Izvo zvinodikanwa uye mikana yekusimudzira ye smart grid yehungwaru hweyakaderera-voltage midziyo

Smart grid ndiyo yakakwana sisitimu, iyo inovhara ese maficha ekugadzira magetsi, kutapurirana, kugovera, kutumira, shanduko yemagetsi uye kushandiswa kwemagetsi.Zvinoenderana nehuwandu husina kukwana, inopfuura 80% yesimba remagetsi emagetsi system inotumirwa kune vashandisi kuburikidza nemushandisi wekugovera network uye inopedzwa pamagetsi emagetsi emagetsi.Mutengi anovhara ese maturusi uye masisitimu ekufambisa, kugovera, kutonga, kuchengetedza uye kutonga kwesimba remagetsi emagetsi kubva kune emagetsi emagetsi kumidziyo yemagetsi, kunyanya kusanganisira yakangwara yakaderera-voltage midziyo, yakangwara magetsi metres uye nehungwaru masisitimu ekuvaka.Seyakakosha magetsi emidziyo inoita basa rekutonga nekudzivirira mukupera kwemushandisi, yakaderera-voltage magetsi emidziyo inoratidzirwa nehuwandu hukuru uye hwakakura.Inowanikwa pazasi pesimba remagetsi emagetsi cheni uye chikamu chakakosha chekuvakwa kweiyo yakasimba smart grid.Naizvozvo, kuti uvake smart gidhi remagetsi, zvinodikanwa kuti uzive hungwaru hweyakaderera-voltage magetsi emagetsi kumagumo emutengi seyekona yegidhi remagetsi, uye nehungwaru hwekugovera network pamagumo emutengi inovakwa ndiyo hwaro hwakakosha. kugadzira smart power grid.Iyo inetiweki, yakazara nehungwaru uye inotapukira yakaderera-voltage midziyo yemagetsi ndiyo ichave iyo huru nzira yekusimudzira mune ramangwana.

1. Smart grid inotora chikuva chakabatana uye chiyero, chiri nyore pakuvandudza uye kushandiswa kwechizvarwa chitsva chehungwaru low-voltage midziyo.

Smart grid inoda kutorwa kwemushandisi zvakabatana uye zvakamisikidzwa zvigadzirwa, parizvino marudzi ese eautomation system, yekutarisa sisitimu, manejimendi system uye pa-line yekutarisa mudziyo wekuyera, kudzivirira, kutonga, uye mamwe mabasa mune nyowani, yakabatana, chiyero chehunyanzvi hwekutsigira system. kubatanidzwa, kubatanidzwa, uye pakupedzisira kuona kusanganiswa kweakasiyana matekinoroji ekuvandudza kuvimbika, kupfupisa iyo smart grid system Mabhenefiti akadai sekuisa uye kugadzirisa nguva.Izvi zvichaunza kurerukirwa kukuru mukuvandudza uye kushandiswa kwechizvarwa chitsva chehungwaru low-voltage midziyo.

2, smart grid yakasimba, kuzvirapa, kupindirana, optimization uye zvimwe zvinodiwa zvinosimudzira zvikuru kusimudzira uye kushandiswa kwechizvarwa chitsva cheakangwara low-voltage midziyo ine yambiro yekutanga, nekukurumidza uye yakachengeteka kupora uye kuzvirapa mabasa.

Zvinoenderana nezvinodiwa neiyo smart magetsi gidhi, senge yakasimba, kuzvirapa, kupindirana uye optimization, iyo smart magetsi system inotora network yeruzivo tekinoroji, yemazuva ano yekutaurirana tekinoroji uye yekuyera tekinoroji kuti uwane hupenyu hwehurongwa hwekutonga, kukanganisa nekukurumidza nzvimbo, nzira mbiri. kutaurirana, kutarisa kwehutano hwemagetsi uye mamwe mabasa.Iko kushandiswa kweyepasi-voltage yemagetsi chiratidzo chekutora system mune yakangwara yekuparadzira network kuti ione digitalization haigone kungoita yakakwana sampling mwero uye kunaka kwakanaka, asi zvakare kufambisa kufungidzira kwekutanga kwezviitiko uye yekutanga kunyeverwa kwekukanganisa kuburikidza nekuongororwa kwechokwadi-nguva data;Iyo yekukanganisa nzvimbo inowanikwa nekukurumidza netiweki monitor.Kukurumidza uye kwakachengeteka kudzoreredza uye kuzvirapa kweiyo yekugovera network inogona kuwanikwa nekuvakazve network, optimize network mashandiro, kupatsanura kukanganisa kana network yekugovera yatadza uye nekudzoreredza otomatiki magetsi munzvimbo isina kukanganisa, kuitira kuti zvizere kusangana nedziviriro uye kutonga zvinodiwa zvehungwaru yekuparadzira network.Naizvozvo, nekuvakwa kweiyo smart grid, kushandiswa kwechizvarwa chitsva che smart low-voltage midziyo ichawedzera uye yakawanda [3].

3. Smart grid inoisa mberi zvinodiwa zvitsva zvemidziyo yakaderera-voltage maererano nekugadzirwa kwesimba remagetsi, kuvandudza kushanda kwesimba uye kunaka.

Nekune rimwe divi, kuti uone kushandiswa kwesimba remagetsi rekugadzira uye simba repamusoro-chepamusoro uye mupata kuvandudza kushanda kwesimba uye kusimudzira simba remagetsi rekugadzira simba, pamwe chete nemotokari dzemagetsi uye zvimwe zvigadzirwa zvemagetsi zvinokurumidza kuchaja, zvinoda gadzira akakodzera masisitimu aya ane chaiwo mabasa uye kuita zvinodiwa zveakaderera-voltage magetsi emagetsi;Kune rimwe divi, zvigadziriso izvi (sezvakasiyana-siyana zvazvino midziyo, gidhi rekushandisa, simba rezvishandiso zvekupinda, zvekuchaja, nezvimwewo) zvechishandiso zvinokanganisa zvakanyanya kunaka kwemagetsi, kuitira kuti kudzvanywa kweharmonic uye kudzoreredza simba muripo. , yenguva pfupi yakawandisa overvoltage kudzvinyirirwa uye inovandudzwa simba rekugadzira masisitimu, inoshanduka uye ine simba kudzvanya overvoltage kudzvanya nemidziyo yekudzivirira, # plug uye kutamba?Kuzvarwa kwenhamba yakakura yezvido senge yakagoverwa yemagetsi mota yekuchaja chiteshi midziyo zvakare inoisa mberi zvakanyanya uye zvakakwirira zvinodikanwa kune yakaderera-voltage midziyo.Traditional low-voltage midziyo inotarisana nekuwedzera uye kuwedzera, inova mukana mutsva wekuvandudza wemidziyo yakaderera-voltage.

4. Kuvakwa kweSmart grid kunokurudzira kushandiswa kwesimba rinowanikwazve uye kutonga kwemagetsi uye kudiwa, izvo zvinosimudzirawo kuvandudzwa kwemidziyo yakaderera-voltage kune kutungamira kwenetwork.

Iko kushandiswa kwesimba rinogoneka rekugadzira simba system inotyora tsika yechinyakare yekugadzira nekushandisa uye inoumba nzira mbiri inodyidzana sevhisi system pakati pevagadziri nevatengi.Yakasiyana-siyana yedata yekuisa, kusanganisira mitengo, kubhadharisa, kugovera nguva-yemagetsi gidhi reyeye kesi chiratidzo, kuburikidza nekushandiswa kweyepamusoro manejimendi software, zvinoenderana nezvinodiwa nemushandisi nenzira yekuchinjika kugadzirisa, kusimudzira mushandisi kutora chikamu mukushanda kwegidhi remagetsi uye manejimendi, kuenzanisa kudiwa kwemagetsi mushandisi, kugona kuzadzisa kudiwa kwayo uye kupa pakati pekupa uye kudiwa, kuderedza kana kuendesa peak simba rekuda, kuderedza inopisa yekumira yemagetsi chiteshi, kuenderera mberi nekuvandudza Magetsi gidhi simba rekuchengetedza simba uye kuvandudza basa remagetsi grid kuvimbika. , kuitira kuti kuwedzere kuchengetedza zviwanikwa uye kuchengetedza kwezvakatipoteredza.Izvi hazvidi chete kuvandudza maitiro matsva ekuita manejimendi, asi zvinodawo kuve nekutaura-nzira mbiri, nzira mbiri metering, simba rekutonga uye mamwe emagetsi akaderera-voltage zvigadzirwa zvemagetsi nerutsigiro rwehurongwa, saka izvi zvinodiwa zvinosimudzirawo kukurumidza kusimudzira. yemidziyo yemagetsi yakaderera-voltage kune nzira yetiweki.
