I-China ingelinye lamazwe ambalwa emhlabeni asebenzisa amalahle njengomthombo wawo omkhulu wamandla. Icebile ngamalahle, amandla aphehlwa ngamanzi kanye nemithombo yamandla omoya, kodwa imithombo yayo kawoyela negesi yemvelo ilinganiselwe. Ukusatshalaliswa kwemithombo yamandla ezweni lami akulingani kakhulu. Ngokuvamile, iNyakatho yeShayina kanye nenyakatho-ntshonalanga yeChina, njengeShanxi, Inner Mongolia, iShaanxi, njll., inothile ngezinsiza zamalahle; imithombo yamandla yamanzi igxile kakhulu eYunnan, Sichuan, Tibet nakwezinye izifundazwe nezifunda eziseningizimu-ntshonalanga, ezinomehluko omkhulu wokuphakama; izinsiza zamandla omoya zisakazwa ikakhulukazi ezindaweni ezisogwini oluseningizimu-mpumalanga naseziqhingini eziseduze nasezifundeni ezisenyakatho (eNyakatho-mpumalanga, eNyakatho China, eNyakatho-ntshonalanga). Izikhungo zokulayishwa kukagesi ezweni lonke zigxile kakhulu ezizindeni zokukhiqiza zezimboni nezolimo nasezindaweni ezinabantu abaningi njenge-East China kanye ne-Pearl River Delta. Ngaphandle uma kunezizathu ezikhethekile, izitshalo ezinkulu zikagesi ngokuvamile zakhiwe ezisekelweni zamandla, okuholela ezinkingeni zokudlulisa amandla. Iphrojekthi ye-"West-to-East Power Transmission" iyindlela eyinhloko yokuthola ukudluliswa kwamandla.

Ugesi uhlukile kweminye imithombo yamandla ngokuthi awukwazi ukugcinwa ngezinga elikhulu; isizukulwane, ukudluliswa kanye nokusetshenziswa kwenzeka kanyekanye. Kumele kube nokulingana kwesikhathi sangempela phakathi kokuphehlwa kukagesi nokusetshenziswa kwawo; ukwehluleka ukugcina lebhalansi kungase kubeke engcupheni ukuphepha nokuqhubeka kokuphakelwa kukagesi. Igridi yamandla iyindawo yamandla kagesi yesistimu eyakhiwe izitshalo zikagesi, iziteshi ezincane, izintambo zokuthutha, ama-transformer okusabalalisa, izintambo zokusabalalisa kanye nabasebenzisi. Ikakhulukazi yakhiwe amanethiwekhi okudlulisa nokusabalalisa.

Zonke izisetshenziswa zokudlulisa amandla nezinguquko zixhumene ukwenza inethiwekhi yokudlulisa, futhi yonke imishini yokusabalalisa neyokuguqula ixhunywe ukwenza inethiwekhi yokusabalalisa. Inethiwekhi yokudlulisa amandla iqukethe ukudluliswa kwamandla kanye nemishini yokuguqula. Imishini yokudlulisa amandla ikakhulukazi ihlanganisa amakhondakta, izintambo eziphansi, imibhoshongo, izintambo zokuvikela umlilo, izintambo zikagesi, njll.; imishini yokuguqula amandla ihlanganisa ama-transformer, ama-reactors, ama-capacitor, ama-circuit breaker, ama-switch switching, ama-switch ahlukanisayo, izibambisi zombani, ama-voltage transformer, ama-transformer amanje, amabhasi, njll. Amathuluzi ayisisekelo, kanye nokuvikela i-relay nezinye izinto zokusebenza ukuze kuqinisekiswe amandla aphephile futhi anokwethenjelwa. ukudlulisa, ukuqapha, ukulawula kanye nezinhlelo zokuxhumana zamandla. Imishini yokuguqula igxile kakhulu eziteshini ezincane. Ukudidiyelwa kwemishini eyisisekelo kanye nempahla yesibili ehlobene kunethiwekhi yokudlulisa kubalulekile ekusebenzeni okuphephile nokuzinzile kwesistimu kagesi kanye nokuvimbela izingozi zamaketanga kanye nokunqamuka kukagesi okukhulu.

Izintambo zikagesi ezithwala ugesi zisuka ezizindeni zikagesi ziye ezikhungweni zokulayisha futhi zixhume amasistimu kagesi ahlukene zibizwa ngokuthi izintambo zokudlulisela.
Imisebenzi yezintambo zokudlulisela ihlanganisa:
(1) ''Dlulisa amandla'': Umsebenzi oyinhloko wezintambo zokudlulisa ugesi ukuthutha ugesi usuka ezikhungweni zokuphehla ugesi (njengezimboni zamandla kagesi noma iziteshi zamandla avuselelekayo) uwuyise eziteshini ezikude nakubasebenzisi. Lokhu kuqinisekisa ukuhlinzekwa kwamandla okuthembekile ukuhlangabezana nezidingo zemisebenzi yezenhlalo nezomnotho.
(2) ''Izimboni ezixhumanisa amandla kagesi neziteshi ezincane'': Izintambo zokudlulisa ugesi ezihamba phezulu zixhuma ngempumelelo izizinda zikagesi ezihlukahlukene neziteshi ezincane ukuze zakhe uhlelo lukagesi oluhlangene. Lokhu kuxhumana kusiza ukufeza ukupheleliswa kwamandla kanye nokucushwa okuphelele, ukuthuthukisa ukusebenza kahle okuphelele kanye nokuzinza kwesistimu.
(3) ''Thuthukisa ukushintshisana nokusatshalaliswa kwamandla'': Izintambo zikagesi ezihamba phezulu zingaxhuma amagridi kagesi amazinga ahlukene kagesi ukuze kubonakale ukushintshaniswa nokusabalalisa amandla phakathi kwezifunda nezinhlelo ezahlukene. Lokhu kusiza ukulinganisa ukuhlinzekwa kanye nesidingo sohlelo lwamandla futhi kuqinisekiswe ukusatshalaliswa kukagesi okunengqondo.
(4) ''Yabelana ngomthamo omkhulu kagesi'': Ngezikhathi eziphakeme kakhulu zokusetshenziswa kukagesi, izintambo zokudlulisa ugesi ezihamba phezulu zingalungisa ukusatshalaliswa kwamanje ngokuvumelana nezimo zangempela ukuze zabiwe ngempumelelo umthwalo kagesi futhi zivimbele ukugcwala ngokweqile kwezinye izintambo. Lokhu kusiza ukuqinisekisa ukusebenza okuzinzile kwesistimu yamandla nokugwema ukucisha nokungasebenzi kahle.
(5) ''Ukuthuthukisa ukuzinza nokuthembeka kwesistimu kagesi'': Ukuklanywa nokwakhiwa kwezintambo zikagesi ezihamba phezulu ngokuvamile kucabangela izici ezihlukahlukene zemvelo kanye nezimo zamaphutha ukuze kuqinisekiswe ukuzinza nokuthembeka kwesistimu kagesi. Isibonelo, ngokuhlelwa kolayini okuphusile kanye nokukhetha kwemishini, ingcuphe yokwehluleka kwesistimu ingancishiswa futhi nekhono lokuthola kabusha lesistimu lingathuthukiswa.
(6) ''Nyusa ukwabiwa okuphelele kwezinsiza zamandla'': Ngezintambo zokudlulisa ugesi ezihamba phezulu, izinsiza zikagesi zingabiwa ngokufanele phakathi kwebanga elikhulu ukuze kuzuzwe ibhalansi phakathi kokuphakelwa kukagesi kanye nokufunwa. Lokhu kusiza ukuthuthukisa ukusebenza kahle kokusetshenziswa kwemithombo yamandla futhi kukhuthaze ukuthuthukiswa komnotho esimeme.
