Mhepo Turbines Simba Curve

 

Simba remagetsi rinoumbwa nekumhanya kwemhepod sechinhu chakazvimirira (X), tiye anoshanda simba anoita seanotsamira chinja (Y) kumisikidza coordination system.Kuparadzira hurongwa hwekumhanya kwemhepo uye simba rinoshanda rakagadzirirwa curve yakakodzera, uye pakupedzisira curve inogona kuratidza hukama pakati pekumhanya kwemhepo uye simba rinoshanda rinowanikwa.Muindasitiri yemagetsi emhepo, density yemhepo ye1.225kg/m3 inoonekwa seyakajairika mweya density, saka simba rinotenderera riri pasi peyakajairwa mweya density inonzi chiyero chemagetsi curve yemhepo turbin.es.

 

Zvinoenderana neiyo curve yemagetsi, iyo mhepo simba rekushandisa coefficient yemhepo turbine pasi peakasiyana mhepo yekumhanya mazinga anogona kuverengerwa.Kuwanda kwesimba rekushandisa kwemhepo kunoreva huyero hwesimba rinotorwa neblade kusimba remhepo rinoyerera nemundege yese yeblade, inowanzoratidzwa muCp, inova chikamu chesimba rinotorwa nemhepo turbine kubva kumhepo.Zvinoenderana nedzidziso yaBaez, iyo yakanyanya simba remhepo kushandisa coefficient yemhepo turbines i0.593.Naizvozvo, kana iyo yakaverengerwa mhepo simba rekushandisa coefficient yakakura kupfuura iyo Bates muganhu, simba curve rinogona kunzi manyepo.

 

Nekuda kwenzvimbo yakaoma yekuyerera yemhepo mumhepo purazi, mamiriro emhepo anosiyana pane imwe neimwe nzvimbo, saka yakayerwa simba curve yeimwe neimwe turbine yemhepo mumhepo inopedzwa purazi inofanira kunge yakasiyana, saka inopindirana yekudzora zano zvakare yakasiyana.Nekudaro, mune inogoneka yekudzidza kana micro-saiti yekusarudza nhanho, iyo mhepo simba resource injinjini yedhizaini Institute kana mhepo turbine mugadziri kana muridzi anogona kuvimba chete nemamiriro ekupinza ndeye theoretical simba curve kana kuyerwa simba curve yakapihwa nemugadziri.Nokudaro, munyaya yenzvimbo dzakaoma, zvinokwanisika kuwana migumisiro yakasiyana kupfuura mushure mokunge mhepo yemhepo ichivakwa.

 

Kutora maawa akazara sechiyereso chekuongorora, zvingangoita kuti maawa akazara mumunda akafanana neakaverengerwa maitiro, asi maitiro echinhu chimwe chete anosiyana zvikuru.Chikonzero chikuru chemhedzisiro iyi kutsauka kukuru mukuongororwa kwezviwanikwa zvemhepo kune nzvimbo yakaoma yenzvimbo yesaiti.Nekudaro, kubva pamaonero emagetsi curve, iyo yekushanda simba curve yeimwe neimwe poindi munzvimbo ino yemunda yakasiyana.Kana curve yemagetsi ikaverengerwa zvinoenderana nendima iyi, inogona kunge yakafanana neye theoretical simba curve yakashandiswa munguva yapfuura.

Panguva imwecheteyo, curve yemagetsi haisi imwe shanduko inoshanduka nekumhanya kwemhepo, uye kuitika kwezvikamu zvakasiyana-siyana zvemhepo yemhepo kunosungirwa kukonzera kushanduka kwemagetsi emagetsi.Iyo theoretical power curve uye yakayerwa simba curve inoedza kubvisa kufurira kwemamwe mamiriro emhepo turbine, asi simba curve panguva yekushanda haigone kufuratira kushanduka kwemagetsi curve.

 

Kana iyo yakayerwa simba curve, iyo yakajairwa (theoretical) simba curve uye mamiriro ekuumbwa uye mashandisirwo emagetsi curve anogadzirwa nekushanda kweyuniti akavhiringika pamwe chete, zvinosungirwa kukonzera kuvhiringidzika mukufunga, kurasikirwa nebasa reiyo simba curve, uye panguva imwe chete, kukakavara kusingakoshi uye kupokana kuchamuka.
