Ukuhlanganisa Isizinda Samandla Kagesi Wamanzi Kugridi Yamandla Yasendaweni

Ukuhlanganisa Isizinda Samandla Kagesi Wamanzi Kugridi Yamandla Yasendaweni
Izitshalo zamandla kagesi ngamanzi ziyimithombo ebalulekile yamandla avuselelekayo, zisebenzisa amandla e-kinetic amanzi agelezayo noma awayo ukuze akhiqize ugesi. Ukuze wenze lo gesi usetshenziswe ezindlini, amabhizinisi, nasezimbonini, amandla akhiqiziwe kufanele ahlanganiswe negridi yamandla yasendaweni. Le nqubo ibandakanya izinyathelo ezimbalwa ezibalulekile zokuqinisekisa ukuphepha, ukwethembeka, nokusebenza kahle.
1. Ukukhiqiza Amandla kanye Nokuguqulwa Kwegesi
Uma amanzi egeleza ku-hydroelectric turbine, ajikelezisa ijeneretha ekhiqiza ugesi, ngokuvamile ezingeni lamandla kagesi aphakathi nendawo (isb., 10–20 kV). Kodwa-ke, i-voltage kulesi sigaba ayifanele ukudluliswa kwebanga elide noma ukusatshalaliswa okuqondile kubathengi. Ngakho-ke, ugesi uthunyelwa kuqala ku-transformer yesinyathelo-up, okwandisa i-voltage ezingeni eliphezulu (isb, 110 kV noma ngaphezulu) ukuze udlulise kahle.
2. Uxhumano Lwegridi Ngeziteshi Ezingaphansi

Ugesi onamandla amakhulu udluliselwa esiteshini esincane esiseduze, esisebenza njengokuxhumana phakathi kwesizinda samanzi kanye negridi yesifunda noma yendawo. Esiteshini esincane, i-switchgear kanye nama-relay avikelayo aqapha futhi alawule ukuhamba kukagesi. Uma isizinda samanzi sinikeza amandla kugridi yendawo, amandla kagesi angase ehliswe futhi kusetshenziswa ama-transformer ngaphambi kokungena ohlelweni lokusabalalisa.
3. Ukuvumelanisa neGridi
Ngaphambi kokuba isikhungo esiphehla ugesi ngamanzi sikwazi ukuletha amandla kugridi, okukhiphayo kufanele kuhambisane nogesi wegridi, imvamisa, kanye nesigaba. Lesi isinyathelo esibucayi, njengoba noma yikuphi ukungafani kungabangela ukungazinzi noma ukulimala ohlelweni. Ukuvumelanisa kufinyelelwa kusetshenziswa amasistimu okulawula azenzakalelayo aqapha ngokuqhubekayo igridi futhi alungise ukusebenza kwejeneretha ngokufanele.
4. Ukulinganisa Komthwalo kanye Nokuthumela
Amandla kagesi ngokuvamile asetshenziselwa ukulinganisa umthwalo ngenxa yokuguquguquka kwawo kanye nesikhathi sokuphendula ngokushesha. Ama-opharetha egridi athumela amandla kagesi wamanzi ngokwesidingo, okuwavumela ukuthi ahambisane nemithombo ehlala ngezikhathi ezithile njengomoya nelanga. Ukuxhumana kwesikhathi sangempela phakathi kwesikhungo nesikhungo sokulawula igridi kuqinisekisa ukwabelana ngomthwalo okulungile nokuzinza kwegridi.
5. Izinhlelo Zokuvikela kanye Nokuqapha
Ukuze uvimbele amaphutha noma ukwehluleka, kokubili isitshalo kanye negridi kufakwe izinhlelo ezithuthukisiwe zokuqapha nokuvikela. Lokhu kufaka phakathi ama-circuit breaker, ama-voltage regulators, kanye nezinhlelo ze-SCADA (Supervisory Control and Data Acquisition). Uma kwenzeka iphutha, lezi zinhlelo zingahlukanisa izingxenye ezithintekile futhi zivikele ukwehluleka kwe-cascading.

Isiphetho
Ukuhlanganisa isikhungo sokuphehla ugesi ngamanzi kugridi yendawo kuyinqubo eyinkimbinkimbi kodwa ebalulekile yokuletha amandla ahlanzekile emiphakathini. Ngokuphatha ngokucophelela amazinga kagesi, ukuvumelanisa, kanye nokuvikelwa kwesistimu, izitshalo zikagesi ngamanzi zingadlala indima ethembekile neqhubekayo ekuxubeni kwamandla wesimanje.
