Kuenzanisa ESS neUPS

Mabasa uye dimension

Iyo ESS yakafanana mukuvaka kune UPS asi inosiyana mukushandiswa kwayo.Kufanana neUPS, ESS inosanganisira simba rekuchengetedza simba semabhatiri, magetsi ekushandura magetsi, semuenzaniso, inverters, uye mamwe akasiyana emagetsi uye zvidzoro.Kusiyana neUPS, zvisinei, ESS inogona kushanda pamwe chete negridi, izvo zvinoguma nekukurisa bhasikoro rehurongwa kupfuura yaizomboita UPS.Iyo ESS inokwanisa kubatirana yakabatana negridi kana mune yakamira modhi, kana zvese zviri zviviri, zvichienderana nerudzi rwesimba rekushandura system rinoshandiswa.Iyo ESS inogona kutoshanda seUPS mashandiro.Kufanana neUPS, ESS inogona kuuya muhukuru hwakasiyana kubva kudiki rekugara sisitimu iri pasi pe20 kWh yesimba kune yekushandisa yekushandisa uchishandisa akawanda-megawatt emagetsi emidziyo masisitimu ane akawanda mabhatiri racks mukati memudziyo.

Kuumbwa kwemakemikari uye kuchengeteka

Iwo akajairwa bhatiri chemistries anoshandiswa muUPS agara ari lead-asidhi kana nickel-cadmium mabhatiri.Kusiyana neUPS, BESS inoshandisa matekinoroji akadai semabhatiri e-lithium-ion kubva pakutanga nekuti mabhatiri e-lithium-ion ane zvirinani kutenderera kwekuita uye huwandu hwesimba hwepamusoro, hunogona kupa simba rakawanda mune diki tsoka yemuviri.Lithium-ion mabhatiri ane zvakare yakaderera zvakanyanya kugadzirisa zvinodiwa pane echinyakare bhatiri tekinoroji.Asi parizvino, mabhatiri e-lithium-ion ari kuwedzera kushandiswa mumashandisirwo eUPS.

Nekudaro, tsaona yakakomba muArizona muna 2019 inosanganisira ESS inoshandiswa mukushandiswa kwekushandisa yakakonzera kukuvara kwakakomba kune vakati wandei vekutanga vanopindura uye yakakwezva kutarisisa kwevatambi vakasiyana, kusanganisira vanodzora uye masangano einishuwarenzi.Kuti ive nechokwadi chekuti munda uyu uri kukura hautadziswe nezviitiko zvekuchengetedza zvinodzivirirwa, maratidziro akakodzera uye zviyero zvinoda kuvandudzwa zveESS.Kukurudzira kuvandudzwa kwezviyero zvekuchengetedza zvakakodzera uye zviyero zveESS, Dhipatimendi reMagetsi reUS (DOE) rakatanga musangano wekutanga wepagore weESS Kuchengetedzeka uye Kuvimbika muna 2015.

Mamiriro azvino eESS uye UPS zviyero

Chinangwa chemitemo yese uye zviitiko zvekusimudzira zviyero ndezvekugadzirisa zvakakwana kuchengetedzwa kweaya masisitimu.Nehurombo, zviyero zvazvino zvakagadzira kuvhiringidzika muindasitiri.

1.NFPA 855. Gwaro rinokosha rinokanganisa kuiswa kweBESS neUPS i2020 version yeNFPA 855, Standard for the Installation of Stationary Energy Storage Systems.NFPA 855 inotsanangura kuchengetedza kwesimba se "gungano remudziyo mumwe kana kupfuura unokwanisa kuchengetedza simba rekushandisa mune ramangwana kumagetsi emuno, magidhi ekushandisa, kana gidhi rutsigiro."Tsanangudzo iyi inosanganisira zvikumbiro zveUPS neESS.Pamusoro pezvo, NFPA 855 uye macode emoto zvinoda kuti maESS aongororwe uye abvumidzwe kuUL 9540. Zvisineyi, UL 1778 yagara iri tsika yechigadzirwa chekuchengetedza chiyero cheUPS.Iyo sisitimu yakaongororwa yakazvimirira kuti ienderane nezvinodiwa zvekuchengetedza uye inotsigira kuisirwa kwakachengeteka.Naizvozvo, chinodiwa cheUL 9540 chakonzera imwe nyonganiso muindasitiri iyi.

3.UL 1973. UL 1973 ndiyo chiyero chekuchengetedzwa kwebhatiri yeESS neUPS.Nekudaro, iyo UL 1973-2018 vhezheni haisanganisi yekuyedza mabhatiri e-lead-asidhi, izvo zvinonetsawo kune masisitimu eUPS anoshandisa tekinoroji yebhatiri yechinyakare senge lead-acid mabhatiri.

Summary

Parizvino, NEC (National Electrical Code) neNFPA 855 dziri kujekesa tsananguro idzi.

• Semuenzaniso, iyo 2023 vhezheni yeNFPA 855 inojekesa kuti chaiyo lead-asidhi uye nickel-cadmium mabhatiri (600 V kana pasi) akanyorwa muUL 1973.
• Pamusoro pezvo, lead-asidi bhatiri masisitimu akasimbiswa uye akamakwa zvinoenderana neUL 1778 haidi kupihwa chitupa zvinoenderana neUL 9540 kana ichishandiswa semagetsi ekuchengetedza.

Kugadzirisa dambudziko rekushaikwa kweyedzo miyero yemabhatiri e-lead-acid uye nickel-cadmium muUL 1973, Appendix H (Ongorora dzimwe nzira dzevhavha-inodzorwa kana mhepo inotungamira-asidhi kana nickel-cadmium mabhatiri) yakanyatsowedzerwa kune chinyorwa chechitatu cheUL 1973 chakaburitswa muna Kukadzi 2022.

Shanduko idzi dzinomiririra budiriro yakanaka kuitira kusiyanisa zvakachengetedzeka zvekuisa zvinodiwa zveUPS neESS.Rimwe basa rinosanganisira kuvandudza NEC Chinyorwa 480 kuti ive nani kero yekuisa zvinodiwa zvetekinoroji kunze kwelead-acid uye nickel-cadmium.Pamusoro pezvo, iyo NFPA 855 yakajairwa inoda kuvandudzwa kuti ipe kujekeswa kukuru pamirau yekudzivirira moto, kunyanya maererano neakasiyana matekinoroji anoshandiswa mumashandisirwo akamira, angave ari UPS kana ESS.

Munyori anotarisira kuti kuenderera mberi kwekuchinja kuchavandudza kuchengetedzwa kweindasitiri, zvisinei nekuti UPS yechinyakare kana ESS inoshandiswa.Sezvatinoona mhinduro dzekuchengetedza simba dzichiwanda munzira dzakakosha uye nekukurumidza, kugadzirisa kuchengetedzwa kwemukati kwezvigadzirwa kwakakosha kuvhura hunyanzvi hwekuchengetedza uye kusangana nezvinodiwa nenharaunda.
