Kushandiswa kweHV DC Cable yeSisitimu dzeSimba muMapurojekiti eSimba Rinodzokororwa

Sezvo shanduko yepasi rose yekubvisa kabhoni iri kukurumidza, kushanda zvakanaka kwemagetsi hakusati kwambova kwakakosha kupfuura izvi. Kune vatariri vekutenga nekugadzira mapurojekiti, kusarudza nzira chaiyo yemagetsi ndiyo musiyano uripo pakati pegridi yemagetsi ine purofiti yakakura uye iyo iri kukanganiswa nekurasikirwa kwemagetsi uye nguva yekugadzirisa. Pakati pekuvandudzwa kwezvivakwa izvi paneTambo yeHV DC yemagetsi.

Zvikuru sei,Waya ye75kV DCyave mhinduro yakanaka kwazvo—yakaenzanisa kugona kukuru kwekupa magetsi pamwe nemitengo inokwanisika uye yekuisa.

Mugwaro iri rakazara, tichaongorora mashandisirwo makuru etambo yemagetsi e75kV ine voltage yakakwira, basa rayo mumapurojekiti emazuva ano esimba rinogona kushandiswazve, basa rayo rakakosha muinjiniya yeindasitiri yepamusoro, uye mafambiro emakore mashanu ari kuumba remangwana remagetsi ane simba guru.

Chii chinonzi 75kV Direct Current Cable?

Kuti uwane ruzivo rwekukurumidza:AWaya yemagetsi inotenderera ye75kVimugero wemagetsi wakagadzirirwa kutumira magetsi akananga (DC) pa75,000 volts. Kusiyana netambo dzechinyakare dzinochinjana magetsi (AC), tambo dzeDC hadzina dambudziko rekuchaja magetsi, zvichiita kuti dzitumire simba guru padaro refu zvikuru pasina kurasikirwa nesimba kwakawanda.

Mabhenefiti makuru anosanganisira:

• Kurasikirwa kwegetsi remagetsi ne30% kwakaderera pakufamba kwenguva refu zvichienzaniswa neAC.

• Inoda vatungamiriri vashoma (kazhinji matanda maviri).

• Inobvumira kubatana kwegrid isina kuenderana.

• Kudzivirira kwakasimba (kazhinji XLPE yepamusoro) kunodzivirira nharaunda dzakaoma.

Mashandisirwo Akakosha Mumapurojekiti Esimba Rinodzokororwa

Kubatanidzwa kwesimba rinodzokororwa mumagetsi emagetsi enyika kunopa dambudziko rakasiyana: nzvimbo dzakanakisa dzemapurazi emhepo nemagetsi ezuva hadziwanzove pedyo nemaguta anoshandisa simba. Apa ndipo panowanikwa simba.tambo yeDC ine voltage yakakwira yekutumira simbainova chinhu chisingakoshi.

1. Kubatanidzwa kwePurazi reMhepo reMhepo pamhenderekedzo yegungwa

Maturbine emhepo ari kunze kwegungwa ari kusundirwa kure mugungwa kuti abate mhepo yakasimba uye inogara kwenguva refu. Tambo dzeAC dzechinyakare dzinorasikirwa nesimba zvakanyanya pakufamba kwenguva refu kwepasi pegungwa.Waya ye75kV DCInoshanda sewaya yakakwana yekuburitsa kunze kwenyika kune ma arrays ari pakati nepakati kusvika makuru ekunze. Inoshandisa simba kubva pachiteshi che converter chekunze kwenyika kuenda kugrid rekunze kwenyika, zvichiita kuti megawattage yepamusoro isvike kune mutengi wekupedzisira.

2. Mapurazi Makuru Emagetsi Ezuva

Mapurazi ezuva anoshandiswa zvakanyanya anowanzo tenderera zviuru zvemaeka murenje riri kure kana munzvimbo dzakaoma.Tambo yeHV DC yemagetsi, vagadziri vanogona kuvaka magrid makuru ekuunganidza magetsi eDC anoderedza kudiwa kwema inverters akawanda anodhura eAC/DC akapararira panzvimbo yese. Simba racho rinounganidzwa uye rinotumirwa zvakanaka kugrid huru, zvichiita kuti ROI yesimba rezuva iwedzere.

3. Masisitimu Ekuchengetera Simba reMabhatiri

Sezvo simba rinogona kushandiswazve richigara kwenguva pfupi, kuchengetedza mabhatiri mugrid kwakakosha. Mabhatiri anochengetedza uye anoburitsa simba remagetsi zvakananga.tambo yemagetsi e75kV ine voltage yakakwiraKubatanidza mabheteri makuru zvakananga kumagetsi emagetsi eDC kunobvisa kurasikirwa kwekushandura, zvichiwedzera kushanda zvakanaka kwenzvimbo yese yekuchengetera zvinhu.

Waya ye75kV yeMidziyo yeMaindasitiri neUinjiniya hweMagetsi

Kunze kwegrid yemagetsi, kune kudiwa kukuru kwesimba rakasimba, rine simba rakawanda muindasitiri huru uye mukugadzira zvinhu zvetekinoroji yepamusoro.

Kugadzira Kwakanyatsonaka Kwepamusoro

Muenzaniso mukuru weizvi iindasitiri yesemiconductor. Mafekitori ekugadzira semiconductor echizvarwa chinotevera (machira) anovimba nemidziyo inonyanya kushanda nesimba, yakadai semichina ye photolithography yakanyanya kusimba (EUV). Masisitimu aya makuru anoda magetsi akasimba uye asina chaanopomerwa kuti arambe akanyatsojeka padanho re nanometer.Tambo ye75kV yemidziyo yeindasitiriInowanzo shandiswa mukati mezvivakwa zve substation zvenzvimbo iyi kuti ibvise simba rayo uye igovere simba reDC rakachena zvakakwana, rine voltage yakawanda kumayuniti emagetsi emuno (PSUs) emuchina uyu unokosha.

Uinjiniya hweMagetsi Akawanda

Semunhutambo yemagetsi yakakwira yeinjiniya yemagetsi, chiyero che75kV chinowanzoshandiswa mu:

• Kuisa Magetsi muNjanji:Kupa simba remusana kune network dzezvitima zvinomhanya zvakanyanya.

• Mabasa eMigodhi:Kuisa simba mumichina mikuru yepasi pevhu inoboorera uye masisitimu ekufambisa zvinhu uko nzvimbo iri shoma uye kuderera kwemagetsi kunofanirwa kuderedzwa.

• Nzvimbo dzeData:Nzvimbo dzedata dzeHyperscale dziri kuramba dzichitarisa mativi emagetsi eDC ane voltage iri pakati nepakati kusvika yakakwira kuti dzideredze kurasikirwa kwetransformer nekuvandudza kushanda zvakanaka kwesimba remagetsi (PUE).
