Tareen

Nidaamka korantada jiidista tareenka ee tareenka ayaa isticmaala unugyo toosiye si ay u siiso awooda DC EMU-yada, markaa iswaafajinta waa lama huraan.Marka nuxurka iswaafajinta ka badan yahay xad gaar ah, waxa laga yaabaa inay waxyeelo u geysato nidaamka awooda magaalada.Intaa waxaa dheer, nalalka, UPS, wiishashka inta badan waxay soo saaraan 3, 5, 7, 11, 13 iyo kuwo kale oo iswaafajisan.Awoodda rarka ayaa weyn, sidoo kale awoodda falcelinta waa weyn tahay.

Harmonics waxay sababtaa ilaalinta gudbinta iyo aaladaha otomaatiga ah ee nidaamka korantada inay xumaadaan ama diidaan inay shaqeeyaan, taas oo si toos ah khatar gelinaysa hawlgalka badbaadada leh ee shabakada korontada;waxay keentaa qalab koronto oo kala duwan inay dhaliyaan khasaare iyo kulayl dheeri ah, waxayna sababtaa in matoorku uu dhaliyo gariir farsamo iyo buuq.Dabeecadda iswaafajinta ayaa ku jirta shabagga korantada.Tamar ahaan nooc ka mid ah, ayaa ugu dambeyntii lagu isticmaali doonaa khadadka iyo qalabka kala duwan ee koronto, taas oo kordhinaysa khasaaraha, awoodda falcelinta ee xad-dhaafka ah iyo is-waafajinta, taas oo keeneysa kororka khasaaraha transformer-ka iyo hoos u dhaca waxtarka, waxaana lagu dari doonaa dhinaca sare ee korantada, taas oo keenaysa in ka badan Large - dhibaatooyinka tayada awoodda miisaanka.

Qalabka nalka, UPS, marawaxadaha, iyo wiishashyadu waxay dhaliyaan qulqulo is-waafaji ah, taasoo keenaysa qallooca danab.Isla mar ahaantaana, qulqulka iswaafajinta ayaa lagu dari doonaa dhinaca korantada sare iyada oo loo marayo transformer-ka.Ka dib marka la rakibo shaandhada firfircoon (HYAPF), shaandhada ayaa soo saari doonta hadda magdhow leh oo leh baaxad isku mid ah laakiin ka soo horjeeda xaglaha wejiga ee iswaafajinta la ogaaday.Shabakadda korontadu waxay ku xiran tahay is-waafajinta culeyska si loo gaaro ujeeddada shaandheynta iyo nadiifinta korantada, taasoo si wax ku ool ah u yareeyn karta heerka guul-darrida qalabka.Shaandheeyayaasha awooda firfircooni waxay leeyihiin waxqabad ka wanaagsan shaandhada aan caadiga ahayn, waxay si firfircoon u magdhabi karaan harmonics, wayna u nugul yihiin dhawaaqa.
