Iko hakuna hukama hwakananga pakati peiyo AC frequency uye injini yekumhanyisa yehydropower station, asi pane hukama husina kunanga.
Hazvina mhosva kuti imhando ipi yezvigadzirwa zvemagetsi, mushure mekugadzira magetsi, inoda kuendesa magetsi kumagetsi emagetsi, kureva kuti, jenareta inoda kubatanidzwa kune gridhi kuti ibudise magetsi.Iyo yakakura iyo grid yemagetsi, idiki iyo frequency fluctuation range, uye yakanyanya kugadzikana iyo frequency iri.Iyo grid frequency inongoenderana nekuti simba rinoshanda rakaenzana.Apo simba rinoshanda rinobudiswa nejenereta rakagadzirirwa rakakura kudarika simba rinoshanda remagetsi, huwandu hwehuwandu hwemagetsi emagetsi huchawedzera.,neimwe nzira.
Active power balance inyaya huru mugetsi remagetsi.Nekuti huwandu hwemagetsi hwevashandisi huri kuramba huchichinja, gidhi remagetsi rinofanirwa kugara richiona kuburitswa kwemagetsi uye chiyero chemutoro.Kunyanya kukosha kwekushandisa hydropower zviteshi mumagetsi system ndeye frequency regulation.Chinangwa chikuru chemagetsi makuru emvura ndechekugadzira magetsi.Kuenzaniswa nedzimwe mhando dzezviteshi zvemagetsi, hydropower zviteshi zvine zvazvakanakira mune frequency regulation.Iyo hydro turbine inogona kukurumidza kugadzirisa kumhanya, iyo inogona zvakare kukurumidza kugadzirisa inoshanda uye inogadzirisa kubuda kwejenareta, kuitira kuti ikurumidze kuyera giredhi mutoro, nepo simba rekupisa, simba renyukireya, nezvimwewo, gadzirisa kubuda kweinjini zvishoma Kunyanya kunonoka.Chero bedzi simba rinoshanda regridhi rakanyatsogadzikana, iyo voltage inenge yakagadzikana.Naizvozvo, chiteshi chehydropower chine mupiro wakakura kune iyo grid frequency kugadzikana.
Parizvino, akawanda madiki uye epakati-saizi hydropower zvidyarwa munyika zviri zvakananga pasi pegiredhi remagetsi, uye gidhi remagetsi rinofanira kuve nekutonga pamusoro peiyo huru frequency-modulating magetsi zvidyarwa kuti ive nechokwadi chekugadzikana kweiyo magetsi grid frequency uye voltage.zviri nyore:
1. Giridhi yemagetsi inosarudza kumhanya kwemota.Isu ikozvino tinoshandisa synchronous motors yekugadzira simba, izvo zvinoreva kuti chiyero chekuchinja chakaenzana neiyo yemagetsi grid, kureva, 50 shanduko pasekondi.Kune jenareta rinoshandiswa mumagetsi ekupisa ane peya imwe chete yemagetsi, inotenderera 3000 paminiti.Kune jenareta remagetsi ane n pairs emaelectrodes, iri 3000/n revolutions paminiti.Ivhiri remvura uye jenareta zvinowanzobatanidzwa pamwe chete neimwe yakagadziriswa reshiyo yekufambisa michina, saka zvinogona kutaurwa kuti inotemerwawo nekuwanda kwegridi.
2. Ndeipi basa rekugadzirisa mvura?Gadzirisa kuburitsa kwejenereta, ndiko kuti, simba iro jenareta rinotumira kune grid.Zvinowanzotora huwandu hwesimba kuchengetedza jenareta pakumhanya kwayo kwakayerwa, asi kana jenareta yakabatana kune grid, kumhanya kwejenereta kunotarwa neiyo grid frequency, uye isu tinowanzo funga kuti iyo grid frequency haichinji. .Nenzira iyi, kana simba rejenereta richipfuura simba rinodiwa kuchengetedza chiyero chekukurumidza, jenereta inotumira simba kune gridhi, uye pamwe chete inotora simba.Naizvozvo, kana mota yaburitsa simba nemutoro wakakura, kana yangobviswa pachitima, kumhanya kwayo kunokurumidza kuwedzera kubva pakuyerwa kumhanya kusvika kakawanda, uye zviri nyore kukonzera tsaona yekumhanyisa!
3. Simba rinogadzirwa nejenereta richaita kuti rive nehuwandu hwemagetsi, uye chikwata chemagetsi chinowanzoshandiswa se-frequency-modulating unit nekuda kwehuwandu hwehuwandu hwekugadzirisa.
