AC frequency haina hukama zvakananga neinjini yekumhanya yehydropower station, asi ine hukama zvisina kunanga.
Hazvina mhosva kuti rudzii rwemagetsi ekugadzira magetsi, zvinodikanwa kuendesa simba remagetsi kune gidhi remagetsi mushure mekugadzira simba remagetsi, kureva kuti, jenareta inoda kubatanidzwa kune grid yekugadzira magetsi.Mushure mekubatanidzwa kune gridhi, yakabatanidzwa nemagetsi emagetsi seyese, uye mafrequencies kwose kwose mumagetsi emagetsi akafanana chaizvo.Iyo yakakura grid yemagetsi, idiki iyo frequency fluctuation range uye yakanyanya kugadzikana iyo frequency iri.Zvisinei, kuwanda kwegedhi remagetsi kunongoenderana chete kana simba rinoshanda rakaenzana.Apo simba rinoshanda rinobudiswa nejenereta rakagadzirirwa rakakura kudarika simba rinoshanda rekushandiswa kwemagetsi, huwandu hwehuwandu hwemagetsi huchasimuka, uye zvinopesana.
Active power balance inyaya huru yegedhi remagetsi.Nekuti simba revashandisi rinogara richichinja, gidhi remagetsi rinofanirwa kugara richiona kubuda kwemagetsi kuburitsa uye chiyero chemutoro.Chinangwa chakakosha che hydropower station mumagetsi system ndeye frequency modulation.Ehe, iyo yakakura-hombe-chiyero hydropower yeMatatu Gorges inonyanya kushandiswa kugadzira magetsi.Kuenzaniswa nemamwe marudzi ezviteshi zvemagetsi, hydropower zviteshi zvine mabhenefiti ezvakanakira mu frequency modulation.Iyo turbine yemvura inogona kukurumidza kugadzirisa kumhanya, iyo inogona zvakare kukurumidza kugadzirisa inoshanda uye inogadzirisa kubuda kwejenereta, kuitira kuti ikurumidze kuyera gidhi mutoro, nepo simba rekupisa uye simba renyukireya rinogadzirisa kubuda kweinjini zvishoma nezvishoma.Chero bedzi chiyero chesimba rinoshanda regridhi yemagetsi yakanaka, voltage inenge yakagadzikana.Naizvozvo, zviteshi zvemagetsi ehydropower zvinopa mupiro mukuru kune frequency kugadzikana kwegedhi remagetsi.
Parizvino, zviteshi zvemagetsi zvidiki uye zvepakati nepakati muChina zviri pasi pegetsi remagetsi.Iyo gidhi yemagetsi inofanirwa kuve nekutonga pamusoro peiyo huru frequency modulation magetsi zvidyarwa, kuitira kuti ive nechokwadi chekugadzikana kwemagetsi grid frequency uye voltage.Zviri nyore:
1. Giridhi yemagetsi inosarudza kumhanya kwemota.Isu zvino tinoshandisa synchronous motors yekugadzira simba, ndiko kuti, chiyero chekuchinja chakafanana neyemagetsi emagetsi, ndiko kuti, ka50 musekondi imwe.Kune jenareta remagetsi rinopisa rine peya imwe chete yemagetsi, inotenderera 3000 revolutions paminiti.Kune jenareta re hydropower chirimwa chine n pairs emagetsi, inotenderera 3000 / N paminiti.Iyo turbine yemvura uye jenareta zvinowanzobatanidzwa pamwechete kuburikidza neimwe yakagadziriswa reshiyo yekufambisa michina, saka zvinogona kutaurwa kuti inotemerwawo neiyo magetsi grid frequency.
2. Ndeipi basa rinoitwa nemuchina wekudzora mvura?Gadzirisa kuburitsa kwejenereta, ndiko kuti, simba rinotumirwa nejenereta kune grid yemagetsi.Kazhinji, rimwe simba rinodiwa kuchengetedza jenareta kusvika pakurongeka kwayo, asi kana jenareta yabatanidzwa kune gridhi, kukurumidza kwejenereta kunotarirwa negrid frequency.Panguva ino, isu tinowanzo fungidzira kuti grid frequency inoramba isina kuchinjika.Nenzira iyi, kana simba rejenereta richipfuura simba rinodiwa kuti uchengetedze kukurumidza kwakarongwa, jenereta inotumira simba kune grid uye inotora simba pane zvinopesana.Naizvozvo, kana mota ichigadzira simba pasi pemutoro unorema, kana yangobviswa kubva pairi, kumhanya kwayo kunokurumidza kuwedzera kubva pakuyerwa kumhanya kusvika kakawanda, iyo inowanzoitika tsaona dzekubhururuka!
3. Simba rinogadzirwa nejenereta richaita kuti girafu riite, uye mashizha emagetsi emvura anowanzo shandiswa sezvikamu zvekugadzirisa maitiro nekuda kwehuwandu hwehuwandu hwekugadzirisa.
