I-CCEA idinga amaphrojekthi ukuze abe namandla okusebenza alingana nama-33% afakiwe akhiqizayo.
Ukufuna kwezokuphepha kwamandla namandla ahlanzekile kuholele ekukhuleni okukhulu kwamandla wamandla avuselelekayo eNdiya. Phakathi kwemithombo yamandla evuselelekayo, amandla elanga nangomoya yiminye imithombo yamandla aphakathi akhule kakhulu futhi kufanele ahlinzeke isinxephezelo samandla okusebenzayo (i-inertia yegridi) kanye nokuqina kwamandla kagesi ukuqinisekisa ukuphepha kwegridi.
Ingxenye yamandla elanga nanomoya osebeni elifakiwe akhuphuke cishe ku-25,5% kusukela ngoDisemba 2022 kusukela ngaphansi kuka-10% ekupheleni kuka-2013, ngokusho kukaMercom India Research.
Lapho amandla avuselelekayo ekungeneni okuningi kwegridi okuphansi, kungaxhunywa ngaphandle noma ngaphandle ngaphandle kokuthinta kakhulu ukuqina kwegridi. Kodwa-ke, njengokuhlanganiswa kwemithombo yamandla evuselelekayo kwigridi yamandla inyuka, noma yikuphi ukuphambuka kuzothinta kakhulu ukuqina nokwethenjwa kohlelo lwamandla.
Izinsizakalo zamandla asebenzayo zisetshenziselwa ukuqinisekisa ukuthi amazinga kagesi asele ngaphakathi kwemingcele ebekiwe. I-Voltage igcina ukudluliswa kwamandla okubonakalayo kusuka ku-generator kuya emthwalweni. Amandla asebenzayo azothinta i-System Voltage, ngaleyo ndlela athinte kakhulu ukuphepha kwenethiwekhi.
Uhulumeni wathatha izinyathelo kulo nyaka ngemuva kwezehlakalo ezahlukahlukene zokulahleka kwamandla asongelwa ngegridi kazwelonke.
I-Central Electricity Authority (CEA) ibike isanda kubike izehlakalo ezingama-28 zezikhathi zokuphambuka imvamisa yegridi emikhawulweni esethiwe kusukela ngoJanuwari 2022, okuholela ekulahlekelweni okungaphezu kwe-1 000 mw yamandla angaphezu kwenkulungwane. Lokhu kuphakama ukukhathazeka ngokuphuma kwamandla kagesi njalo.
Iningi lemicimbi ebikiwe lihlobene nokuguquguquka kwama-overvoltages ngesikhathi sokushintshana, ukuguquguquka okuphansi okuphansi kwemithombo yamandla evuselelekayo namaphutha eduze kwamandla wamandla avuselelekayo.
Ukuhlaziywa kwalezi zigameko kukhombisa ukuthi ukusekelwa kwamandla okusebenza okuphelele okuvela emithonjeni yamandla evuselelekayo evuselelekayo kungenye yezinto ezinomthelela kuzo zombili izimo ezishukumisayo.
Amaphrojekthi wamandla weSolar Nawomoya acishe abe ngu-63% wamandla wamandla avuselelekayo avuselelekayo, kepha aphule imfuneko ye-CCEA yokuthi i-akhawunti yamandla esebenzayo yamandla angama-33% e-Project ekhiqizayo, ikakhulukazi esifundeni esenyakatho. Kukota yesibili ka-2023 kuphela, i-India yakhiqiza amayunithi ayizigidi eziyizinkulungwane ezingama-30 wamandla elanga.
I-CCEYA selokhu yaqondisa bonke abathuthukisi bamandla abavuselelekayo abafake isicelo sokuxhumana ngo-Ephreli 30, 2023, ukuhambisana nemithetho yokuxhumana yeCEA ngoSepthemba 30 noma ukuvalwa kobuso.
Ngokusho kwemithethonqubo, ukusekelwa kwamandla aguqukayo aguqukayo kuyadingeka ngesikhathi se-voltage (LVRT) kanye ne-High Voltage Voltage Voltage (HVRT).
Lokhu kungenxa yokuthi amabhange ama-capacitor ahleliwe anganikeza kuphela ukwesekwa kwamandla okusebenzayo ngaphansi kwezimo zombuso eziqinile futhi kancane kancane anikeze ukwesekwa ngemuva kwesikhathi sokulibala. Ngakho-ke, ukuhlinzeka ngokuxhaswa kwamandla okuguqukayo okuguquguqukayo kubalulekile ukuqinisekisa ukuqina kwenethiwekhi nokuphepha.
Ukusekelwa okunamandla kuvumela amandla okusebenza kabusha okuhlinzekwa noma akhishwe ngaphakathi kwama-milliseconds ukuvimbela ukwehluleka ngesikhathi samanje / ama-voltage aphezulu.
IMercom, opharetha wohlelo lwe-Grid Controller eNdiya, atshele iMerceCom: "Esinye sezizathu zamandla kagesi aphansi, ngisho nangama-85% noma ngaphansi kwenani elilinganiselwe, ukuhluleka komoya ukuhlinzeka ukwesekwa kwamandla okusebenzayo. Isiteshi sokuhlanganisa. Amaphrojekthi elanga, njengoba ukufakwa kwemisebe yelanga kugridi kukhuphuka, umthwalo wokuhambisa imigqa main rain radies ekhuphuka, okubangela amandla okufakwayo okuhlanganisiwe / okuvuselelekayo iphuzu lokuxhumeka kwe-generator ukuze kwehle, ngisho nangaphansi kwamandla ajwayelekile angu-85%. "
"Amaphrojekthi elanga nomoya angahlangabezani nezindinganiso ze-CEA angasebenza kahle, okuphumela ekulahlekelweni kanzima kwesizukulwane. Ngokufanayo, ukuchitheka komthwalo izintambo zokusetshenziswa kungadala izimo eziphakeme zikagesi. Kulokhu, ama-generator omoya kanye nelanga ngeke akwazi ukuhlinzeka ngamandla anele. " Ukuxhaswa kwamandla okusebenzayo kubhekele ukwehla kwamandla kagesi. "
Omunye unjiniyela wamandla avuselelekayo oxoxiswane noMercom uthe ukuguquguquka nezinkinga zokuphuma kwenzeka lapho kungekho khona i-innertia inertia noma amandla asebenzayo, okukhona ezifundeni eziningi ezinikezwa amandla okuhlinzeka amandla okusebenza kabusha. Amaphrojekthi ashisayo noma we-hydropower asekelwa. Futhi uyidwebe kusuka kugridi njengoba kudingeka.
"Inkinga ivela ikakhulukazi ezifundeni ezinjengeRajasthan, lapho amandla afakiwe avuselelekayo angu-66 GW, kanye nesiGujarat, lapho kwahlelwa khona i-25-30 GW esifundeni saseKafda kuphela," kusho yena. Azikho izitshalo eziningi zamandla okushisa noma izitshalo zamandla we-hydroelectric. Izitshalo ezingagcina amandla asebenzayo ukugwema ukwehluleka kwegridi. Iningi lamaphrojekthi wamandla avuselelekayo akhiwe esikhathini esedlule awakaze akwenze lokhu, yingakho igridi eRajasthan iphuka ngezikhathi ezithile, ikakhulukazi emkhakheni wamandla ovuselelekayo. "
Uma kungekho i-inertia yegrid, amandla afudumele noma amaphrojekthi we-hydropower kumele afake isinxephezelo esiguqukayo esingahambisa amandla asebenzayo kugridi futhi akhiphe amandla okuphendula lapho kunesidingo.
Opharetha wohlelo echaza: "Amaphrojekthi wamandla avuselelekayo, isici esinamandla sika-0.95 anengqondo impela; Ama-generator atholakala esikhungweni somthwalo kufanele akwazi ukusebenza esimweni samandla esingu-0.90 agxuma endabeni ka-0.95 eholayo, kanti ama-generators atholakala eduze kwesikhungo samandla esingu-0.95 kuye nge-0.85 kuya ku-15.95 eholayo. Ukuze uthole i-generator yamandla evuselelekayo, isici samandla ka-0.95 silingana nama-33% amandla asebenzayo, anamandla okusebenza. amakhono okumele ahlinzekwe ngaphakathi kobubanzi bamandla alinganiselwe. "
Ukuxazulula le nkinga yokucindezela, abaklami bayalwa ukuthi bafake amadivaysi (aguquguqukayo e-AC Transfer System) afana nezintengiselwano ze-Static Vare noma ama-synchrous (statcom). Lawa madivaysi angashintsha okusebenzayo kwawo kwamandla okusebenzayo ngokuya ngokusebenza kwesilawuli. Basebenzisa ama-insurated Gate Bipolar Transitors (IGBTS) nezinye izilawuli ze-thyristor ukuhlinzeka ngokushintsha okusheshayo.
Ngoba imithetho ye-CCEA Wiring ayinikezi ukuqondiswa okucacile ekufakweni kwalawa madivayisi, abathuthukisi abaningi bephrojekthi abanalo ngesibopho sokuhlinzeka ngokuxhaswa kwamandla okusebenzayo futhi ngenxa yalokho sebathole izindleko zayo kwinqubo eyodwa.
Amaphrojekthi wamandla avuselelekayo avuselelekayo ngaphandle kwemishini enjalo adinga amandla okusekelayo avela kuma-inverters afakwe ohlelweni. Lokhu kuqinisekisa ukuthi noma ngabe akhiqiza amandla emthwalweni ogcwele, asenendlu yangasese ukuhlinzeka nge-lag noma ukuxhaswa kwamandla okusebenzayo ukuvikela iphuzu lokuvumelanisa le-voltable kusuka kumingcele evunyelwe edlula. Okuwukuphela kwenye indlela ukwenza isinxephezelo sangaphandle ezindaweni zokugcina zefekthri, okuyinto eshukumisayo isinxephezelo.
Kodwa-ke, noma ngabe ngamandla kuphela atholakalayo, i-inverter ingena kwimodi yokulala lapho igridi icima, ngakho-ke isinxephezelo samandla ashukumisayo noma aguquguqukayo adingekayo.
Omunye umthuthukisi wamaphrojekthi wamandla avuselelekayo uthe, "Phambilini, abathuthukisi abakaze bakhathazeke ngalezi zinto njengoba zazinqunywa kakhulu ezingeni lokufakwa esikhundleni noma kwigridi yamandla eNdiya. Ngokwanda kwamandla avuselelekayo aza kwigridi, abathuthukisi kufanele bazibekele izici ezinjalo. " Iphrojekthi ephakathi ye-100 MW, kudingeka sifake i-10 MVAR Statcom, engabiza noma kuphi kusuka ku-Rs 3 kuye ku-400 crore (cishe ama-48,2 million) bese ucubungula izindleko zephrojekthi. "
Ubuye wanezela: "Kulindelwe ukuthi lezi zidingo ezengeziwe kumaphrojekthi akhona zizobhekwa ngokuhambisana nezinguquko kwimigomo yezomthetho yokuthenga kwamandla. Lapho ikhodi yegridi ikhishwa ngonyaka we-2017, ukucatshangelwa kwanikezwa ukuthi ngabe amabhange e-catacitor ajwayelekile kufanele afakwe noma amabhange ashukumisayo eCapacitor. ama-reactors, bese i-statcom. Onke la madivayisi ayakwazi ukunxephezela isidingo samandla asebenzayo wenethiwekhi. Onjiniyela abanqikazi ukufaka amadivayisi anjalo, kepha izindleko ziyinkinga. Lezi zindleko azikaze zibhekwe phambilini eziphakanyisiwe zentela, ngakho-ke kufanele zifakwe kuhlaka lwezinguquko zomthetho, uma kungenjalo iphrojekthi izobe ingasebenzi. "
Isigungu esiphezulu sikahulumeni savuma ukuthi ukufakwa kwama-Dynamic Ready Power Support Equipment kungathinta izindleko zephrojekthi futhi ekugcineni kube nomthelela amanani entengo kagesi wesikhathi esizayo.
Uthe, "Imishini yeStatcom esetshenziselwa ukufakwa ngaphakathi kwe-CTU. Kodwa-ke, muva nje i-CEA yethule imithetho yayo yokuxhumana idinga ukuthuthukiswa kwephrojekthi ukufaka le mishini ezitshalweni zamandla. Kumaphrojekthi lapho kuphothulwe khona amanani entengo kagesi, abathuthukisi bangasondela kwiKhomishini Yamandla e-Central Power Regnolatory bathumela isicelo sokubuyekezwa kwemibandela "yokushintsha komthetho" kulezi zimo futhi ifune isinxephezelo. Ekugcineni, i-Cerc izonquma ukuthi ukuyihlinzeka yini. Ngokuqondene nesigungu sikahulumeni, sibheka ukuphepha kwenethiwekhi njengento ebaluleke kakhulu futhi sizoqinisekisa ukuthi le mishini iyatholakala ukugwema ukuphazamiseka kumanethiwekhi. "
Njengoba ukuphepha kwegridi kuyinto ebalulekile ekuphatheni amandla amandla akhulayo okuvuselela amandla, kubonakala sengathi akukho okunye ukukhetha kepha ukufaka ezinye izindleko ze-statcom zamaphrojekthi okusebenza, okungenza noma kunganciki ezinguquko ezimeni zomthetho. .
Ngokuzayo, abathuthukisi bephrojekthi kuzodingeka bathathe lezi zindleko zibe yi-akhawunti lapho bebhida. Amandla ahlanzekile azobe abiza kakhulu, kepha i-linring yesiliva ukuthi i-India ingabheka phambili ekuphathweni kohlelo lwamandla okuzinzile, okuvumela ukuhlanganiswa okusebenzayo kwamandla avuselelekayo ohlelweni.
