I-harmonic esebenzayo ukuhluzaibe yinxalenye ebalulekileyo yemveliso esemgangathweni yamandla eveliswa kwiindawo zoshishino nezorhwebo.Amandla asebenzayoizihluzizibalulekile ukunciphisa i-harmonics kunye nokugcina ukusebenza kakuhle kweenkqubo zombane.Ngokukodwa, izihluzi ezisebenzayo ze-harmonic zesigaba sesithathu zinokunceda ukunciphisa iingxaki zomgangatho wamandla kwizibhedlele.Izibhedlele zifuna iinkqubo zamandla ezikumgangatho ophezulu ukuxhasa izixhobo zonyango kunye nokugcina imisebenzi ebalulekileyo ebomini.Iinkqubo zombane ezibhedlele zinokufumana iziphazamiso ezininzi, kubandakanya ukuntywila, ukudumba, ii-voltage transients, kunye nokuphazamiseka kwe-electromagnetic.I-Harmonics eveliswa sisixhobo sombane inokuphazamisa umgangatho wamandla esibhedlele kwaye ibangele umonakalo wesixhobo, okukhokelela ekungaphumeleli kwenkqubo kunye nokunciphisa ukhathalelo lwesigulane.Izihlungi ezisebenzayo ze-harmonic zizinto ezibalulekileyo ezinceda ukugcina umgangatho wamandla kwizibhedlele.Le teknoloji isoloko ibeka iliso kwi-harmonic ukuphazamiseka kwaye ihluze ezo zibonakaliso ezingafunekiyo ngaphambi kokuba zonakalise inkqubo.Izihluzi ezisebenzayo ze-harmonic zilungisa ukugqwetheka kwe-waveform kwaye zibonelela ngamandla akumgangatho ophezulu kumaziko esibhedlele ngokudibanisa itekhnoloji enje ngee-capacitors, inductors, kunye nezinto ezisebenzayo.Izihlungi ezisebenzayo ze-harmonic zenzelwe ukusebenza ngokuhambelana noqwalaselo oluhambelanayo kunye nesekethe ye-mains ngelixa ukwazisa okwangoku okongezelelweyo kwinkqubo.Le yangoku inceda ukuvelisa i-harmonics elinganayo kwi-amplitude kodwa echasene nesigaba kulabo bakhoyo kwinkqubo yombane, ngaloo ndlela inciphisa kakhulu i-harmonics.I-waveform yangoku ehluziweyo esebenzayo ibekwe phezulu kwi-waveform yangoku engahluzwanga ukwenza i-waveform ene-harmonic ephantsi epheleleyo.Uphononongo lwamva nje lubonisa ukuba izihluzi ze-harmonic ezisebenzayo ziphunyezwe ngempumelelo ezibhedlele.Isibhedlele esineebhedi ezingama-300 e-China sasifumana imiba yomgangatho wamandla ngenxa yokuphazamiseka kwe-harmonic okuveliswe sisixhobo esibanzi sombane esifakwe ngaphakathi kwiziko.Oku kuphazamiseka kudlula kakhulu amanqanaba amkelekileyo, kubangela ukuba iintambo kunye ne-transformers zigqithise, zinciphise ubomi bezixhobo kwaye zibangele ukugcinwa rhoqo kunye nokutshintshwa.Isibhedlele sifake i-100Aisigaba sesithathu esisebenzayo isihluzi se-harmonicukunciphisa ezi ngxaki.Isixhobo sinciphisa i-harmonic distortion (THD) ukusuka kwi-16% ukuya ngaphantsi kwe-5%.Isihluzi esisebenzayo sikwanyusa amandla amandla ukusuka malunga ne-0.86 ukuya kufutshane ne-1, ukunciphisa ukusetyenziswa kwamandla kwinkqubo.Izihlungi ezisebenzayo ze-harmonic zandisa ukusebenza kakuhle kweenkqubo zombane kunye nokwandisa ukuthembeka kwenkqubo ngokuthintela ukusilela kwezixhobo, ukugcina izibhedlele ixesha elibalulekileyo lokugcinwa kunye nemali.Isishwankathelo,izihluzi zeharmonic ezisebenzayozibonelela ngeenzuzo ezibalulekileyo ekugcineni umgangatho wamandla ezibhedlele.Ziya zisanda izixhobo zombane ezisetyenziswa ezibhedlele, kwaye iiharmonics ezizivelisayo zinokubangela iingxaki ezinkulu zomgangatho wamandla.Izihluzi ezisebenzayo ze-harmonic ziyinxalenye ebalulekileyo yeemveliso zomgangatho wamandla ezihluza ukugqwetheka okungafunekiyo kwaye zinike amandla omgangatho ophezulu kwizibhedlele.Izihlungi ezisebenzayo ze-harmonic zinokunciphisa ukusetyenziswa kwamandla, ukunciphisa umgudu wokulondoloza, kwaye ekugqibeleni zincede izibhedlele zibonelele ngononophelo lwezigulane ezikumgangatho ophezulu.
