2.2 Yadda da Farko da Tattalin Karamin Kashi na Bidirectional

2.2.1 Yadda da Farko da Automatic Voltage Regulator na Bidirectional Feeder

Yadda da Farko da automatic voltage regulator na bidirectional feeder yana da muhimmanci wajen kungiyoyin nayi: three-phase autotransformer voltage regulator, three-phase on-load tap changer, controller, da power flow identification module. Power flow identification module yana neman abin da ya zama don tabbatar da hukuma na kashi da kara, sannan yana baka wannan shiga controller. Controller yana yi takam ko kawo tsari ga voltage da current signals, sannan yana kontrola aiki na motor a cikin on-load tap changer don haɗa aiki na tap changer zuwa taps. Wannan yana gane tsari na transformer don samun automatic voltage regulation a kan load. Three-phase on-load tap changer yana gane tsari na transformer don canza output voltage.

2.2.2 Tattalin Karamin Kashi na Theory

Rutu mai Yaƙe:Canza-canzon line voltage kafin da ta bayar BSVR tana cikin Figure 1.

A ranar mai yaƙe, ba a bayar da BSVR bidirectional voltage regulator, voltages a jihohin main line da kuma kowane branch line sun ci. Wannan tana halaye masu mafi karfi na line voltage da kuma tana daidaita kyau na electricity consumption da take da amfani da ita a ranar mai yaƙe.

Rutu Mai Ruwa:Voltages a kowane pike na line kafin da ta bayar BSVR a ranar mai ruwa tana cikin Figure 2.

A ranar mai ruwa, bayar da BSVR bidirectional voltage regulator tana ci voltages a jihohin main line da kuma kowane branch line. Yana iya ba da kula ga normal power transmission daga small hydropower stations zuwa grid, kuma tana daidaita kyau na electricity consumption quality da take da amfani da ita a wasu masu mutum da ke kan fadin da kuma babban line.

2.3 Tattalin Karamin Kashi na Application

Daga cikin yanayin line, an samu bidirectional voltage regulator a Pole 63 na main line da capacity of 3000kVA. A yi takam da yanayin dry da wet seasons, an zaba adjustment range na -15% to +15%.

Kyakkyawan voltage na line tana ci. Yana iya ba da kula ga threshold voltage da small hydropower stations suka bayar don kula zuwa main grid (don haka hydropower stations ba suke so kuɗi voltage), kuma tana ci voltage a fadin line via regulator. Wannan tana daidaita small hydropower stations za su kula zuwa grid, kuma tana ci voltage qualification rate da take da amfani da ita a line, da kuma tana daidaita safe and stable operation na power grid.

3. Kasarwa

Idan an yi amfani da bidirectional automatic voltage regulation device a lines supplied by small hydropower stations, tattalin karamin kashi da tattalin karamin kashi sun nuna cewa bayar da bidirectional feeder automatic voltage regulator tana ci kyakkyawan voltage, tana halaye masu mafi karfi na voltage regulation conflict a ranar mai yaƙe da ranar mai ruwa.
