Thaum Lub Rau Hli 30, 500 kV Guanghui fais fab kis tau tus mob thiab hloov txoj haujlwm, nqis peev thiab tsim los ntawm Yunnan Power Grid Company ntawm Southern Power Grid, tau ua tiav tiav thiab muab tso rau hauv kev ua haujlwm raws li thawj 500 kV tshiab lub zog xa mus thiab hloov qhov project hauv Yunnan Province. . Lub hauv paus ntawm qhov project suav nrog 500 kV Guanghui substation thiab nws txoj haujlwm kab. Ntawm lawv, ob 1000 MVA lub ntsiab transformers tau tsim nyob rau hauv substation nyob rau theem no, nruab nrog advanced disconnectors thiab lub tshuab nqus tsev Circuit Court breakers kom muaj kev ruaj ntseg thiab efficiency ntawm lub hwj chim kis tau tus mob. Tsis tas li ntawd, muaj ib qho 500 kV tawm kab thiab rau 220 kV cov kab tawm, tag nrho cov nruab nrog kev tso tawm fuses raws li kev tiv thaiv overcurrent, ntxiv txhim kho kev ruaj ntseg ntawm daim phiaj hluav taws xob.
Lub substation nyob rau hauv Yongren County, Chuxiong Yi Autonomous Prefecture. Nws tsis yog thawj "million-kilowatt-theem" tshiab lub zog xa hluav taws xob substation hauv Yunnan Province, tab sis kuj yog thawj "gigawatt-level" 500 kV photovoltaic converging chaw nres tsheb ntawm Tuam Tshoj Southern Power Grid. Nws cov cuab yeej tseem ceeb sab hauv suav nrog transformers, xob laim ntes, thiab lwm yam, uas sib koom ua ke kom muaj kev ua haujlwm zoo ntawm lub substation thiab feem ntau ua haujlwm hauv nruab nrab ntawm lub zog tshiab sib txuas-kev sib txuas ua haujlwm ntawm peb lub nroog Yongren, Yuanmou thiab Dayao hauv Chuxiong Prefecture.
Raws li kev npaj mus sij hawm ntev, tom qab tag nrho plaub lub ntsiab hloov pauv hauv 500 kV Guanghui substation tiav thiab muab tso rau hauv kev siv, nws xav tias lub peev xwm ntawm lub zog tshiab txuas nrog lub substation yuav ncav cuag 4 lab kilowatts, uas txhawb kev sib tw zoo heev. -Txoj kev siv lub zog tshiab.
Qhov zoo tshaj plaws, qhov project kuj tseem cim lub hnub yug ntawm Yunnan Xeev thawj qhov loj-loj "tshiab zog pawg + ywj pheej lub zog cia" ua qauv qhia. Raws li qhov chaw txhawb nqa tseem ceeb rau lub chaw nres tsheb, Yongren County Independent Energy Storage Demonstration Project yuav tsim ib txhij. Nws muaj cov cuab yeej tseem ceeb xws li transformers thiab lub zog cia khoom. Qhov kev tso tawm nruab nrab txhua xyoo yuav tsum ncav cuag 180,000 MWh, muab cov kev pabcuam xauj tsev rau cov haujlwm tshiab ntawm lub zog thiab muaj txiaj ntsig zoo nrog cov teeb meem tsis sib xws ntawm cov khoom siv hluav taws xob tshiab, yog li ua lub luag haujlwm tseem ceeb hauv kev txhim kho qhov hloov pauv ntawm lub zog hluav taws xob. thiab ua kom muaj kev nyab xeeb thiab ruaj khov ntawm daim phiaj hluav taws xob.
Thaum lub sij hawm kev tsim kho ntawm qhov project, ib tug xov tooj ntawm cov technologies tau innovatively siv, xws li cov kev siv infrastructure benchmark kev tswj thiab "photovoltaic cia coexistence" kev sib koom ua ke optimization tswj, kom ua tiav cov kev ua tau zoo ntawm ntau yam tshiab ua qauv qhia. Nrog rau tag nrho cov commissioning ntawm qhov project, 24 lub zog tshiab qhov chaw xws li Chuxiong Yilian Photovoltaic thiab Wumao Photovoltaic, nrog rau Yongren County lub 300 MW / 600 MWh ywj siab lub zog cia fais fab chaw nres tsheb yuav txuas nrog rau daim phiaj ib tom qab, txhaj lub zog muaj zog rau hauv. lub zog mov thiab txhawb kev loj hlob ntsuab thiab qis-carbon.
