Karamin Haushe na Kwalba na Islanding Lockout na Inverters na Grid-Connected

Karamin Yadda A Daidaita Kirkiyar Islanding Lockout na Infašar Grid-Connected

Daidaitar kirkiyar islanding lockout na infašar grid-connected yana nufin kowane yanayi da ake yi domin yaɗuwa cikin hanyar da infašar ta zama mafi shiga da grid, amma systemin ba zama tare da shiga da grid ba. Wadannan su ne bayanan adadin da za a iya yi don kawo matsalolin:

• Bar in settings na infašar: Tabbata setting mai girman infašar don haka a tabbatar da su dace da sahuransu da kuma tashizansu masu zamani, sama da tsari na voltage, frequency, da kuma power factor.

• Bar in grid connection: Duba kabelon, plugs, da sockets wadanda ke sanya infašar da grid don haka a dubatar da shiga da ƙwarewa ba kuma kasa.

• Islanding detection device: Bar in da device na islanding detection ya dace da kuma ya samu aiki da dabara don haka a dubatar da yake iya samun dabara game da abubuwan grid. Idan akwai matsala, device ya kamata a calibrate ko a canza.

• Infašar firmware update: Bar in version na firmware na infašar. Idan an samu version mai gudanar, zaka iya canza firmware, saboda wasu bugs na firmware zai iya rage shiga da grid.

• Grid quality inspection: Bar in inganci na grid masu zamani, sama da stability na voltage, frequency, da kuma harmonic levels. Ingancin grid mai bace zai iya rage shiga da infašar ko zai iya faɗa islanding conditions.

• Contact professionals: Idan bayanan adadin ba zama tare da kawo matsaloli, yana da kyau a duba manufacturer na infašar ko professional na solar masu zamani don labarai da taimakawa.

Yana da kyau a haɗa da ita ce da ake bayyana a kan safety procedures a lokacin barazan da troubleshooting.

Alaƙar Kirkiyar Islanding Box, Ql, da Qc

An fi sani da alaƙar kirkiyar box na islanding detection da reactive inductive power (Ql) da reactive capacitive power (Qc). Bayanin a kan wuraren rayuwa suna nuna haka:

Box na islanding detection yana da muhimmiyar aiki wajen duba da kuma cut off shiga da grid idan grid ya fito ko yana da matsala. Idan grid ya fito ko yana da matsala, box na islanding ya duba wannan lafiya da kuma cuts off shiga daga infašar PV don haka a haifar da yaɗuwar shiga zuwa ƙasashen grid da suka faru, don haka a haifar da bahaushe masu lalace.

A lokacin islanding, infašar zai iya ci gaba da shiga, da Ql da Qc suna zama key parameters da box na islanding detection ke barazan. Al'adun rayuwa suna nuna haka:

• Reactive inductive power (Ql): Wannan yana nufin shiga da aka ci gaba da infašar a lokacin islanding saboda ba ake iya sharhi shiga daga grid ba. Tsarin Ql yana da shugaban infašar da kuma abubuwan load a kan ƙasashen islanded.

• Reactive capacitive power (Qc): Wannan yana nufin reactive power da aka ci gaba da kapasiti loads a kan ƙasashen islanded, musamman daga babban kapasiti loads ko transformers da suka fuskantar. Tsarin Qc yana da shugaban nature da ke kapasiti na loads ko transformers a kan ƙasashen islanded.

A cikin rayuwa, box na islanding detection zai iya barazan reactive inductive power da kuma reactive capacitive power na infašar don haka a dubatar da islanding condition da kuma trigger shutdown na infašar don haka a haifar da dalilin system.

Lura cewa design da functionality na box na islanding detection zai iya kasance da model na equipment, kuma saboda haka za a iya samun wasu special cases.
