The classification of reverse power relays is mainly based on their operating principles, which can be summarized into three main types: amplitude comparison type, phase comparison type and cosφ type.Uhlobo ngalunye lokudluliselwa lunendlela yalo yokusebenza eyingqayizivele yokuzivumelanisa nezidingo zokuvikelwa kwegridi ezahlukene.Isibonelo, uhlobo lwe-Amplitude Marity lunquma isimo segridi yamandla ngokuqhathanisa umehluko we-amplitude wamanje noma amavoloji;Uhlobo lokuqhathanisa isigaba lusebenza ngokususelwa kumehluko esigabeni samanje noma se-voltage;Futhi uhlobo lwe-cos φ TYX DELAY yenza umsebenzi wayo wokuvikela ngokuya ngezinguquko ezikhona..
Emkhakheni we-generator ukubuyisela amandla okuvikelwa kwamandla, ukwehla kwamaphutha kwalokhu kudluliselwe kubaluleke kakhulu, ngoba ukuphuma okuzinzile kwe-generator kunomthelela oqondile esele esele yegridi yamandla.Esezinhlelweni zokwenza iphutha lokuphindisela emuva kokudlulisela kwamandla, ochwepheshe babhekana nezinselelo eziningi.Okokuqala, ukunemba kwemishini yokuhlola kuphezulu kakhulu, okudinga ukuthi imishini yokuhlola ikwazi ukukhipha ngokunembile imisinga yokuvama amandla, futhi amathuluzi wokuhlola kufanele akwazi ukukhombisa ngokunembile le misinyane elincanyana kanye noshintsho lwesigaba salo, iphutha lesigaba lilawulwa ngaphakathi kwe-0.2 °.Ngaphezu kwalokho, ukuhlolwa kwe-angle ebucayi edluliselwe kanye nezimpawu zokusebenza futhi kuyingxenye ebalulekile yenqubo yokulungisa iphutha.Ukunemba kwe-angle ebucayi kudinga ukulawulwa ngaphakathi ± 1 °, kanye nokulinganisa kwezidingo zamanje ezisebenzayo ukuze zibonise ngokunembile isimo sokusebenza kwamandla okusebenza kwe-generator.Lokhu kubalulekile ukuthi ukunemba nokuthembela kwezindlela zokuhlola zibeke phambili izidingo eziphakeme.
Ekuhlolweni kwezimpawu ezisebenzayo ezisebenzayo, kugcizelelwa okukhethekile ekulinganiseni okuhlobene nokusebenza kwamanje endaweni ethile yesigaba ukuqinisekisa impendulo efanelekile ngaphansi kombuso wokusebenza kwamandla wokuphambukisa.Lokhu kuhluke kakhulu kwindlela yokuhlola ejwayelekile yokudluliselwa okuqondayo.Ngaphezu kwalokho, i-coeffient edluliselwe edluliselwe enye inkomba ebalulekile yokuhlola ukusebenza kwayo.Inani layo akufanele libe likhulu kune-0.7 ukuqinisekisa ukuthi ukudluliswa kungakuvimbela ukungasebenzi kahle lapho kungadingekile.Ekugcineni, amanye amaphrojekthi okuhlola okudluliselwa kwamandla okubuyela emuva futhi kudingeka alandele amazinga athile nezindlela zokuqinisekisa ukuqina nokuphepha kwalo lonke uhlelo lwegridi yamandla.
