Nhanganyaya pfupi yekudzivirira mheni yemhepo yekugadzira magetsi masisitimu Simba reMhepo isimba rinodzokororwa uye rakachena, uye kugadzirwa kwemagetsi emhepo ndiyo sosi yemagetsi ine hukuru hwakakura-mamiriro ebudiriro nhasi. Kuti uwane simba rakawanda remhepo, iyo imwechete-yeyuniti simba remhepo turbines iri kuwedzera, uye kureba kweiyo turbine yemhepo iri kuwedzera nekuwedzera kwehubhu kureba uye dhayamita ye impeller, uye njodzi yekurova kwemheni iri zvakare. kuwedzera. Naizvozvo, kurova kwemheni kwave kukuvadza zvakanyanya njodzi dzinongoitika dzoga mumasikirwo ekushanda kwakachengeteka kwemagetsi emhepo. Mheni chinhu chakasimba chekurebesa kubuda mumhepo, izvo zvinogona kuita zvakananga kana zvisina kunanga njodzi kune zvivako zvakawanda pasi. Sechikuva chakareba uye chakabudikira pasi, maturbine emhepo anoratidzwa kumhepo yemhepo kwenguva yakareba, uye mazhinji acho ari murenje, ayo ari panjodzi yekurova kwemheni. Muchiitiko chekurova kwemheni, simba rakakura rinoburitswa nekubuda kwemheni richakonzera kukuvadzwa kwakanyanya kumablades, kutapurirana, kugadzirwa kwemagetsi uye shanduko yemidziyo uye masisitimu ekudzora eturbine yemhepo, zvichikonzera kuvharika kweyuniti, zvichikonzera kuwedzera kukuru. kurasikirwa kwehupfumi. Kudzivirirwa kwese kwemheni overvoltage mumhepo simba system Kune iyo mhepo yekugadzira magetsi system, inogona kukamurwa kuita akati wandei mazinga ekudzivirira nzvimbo kubva kunze kusvika mukati. Nzvimbo yekunze inzvimbo yeLPZ0, inova nzvimbo yakananga mheni ine njodzi huru. Kuwedzera mukati, ndiko kuderedza ngozi. Iyo LPZ0 nharaunda inonyanya kuumbwa neyakavharira layer inoumbwa neyekunze yekudzivirira mheni mudziyo, yakasimbiswa kongiri uye simbi pombi. Iyo overvoltage inonyanya kupinda mumutsara, uye michina inodzivirirwa neyekuvhiya kudzivirira mudziyo. TRS yakatevedzana yakakosha surge dziviriro mudziyo wemhepo simba system inotora overvoltage yekudzivirira chinhu chine yakanakisa nonlinear maitiro. Mumamiriro ezvinhu akajairwa, mudziviriri wekuvhiya ari munzvimbo yakakwira yekupokana, uye iyo yekudonha ikozvino inenge zero, nekudaro ichiva nechokwadi chenguva dzose magetsi emagetsi emhepo. Kana kuwedzera kwekuwedzera kunoitika muhurongwa, iyo TRS yakatevedzana yakakosha surge inodzivirira yemhepo simba system inobatidzwa ipapo mukati me nanoseconds, ichidzikamisa amplitude yekuwedzeredza mukati meiyo yakachengeteka yekushanda renji yemidziyo, uye panguva imwe chete kuendesa kuvhiya. simba muIvhu rinosunungurwa, uye ipapo, muchengeti wekudzivirira anokurumidza kuva nzvimbo yakakwirira-inopikisa, iyo isingakanganisi kushanda kwemaitiro emagetsi emhepo.
