Kutshanje kuye kwatsala ingqalelo ebanzi ukuba umoya kunye namandla elanga asuka eZhangjiakou athunyelwa kwiindawo zeOlimpiki zaseBusika zaseBeijing ngeProjekthi yeZhangbei VSC-HVDC, ifumana i-100% yamandla aluhlaza kuzo zonke iindawo okokuqala kwimbali yeMidlalo yeOlimpiki. .Kodwa into engaziwayo kukuba yonke inkqubo yokucwangcisa, ukwakhiwa kunye nokusebenza kweProjekthi ye-Zhangbei VSC-HVDC, enezinga eliphezulu lombane kunye nowona mthamo mkhulu wothumelo wohlobo lwayo emhlabeni, iyimfuneko kwinkxaso eyomeleleyo yamandla. iteknoloji yokulinganisa igridi.
KwiZiko lokulinganisa iGridi yeSizwe yeZiko loPhando lwaMandla oMbane waseChina (CEPRI), iteknoloji yokulinganisa i-electromagnetic transient (EMT) echaneke ngakumbi kwaye isebenzayo idlala indima ebaluleke kakhulu ekwakhiweni nasekusebenzeni kweegridi zamandla, inkxaso yoqhagamshelo lwegridi yamandla amatsha, kunye nokwakhiwa kweenkqubo ezintsha zamandla.
Ubukhulu obungazange bubonwe ngaphambili kunye nobunzima obuphezulu beegridi zamandla buvuselela itekhnoloji yokulinganisa ukugcina ukuphuculwa.
IProjekthi ye-Zhangbei VSC-HVDC yiprojekthi enkulu yokubonisa uvavanyo lwezobuchwepheshe oludibanisa igridi enobuhlobo yamandla amakhulu ahlaziyekayo, ukuhambelana kunye nokusetyenziswa okuguquguqukayo phakathi kweendlela ezininzi zamandla, kunye nokwakhiwa kweegridi zamandla e-DC.Ngokungabikho kwamava okufunda kuwo, ukuchaneka okuphezulu kokulinganisa kubaluleke kakhulu kwinkqubo yophando, uphuhliso, ugunyaziso lovavanyo, kunye noqhagamshelo lwegridi."Siqhube ngaphezulu kwe-80,000 yekhompyuter yokulinganisa phantsi kweemeko zokusebenza ezingama-5,800 zeProjekthi ye-Zhangbei VSC-HVDC kwaye senza uhlalutyo lokulinganisa olujikelezayo kunye nokuqinisekiswa kovavanyo ngokweempawu zoqhagamshelo lwegridi yeprojekthi, amalungiselelo emowudi yokusebenza, ulawulo kunye nezicwangciso zokukhusela, kunye namanyathelo okusombulula ingxaki.Ngenxa yoko, le projekthi yasebenza ngempumelelo kwaye yanikezela ngombane oluhlaza kwiiOlimpiki zaseBusika zaseBeijing, "utshilo uZhu Yiying, uMlawuli we-Digital-Analog Hybrid Simulation Research Office yeZiko lokulinganisa iGridi kaRhulumente.
Njengoko sonke sisazi, inkqubo yamandla yeyona nkqubo intsonkothileyo eyenziwe ngumntu ehlabathini kwaye isisiseko sokusebenza koluntu lwale mihla.Xa kuthelekiswa neenkqubo ezifana nohola wendlela kunye nomzila kaloliwe, igesi yendalo, ukugcinwa kwamanzi, kunye neoli, ineempawu ezifana nokuhanjiswa kwamandla ombane ngesantya sokukhanya, ibhalansi yexesha langempela kuyo yonke inkqubo ukusuka kwisizukulwana ukuya kusetyenziso, kunye nokungaphazamiseki.Ke ngoko, ifuna ukhuseleko oluphezulu kakhulu kunye nokuthembeka.Ukulinganisa akuyona nje indlela enkulu yokufunda malunga neempawu zeegridi zamandla, ukuhlalutya izikimu zokucwangcisa, ukusebenzisa izicwangciso zokulawula, kunye nokuqinisekisa ukunyanzeliswa, kodwa kunye neteknoloji engundoqo ebalulekileyo kwinkqubo yamandla.Ngokunyuka okuqhubekayo kweenkqubo zamandla ngobukhulu kunye nobunzima, iteknoloji yokulinganisa kufuneka iqhubeke nokuphucula ukuhlangabezana neemfuno zophuhliso lweenkqubo zamandla.
Iqela lophando le-CEPRI lenza uphando lwezenzululwazi kwiZiko lokulinganisa iGridi kaRhulumente.
