Sisitimu Yekutumira Nekugovera Simba reMagetsi
Muhupenyu hwedu hwezuva nezuva, simba remagetsi rinoita basa guru, richipa simba kune zvese zvinoitika muhupenyu hwemazuva ano. Zvisinei, vashoma vanonzwisisa kuti magetsi anosvika sei kudzimba, kumahofisi, nemafekitori. Ngatinyatsoongororai masisitimu emagetsi ekufambisa nekuparadzira simba, ayo ari musimboti wesimba iri.
1. Nhanganyaya kuMasisitimu eMagetsi
Sisitimu yekutumira nekuparadzira simba remagetsi inetwork yakakura ine zvikamu zvakasiyana-siyana zvinoshanda pamwe chete kuendesa magetsi kubva kunzvimbo dzinogadzira magetsi kusvika kune vatengi vekupedzisira. Maitiro aya anogona kukamurwa kuita zvikamu zvikuru zvitatu: kugadzira simba, kutumira, uye kugovera.
a. Kugadzira Magetsi
Kugadzirwa kwemagetsi ndicho chikamu chekutanga muhurongwa uhwu. Magetsi anogadzirwa muzviteshi zvemagetsi zvakasiyana-siyana, zvinosanganisira zviteshi zvemagetsi zvinopfuta mhepo, zviteshi zvemagetsi zvinobuda mumvura, zviteshi zvemagetsi zvine simba renyukireya, uye zviteshi zvemagetsi zvinodzokororwa zvakaita semhepo nesimba rezuva. Muchikamu chino, simba remagetsi rinoshandurwa kuita simba remagetsi uye rinogadzirwa pamagetsi chaiwo, kazhinji pakati pe11 kV ne25 kV.
2. Sisitimu Yekutumira Simba reMagetsi
Mushure mekunge magetsi agadzirwa, danho rinotevera nderekutumira magetsi. Masisitimu ekutumira magetsi akagadzirwa kuti atakure magetsi akawanda kubva kumafekitori anogadzira magetsi kuenda kunzvimbo dzekuisa magetsi dziri kure nenzvimbo dzinogadzira magetsi.
a. Zvikonzero zvekushandisa High Voltage
Kana magetsi achifambiswa kure, magetsi akawandisa anoshandiswa, kazhinji ari pakati pe110 kV ne765 kV. Kushandiswa kwemagetsi akawandisa kunoderedza kurasikirwa kwemagetsi panguva yekufambiswa kwemagetsi. Kurasikirwa kwemagetsi (P_loss) mutambo yekufambiswa kwemagetsi kunoenderana nemagetsi (I) uye resistance (R): P_loss = I²R. Nekuwedzera voltage (V), magetsi (I) anogona kuderedzwa nesimba rimwe chete, izvo zvinoderedza kurasikirwa kwemagetsi.
b. Zvikamu zveSisitimu yeKutumira
1. Nzvimbo yemagetsi: Nzvimbo yemagetsi kana nzvimbo yemagetsi inoshandiswa kuwedzera simba remagetsi rinogadzirwa nejenareta kuitira kuti rikwanise kutumirwa kure ne transformer inokwira ne step-up.
2. Mutsetse wekutumira: Mutsetse wekutumira inzira inoshandiswa kufambisa magetsi ane simba rakawanda kubva pachiteshi chikuru kuenda kuchiteshi chinogovera magetsi.
3. Nhare dzeTransmission: Nhare dzetransmission zvivakwa zvinotsigira tambo dzetransmission dziri pamusoro pevhu kuitira kuti system yacho ive yakachengeteka uye yakavimbika.
4. Transformer Inodzika Netsoka: Kana magetsi asvika panzvimbo inotakurika, voltage inodzikiswa kuburikidza netransformer inodzika netsoka kuti igoverwe kune network yekugovera.
3. Sisitimu Yekugovera Simba reMagetsi
Mushure mekupfuudzwa kwemagetsi, magetsi anopinda muchikamu chekugoverwa kwemagetsi icho chinopa simba kuvatengi vemagetsi vakaita sedzimba, mahofisi nemaindasitiri.
a. Zvikamu zveSisitimu Yekugovera
1. Nzvimbo yekuparadzira magetsi: Pano, magetsi anobva pamagetsi emagetsi ane simba repamusoro anoshandurwa kuita magetsi ari pakati nepakati, ari pakati pe11 kV ne33 kV.
2. Mutsetse Mukuru: Mutsetse mukuru ndiwo mutsetse unotakura magetsi ane voltage yepakati kubva pachiteshi chekugovera kuenda kutransformer yekugovera.
3. Transformer Inogovera: Transformer iyi inoshanda kuderedza voltage kubva pamutsetse wekutanga (11 kV kusvika 33 kV) kuenda kune voltage yakaderera (220V kusvika 240V) yakakodzera vatengi.
4. Mutsetse Wechipiri: Uyu ndiwo mutsetse unogovera magetsi ane simba shoma kubva kutransformer inogovera magetsi kuenda kune vatengi.
5. Distribution Panel neMCB: Muimba yega yega kana chivakwa, magetsi anopinda nepadivi rekugovera rine Miniature Circuit Breaker (MCB) kudzivirira sisitimu kubva pakuzara kwemagetsi uye mashort circuits.
b. Mhando dzeNetwork dzeKugovera
1. Radial Network: Network iyi ine simba rimwe chete rinoyerera richienda kune vatengi nenzira imwe chete. Inowanzo shandiswa munzvimbo dzemaguta dzine mutoro wakaderera.
2. Ring Network: Mune network iyi, simba rinobuda rakakomberedzwa netambo yeringi kana yedenderedzwa, zvichiita kuti simba rirambe richishandiswa kana paine dambudziko pane imwe nguva.
3. Network yekubatanidza: Network iyi isanganiswa ye ring ne radial networks uye inoshandiswa kuona kuti simba rakawanda rinoparadzirwa uye kuti zvinhu zviri nani.
4. Matambudziko neMhinduro muMasisitimu eKutumira neKugovera
Zvisinei, pasinei nekugadzirwa kwacho nenzira yakadaro, sisitimu yekufambisa nekuparadzira simba remagetsi ichiri kutarisana nematambudziko akasiyana-siyana akakomba.
a. Kurasikirwa Kwekutapurirana Nekugovera
Kunyangwe magetsi akawandisa achishandiswa kuderedza kurasikirwa, mamwe magetsi anoramba achiitika panguva yekutumirwa nekuparidzirwa. Mhinduro dzekugadzirisa izvi dzinosanganisira kugadziriswa kwemitsetse nemidziyo nguva dzose, kushandiswa kwezvinhu zvemhando yepamusoro, uye kushandiswa kwetekinoroji yepamusoro senge Superconducting Electricity Pipelines.
b. Kukanganiswa Kwemasisitimu Uye Kukundikana
Kukanganiswa kwakadai semvura inonaya zvakanyanya, mhepo ine simba, uye mheni zvinogona kukanganisa zvivakwa zvekutumira nekuparadzira. Kuderedza izvi, michina yekudzivirira yakaita serelay nemabreaker inoiswa panzvimbo dzakasiyana-siyana kuti ive nechokwadi chekuti zvinhu zviri kure uye kuti zvinokurumidza kupindura kune zvinokanganisa.
c. Kutarisira Mutoro
Kusawirirana pakati pekugadzirwa kwemagetsi nekushandiswa kwawo kunogona kukonzera matambudziko emagetsi, kusanganisira kudzimwa kwemagetsi. Smart Grid ndeimwe yemhinduro dzichangoburwa dzinoshandisa tekinoroji yeruzivo kutarisa nekudzora grid munguva chaiyo, zvichiita kuti pave nekushanda nesimba uye kugadzikana.
5. Remangwana reKutumira neKugovera Simba reMagetsi
Nekuwedzera kwekuda kwemagetsi uye kusimbiswa kwekugadzirwa kwesimba rinogona kushandiswazve, masisitimu ekutumira magetsi nekuparadzira magetsi anofanira kuramba achichinja. Kuvandudzwa kwetekinoroji dzakadai seHVDC (High Voltage Direct Current) yekutumira magetsi kure, kushandiswa kweIoT nebig data mukutarisira network, uye kubatanidzwa kwesimba rinogona kushandiswazve mugrid ndiyo nzvimbo huru dzekutarisisa mukuvandudzwa kwemasisitimu aya mune ramangwana.
Mhedziso
Masisitimu ekufambisa nekuparadzira simba remagetsi zvinhu zvakakosha mukuona kuti simba rinogadzirwa nemagetsi rinosvika kune vatengi zvakachengeteka uye zvinobudirira. Pasinei nekutarisana nematambudziko akasiyana-siyana, hunyanzvi hwakasiyana-siyana hwetekinoroji huri kuramba huchigadzirwa kuti huvandudze kushanda zvakanaka uye kuvimbika kwemasisitimu aya. Nekunzwisisa zviri nani mashandiro anoita masisitimu aya nezvikamu zvawo, tinogona kunzwisisa zviri nani basa rawo rinokosha mukutsigira hupenyu hwedu hwezuva nezuva.
