imibuzo ejwayelekile ukubuzwa
Q: Yini isiqukathi se-PCS ku-BESS?
A: Isiqukathi se-PCS siyisistimu yokuguqula amandla esiqukathi phakathi kweziqukathi zebhethri kanye negridi ye-voltage emaphakathi-. Iguqula izingxenye ezimbili ze-DC/AC futhi ingahlanganisa{2}}i-transformer eya phezulu, i-MV switchgear, ukuvikela, ukupholisa kanye nokuxhumana ibe ibhulokhi yamandla eyodwa.
Q: Ingabe isitsha se-PCS sihlanganisa i-transformer?
A: Yebo. Iziqukathi ze-Polinovel BESS PCS zihlanganisa isinyathelo{1}}siguquli esikhuphukayo ukuze sikhuphule ukuphuma kwe-PCS okuphansi-ku-voltage AC kuya ku-voltage emaphakathi ukuze kuxhunywe igridi. Uhlobo lwe-Transformer, umthamo kanye nokuphumayo kwe-MV kuyalungiswa ngephrojekthi ngayinye.
Q: Uyini umehluko phakathi kwesiqukathi se-PCS nesiqukathi sebhethri?
A: Isiqukathi sebhethri sigcina amandla kanye nemiphumela ye-DC; isiqukathi se-PCS siguqula leyo DC ibe yigridi ye-AC, siyinyuse ifike kuvoltheji emaphakathi futhi ilawule ukuxhumana kwegridi. Zingamayunithi ahambisanayo esitshalweni esisodwa.
Q: Uyini umehluko phakathi kwe-centralized kanye ne-string PCS?
A: I-PCS ephakathi nendawo iguqula amandla amaqoqo amaningi ebhethri ndawonye ukuze kube ibhulokhi yamandla ehlangene, esezingeni. I-PCS yochungechunge isebenzisa amayunithi e-modular ekulawuleni iqoqo elicolekileyo{1}}kanye nokuhlukaniswa kwamaphutha kwasendaweni.
Q: Ingabe i-voltage ephumayo ye-MV ingenziwa ngezifiso?
A: Yebo. Okukhiphayo-i-voltage emaphakathi ihlanganisa ububanzi buka-10kV kuya ku-35kV futhi ilungiselelwa ikhodi yegridi yasendaweni nephrojekthi, kusetshenziswa{4}}uhlobo olomile noma uwoyela{5}}ocwilisiwe{6}}i-transformer ephezulu.
Q: Amandla e-PCS kufanele afaniswe kanjani nomthamo webhethri?
A: Amandla alinganiselwe e-PCS akhethwa ngokumelene nethagethi yamandla eplanti, umthamo wamandla ebhethri kanye -nesilinganiso esingu-C, iwindi le-voltage ye-DC, inani leziqukathi zebhethri kanye negridi edingekayo-yokwenza noma igridi{2}}imisebenzi elandelayo.
