Ekukhiqizweni kwansuku zonke kanye nokuphila, ama-reactors ochungechunge nama-shunt reactor ayizinto ezimbili ezisetshenziswa kakhulu zikagesi.Kusukela emagameni ama-reactor ochungechunge nama-shunt reactors, singamane siqonde ukuthi enye iyi-reactor eyodwa exhunywe ochungechungeni lwebhasi yesistimu Phakathi kwazo, enye ukuxhumana okuhambisanayo kwe-reactor, futhi i-capacitor yamandla ixhunywe ngokuhambisana ibhasi lesistimu.Nakuba kubonakala sengathi kuphela isifunda kanye nendlela yokuxhuma ihlukile, kodwa.Izindawo ezisetshenziswayo kanye nezindima ezizidlalayo zihluke kakhulu.Njengolwazi olujwayelekile olujwayelekile, izindima zamasekethe ochungechunge namasekhethi ahambisanayo ahlukile.
Ama-reactor angahlukaniswa abe ama-AC kanye nama-DC.Umsebenzi oyinhloko wama-AC reactors anti-interference.Ngokuvamile, ingathathwa njengenxeba lekhoyili lezigaba ezintathu kumongo wensimbi onezigaba ezintathu.Ama-reactor e-AC ngokuvamile axhunywe ngokuqondile kusekethe eyinhloko, futhi ukucatshangelwa okuyinhloko lapho kukhethwa imodeli i-inductance (ukwehla kwamandla kagesi lapho i-current igeleza ku-reactor ayikwazi ukuba ngaphezu kuka-3% we-voltage elinganiselwe).I-reactor ye-DC idlala ikakhulukazi indima yokuhlunga kusekethe.Kalula nje, kuwukuphephetha ikhoyili engxenyeni yensimbi yesigaba esisodwa ukunciphisa ukuphazamiseka okubangelwa umsindo womsakazo.Kungakhathaliseki ukuthi iyirektha ye-AC noma i-DC, umsebenzi wayo ukunciphisa ukuphazamiseka kusiginali ye-AC nokwandisa ukumelana.
I-reactor yochungechunge ibekwe ngokuyinhloko endaweni ye-breaker circuit ephumayo, futhi i-reactor yochungechunge inamandla okuthuthukisa i-impedance ye-short-circuit kanye nomkhawulo wamanje we-short-circuit current.Ingacindezela ama-harmonics e-oda eliphezulu futhi ikhawulele ukuvala i-inrush current, ngaleyo ndlela ivimbele ama-harmonics ekulimazeni ama-capacitor futhi ifeze imisebenzi yokukhawula nokuhlunga kwamanje.Ikakhulukazi endaweni yamandla lapho okuqukethwe kwe-harmonic akuyona enkulu kakhulu, ama-capacitor axhumayo nama-reactors ohlelweni lwamandla ochungechungeni angathuthukisa ikhwalithi yamandla futhi kubhekwa njengesixazululo esiphumelela kakhulu.
I-shunt reactor idlala ikakhulukazi indima yesinxephezelo samandla asebenzayo, esinganxephezela i-capacitive charge current of the line, ikhawulele ukukhuphuka kwamandla kagesi wesistimu kanye nokukhiqizwa kokusebenza ngokweqile kwe-voltage, futhi iqinisekise ukusebenza okuthembekile kolayini.Isetshenziselwa ukunxephezela isinxephezelo samandla esabalalisiwe semigqa yokudlulisela amabanga amade, ukuvimbela ukukhuphuka kwamandla kagesi ekupheleni kwemigqa emide engalayishiwe (evame ukusetshenziswa ezinhlelweni ze-500KV), futhi yenze kube lula ukuvala kabusha kwesigaba esisodwa nokunciphisa ukugcwala kokusebenza.Isetshenziswa kakhulu kumaphrojekthi wamabanga amade wokudluliswa kwamandla kanye nokusabalalisa amagridi kagesi.
Amakhasimende amaningi avame ukuba nemibuzo enjalo, okungukuthi, kungakhathaliseki ukuthi i-reactor yochungechunge noma i-shunt reactor, intengo ibiza kakhulu, futhi ivolumu inkulu kakhulu.Kungakhathaliseki ukuthi ukufakwa noma ukufanisa ukwakhiwa kwesifunda, izindleko aziphansi.Ingabe lezi ziphehlisi azikwazi ukusetshenziswa?Kudingeka sazi ukuthi kokubili ukulimala okubangelwa ama-harmonics kanye nokulahlekelwa okubangelwa ukudluliselwa kwebanga elide kukhulu kakhulu kunokuthengwa nokusetshenziswa kwama-reactor.Ukungcoliswa kwe-Harmonic kugridi yamandla, i-resonance kanye nokuhlanekezelwa kwamandla kagesi kuzoholela ekusebenzeni okungavamile noma ngisho nokwehluleka kwezinye izinto eziningi zamandla kagesi.Lapha, umhleli uncoma uchungechunge lwama-reactors nama-shunt reactor akhiqizwa yi-Hongyan Electric Company.Akuyona nje ikhwalithi eqinisekisiwe, kodwa futhi ihlala isikhathi eside.
