Kutarisisa kwesimba rekupa system: magetsi grid, substation

Iyo grid yekubatanidza mapurojekiti emagetsi emhepo eKazakhstan akaiswa mari nemakambani eChinese anorerutsa kudzvanywa kwemagetsi kumaodzanyemba kweKazakhstan.

Simba remagetsi rine zvakanakira kutendeuka kuri nyore, kutapurirana kwehupfumi, uye kutonga kuri nyore.Naizvozvo, munguva yanhasi, ingave kugadzirwa kwemaindasitiri nekurima kana kuvaka kwedziviriro yenyika kana kunyange muhupenyu hwezuva nezuva, magetsi akawedzera kupinda munzvimbo dzese dzemabasa evanhu.Magetsi ekugadzira anogadzirwa nemagetsi emagetsi, uye simba remagetsi rinoda kukwidziridzwa nedanho-up substation kusvika kune yakakwira voltage yemazana akati wandei kilovolts (senge 110 ~ 200kv), inotakurwa neakakwira-voltage transmission tambo kune simba- nzvimbo yekudyira, uye yozogovaniswa neiyo substation.kumushandisi wega wega.

Iyo magetsi sisitimu izere rekugadzira magetsi, kugovera uye kushandiswa kunoumbwa nemagetsi zvidyarwa, substation transmisheni mitsetse, kugovera network uye vashandisi.

Giridhi yemagetsi: Giridhi yemagetsi inobatanidza pakati pezvidyarwa zvemagetsi nevashandisi, uye mudziyo unofambisa nekugovera simba remagetsi.Iyo magetsi network ine mitsara yekuparadzira uye yekuparadzira uye substations ine akasiyana voltage mazinga, uye inowanzo patsanurwa kuita zvikamu zviviri: transmission network uye network yekugovera zvinoenderana nemabasa avo.Iyo network yekutumira inoumbwa nemitsara yekufambisa ye35kV uye pamusoro uye zviteshi zvakabatanidzwa kwairi.Ndiyo huru network yemagetsi system.Basa rayo ndere kuendesa simba remagetsi kune network yekugovera mumatunhu akasiyana kana zvakananga kune makuru mabhizinesi vashandisi.Iyo network yekugovera inoumbwa nemitsara yekugovera uye kugovera kushandura kwe10kV uye pasi, uye basa rayo ndere kuendesa simba remagetsi kune vakasiyana-siyana.

Substation: Chiteshi inzvimbo yekugamuchira uye kugovera simba remagetsi uye shanduko yemagetsi, uye ndeimwe yehukama hwakakosha pakati pezvidyarwa zvemagetsi nevashandisi.Iyo substation inoumbwa nemagetsi emagetsi, emukati uye ekunze magetsi ekuparadzira zvishandiso, relay kuchengetedza, dhizaini michina uye yekutarisa masisitimu.Shandura ese mapoinzi enhanho-kumusoro uye nhanho-pasi.Iyo nhanho-up substation inowanzobatanidzwa nehombe simba chirimwa.A nhanho-up transformer inoiswa muchikamu chemagetsi chemagetsi emagetsi kuti awedzere mhepo yemagetsi emagetsi uye kutumira simba remagetsi kure kure kuburikidza ne-high-voltage transmission network.Iyo nhanho-pasi substation Inowanikwa munzvimbo yekushandisa magetsi, uye yakakwira voltage inoderedzwa zvakakodzera kupa simba kune vashandisi munzvimbo.Nekuda kwehukuru hwakasiyana hwekugovera magetsi, zviteshi zvinogona kukamurwa kuita zvepuraimari (hub) zviteshi uye zvechipiri zviteshi.Zviteshi zvemafekitori nemabhizinesi zvinogona kukamurwa kuita zviteshi zvekudzika-pasi (pakati pezviteshi) nezviteshi zvewekishopu.
Nzvimbo yewekishopu inogamuchira simba kubva ku6 ~ 10kV yakakwira-voltage yekuparadzira tambo munzvimbo yechirimwa inotorwa kubva padanho-pasi substation, uye inoderedza voltage kune yakaderera-voltage 380/220v kuti ipe zvakananga magetsi kune ese emagetsi midziyo.
