko, ndipo ma inverters amayikidwa pazinthu zambiri.Chiwerengero chachikulu cha otembenuza pafupipafupi amawonjezera kwambiri zomwe zili mu harmonic mu dongosolo logawa mphamvu zamakampani adoko.Pakadali pano, kukonzanso kwa ma inverters ambiri kumagwiritsa ntchito kukonzanso kwa ma pulse asanu ndi limodzi kuti asinthe mphamvu ya AC kukhala mphamvu ya DC, kotero ma harmonics omwe amapangidwa amakhala makamaka achisanu, chisanu ndi chiwiri, ndi khumi ndi chimodzi.Kuwonongeka kwa ma harmonics mu pulogalamu ya petrochemical system kumawonekera makamaka pakuwonongeka kwa uinjiniya wamagetsi komanso kulakwitsa kwa kuyeza kolondola.Kafukufuku wasonyeza kuti mafunde a ma harmonic angapangitse kuwonongeka kwina kwa thiransifoma, zomwe zingayambitse kutenthedwa, kufulumizitsa ukalamba wa sing'anga yotetezera, ndikuwononga kuwonongeka.Kukhalapo kwa ma harmonics kumawonjezera mphamvu yowoneka bwino ndipo kumakhala ndi zotsatira zoipa kwambiri pakuchita bwino kwa transformer.Kuphatikiza apo, kugunda kwapano kumakhudza mwachindunji ma capacitors, ma disconnectors ndi zida zotetezera relay mu dongosolo lamagetsi.Pazida zambiri zoyesera, muzu weniweniwo umatanthauza masikweya amtengo wapatali sungathe kuyeza, koma mtengo wapakati ukhoza kuyeza, ndiyeno mawonekedwe ongoyerekeza amachulukitsidwa ndi index yabwino kuti apeze mtengo wowerengera.Pamene ma harmonics ali aakulu, kuwerengera koteroko kumakhala ndi zosiyana zazikulu, zomwe zimapangitsa kuti miyeso ikhale yosiyana.
Mavuto omwe mungakumane nawo?
1. Kuyambitsa mavuto osiyanasiyana oyendetsa ndege ndi mapampu
2. Kusintha kwafupipafupi kumapanga ma harmonics ambiri, omwe amakhudza ntchito yotetezeka ya zipangizo zamagetsi za dongosolo.
3. Chilango chamagetsi chokhazikika chifukwa cha mphamvu yotsika (malinga ndi njira yosinthira ndalama zamadzi ndi magetsi opangidwa ndi Unduna wa Zamadzi ndi Mphamvu Zamagetsi akampani yathu ndi Bungwe la Mtengo wa kampani yathu);
Yankho lathu:
1. Ikani zida zolipirira za HD high-voltage reactive power automatic pa 6kV, 10kV kapena 35kV mbali ya dongosolo kuti mulipire mphamvu yochitapo kanthu ya dongosolo, kukonza mphamvu yamagetsi, kupanga mphamvu ya reactance, ndikuwongolera pang'ono mphamvu yamagetsi. ya ndondomeko;
2. Mbali yamagetsi yamagetsi yamagetsi imagwiritsa ntchito mphamvu yowonongeka yowonongeka kuti iwononge katundu wokhazikika mu nthawi yeniyeni ndikusunga kudalirika kwa mphamvu yamagetsi;
3. The yogwira fyuluta Hongyan APF zodziwikiratu kulamulira dongosolo zimachitika panopa anaika pa voteji pansi 0.4kV mbali, ndi malo amodzi deta chitetezo chipukuta misozi zida Hongyan TSF chipukuta misozi dongosolo mapulogalamu zotakasika katundu amasankhidwa kusintha mphamvu chinthu.
