Ukufuna ukuthi kwenziwe ngendlela ephambanayo kwezindlela zokusebenzisa umthwalo nokuphanda kwamathuba okuthi umthwalo uphanda kakhulu akuyiyo kuphela imibuzo eyadingeka ukuzihlanganisa yama-business, kodwa kuyizinkinga ezibalulekile kumkhuba wokuthi isistimu siyasebenza ngokuphelele futhi siyagcina izimpendulo zokugcinwa kwezindawo zokusebenza kwezibhizinisi nezindawo zokusebenza. Nangona izistimu zesolar photovoltaic (PV) ziyisibonelo esiphambanayo, ukuthi iziphumo zezistimu zesolar PV zingapheli ngokuphelele ngezinye izistimu zokuhlangana nemithambo yomkhakha. i-Hybrid Inverter yilungisele lokusebenzisa amandla okusho kahle, esihlanganisa ukuthenga kwesitha, ukugcina, nokuhlanganisa nendawo yamandla. Sifunda izinkulungwane zokusebenzisa amandla ngokuphelele e-WTHD, njengoko kubizwa ngamandla okusho okuhlanganisiwe, izinkulungwane zokugcina amandla, nokunye, okufundisa ukusebenzisa, ukugcina, nokuphatha amandla ngendlela entsha kubizinesi. Sibone indlela okunguqondwa ngayo ukuthenga kwesitha kusuka kuzo zonke izinkulungwane zokuthenga kwesitha kusukela ku-‘hybrid inverters’ ukuze kwenzeke ukuthenga kwesitha ngendlela efana nezinkulungwane zokuthenga kwesitha.
Ukuphakanyisa ukuthenga kwesitha ngokuphelele ngokuphatha amandla ngokuphelele
Into eyodwa yokubaluleka kwezindawo zokuthenga kwesitha zokugxila kwindawo yamandla yisikhathi: lapho isitha sishaya, sithenga amandla angaphezu kakhulu, kodwa ababizinesi bafuna amandla kusasa, emhlabathini, noma kusikhathi esingasemthethweni ngaso sonke isikhathi sesonto. Lapho kunezindawo eziningi zokuthenga kwesitha, ziyathumela kwindawo yamandla, okungaba yisikhathi sokuthumela okuncane, futhi ababizinesi bahlala bathola amandla angaphezu kakhulu kusikhathi sokuthenga kwesitha. Lokhu kuyisibizo esikhulu kwezindlela zokuthenga kwesitha (ROI).
Ama-inverter angama-hybrid akuxazulula lokhu ngokukhulisa ukusetshenziswa kwawo , iphesenti likagesi owakhiwe yilanga osetshenziswa ibhizinisi endaweni. Ama-inverter e-hybrid e-WTHD anezinhlelo zokuphatha amandla ezakhelwe ngaphakathi ezihlala zilandelela ukusebenza kwe-PV, i-SoC yebhethri, imithwalo yesayithi namanani esikhathi sangempela. Uma amandla okukhiqiza amandla elanga edlula izidingo zomthwalo osheshayo, i-inverter ye-hybrid izothumela amandla ebhange lebhethri esikhundleni sokuwabuyisela enethini. Ngakolunye uhlangothi, uma amandla elanga encipha (ngenxa yokufiphala kwamafu noma ukuwa kwelanga) noma uma kunokukhula okungazelelwe kwesidingo samandla, i-inverter isebenzisa ibhethri elisekelayo ukuze ilinganise ukulahleka kwamandla.
Ukuxhumanisa Amandla Elanga, Ukugcinwa Kwamabhethri, Nokugesi
Ngokubhekelela kwezinye, inverter eyisibini yilomkhombi wokuphatha okuphatha izinto ezintathu zokusebenza kwamandla: amapaneli we-solar PV, ukugcina kwamandla emabhankeni, nokugcina kwamandla kwe-grid. Lokhu kuphatha kufanele kube lula, kubekwe ngokushesha kanye nokuthatha isikhundla ngokushintsha noma ukungafani, ngakho-ke ukuphatha kwezinye zokuguqula kwe-voltage ne-frequency noma ukuvulwa kwemithombo.
Am-inverter ayesibini ka-WTHD ayisebenzisa ubuchwepheshe be-digital signal processing (DSP) nobuchwepheshe bokuphatha obukhona ngaphandle ukuphatha lezinye zokusebenza kwamandla ngendlela eyodwa:
Isimo se-Solar-Only: Uma ibhanki liyagcwele futhi umsebenzi wokusebenza uyincane, inverter iyathumela konke amandla kusuka kumapaneli we-PV, futhi amandla angapheleliya ayathumelwa kwi-grid (uma kuyakwenzeka futhi kuyabhekisekile kuzo amadoda).
Isimo se-Solar+Battery: Xa umphumela we-solar uyakhulu kune-msebenzi, isivinini sesikhathi sokugcina siyaphatha ngokuzimela ukuze sibeke isikhathi esihle sokugcina (C-rate) kubhanki, ngokusebenzisa ukuxhumana kwe-BMS (battery management system), ukuze sifunde isikhathi sobhanki.
Isimo se-Solar+Grid: Lapho imvelo yasolwandle ayikwanele kodwa isithelo sesithelo sasolwandle sisekwe, isimo se-Solar+Grid sibuyela ngokuzenzakalelayo kumandla we-grid futhi sifaka imvelo yasolwandle eyatholakala ukuze sifikelele indawo yokusebenza ngokuphelele, ngokuvikela ukungasebenzi kwezinye izinhlelo zokusebenza eziningi.
Isimo se-Peak-Shaving: U-inverter uyabona ngokushesha ukuthi umandla we-grid uyadinga kakhulu emahhoshini ayo amaningi wokusebenza kwe-utility companies futhi uyasebenzisa umandla wesithelo sasolwandle ukuze ushabelele, okukhula kakhulu ukuthinteka kwe-demand, okuhambisana nomkhakha omkhulu wamandla wezindawo zokusebenza zezindawo zokusebenza.
Isimo se-Backup/Islanding: Lapho kubonakala ukuthi umandla we-grid ushwele, iz-inverter ze-hybrid zika-WTHD zibuyela kusimweni se-Backup/Islanding futhi zisebenza njengomicrogrid, zinikela umandla wezinhlelo ezingcono ngasolwandle nesithelo sasolwandle kodwa zihlukana ne-grid njengokuvikela (anti-islanding protection). Isikhathi sokuguqula siyapansi kwemilisekondi engu-10, okungakwaziwa ngokujulile ngamandla wezindawo zokusebenza zezindawo zokusebenza.
Kubalulekile kulesi sikhundla kusukela ku- umandla ophinda phinde ophinda phinde , okungukuthi kufanele kubhekwe amabhatteri kusuka kwe-solar noma kwe-grid, futhi kubhekwe emuva kusuka kwe-AC side. Amahlelo ase-WTHD aqondisa amasemikondakti wezinhlayo zokusebenza esihlukene (SiC) noma i-gallium nitride (GaN) okwenzeka ukuba abe ne-98% yokuqinisa kwe-DC‑AC nokuguqula kwe-AC‑DC. Lokhu kususa umphumela wokugcina nokukhupha imisebenzi yezinkulungwane zokugcina ezikhona kusukela kwe-3‑5%, ngakho ke yonke i-kWh eyadluliselwa iyasebenza ngokuphelele.
