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 mugedhi 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. Ehe, iyo super-scale hydropower yeMatatu Gorges Chinonyanya kushandiswa kugadzira magetsi. Kuenzaniswa nedzimwe mhando dzezviteshi zvemagetsi, hydropower zviteshi zvine zvazvakanakira mune frequency regulation. Iyo hydro turbine inogona kukurumidza kugadzirisa kukurumidza, iyo inogona kukurumidza kugadzirisa iyo inoshanda uye inogadzirisa kubuda kwejenereta, kuitira kuti ikurumidze kuenzanisa iyo grid mutoro, nepo inopisa simba uye simba renyukireya, nezvimwewo, gadzirisa kubuda kweinjini maererano neKunyanya 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 pegidhi remagetsi, uye gidhi remagetsi rinofanira kuve nekutonga kwakazara pamusoro peiyo huru frequency-modulating zvidyarwa zvemagetsi, kuitira 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 kuti uchengetedze 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 grid, uye pamwe chete inotora simba. Naizvozvo, kana mota ichiburitsa 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 richaitawo kuti riite kuwanda kwegridhi, uye hydroelectric unit inowanzoshandiswa se-frequency-modulating unit nekuda kwehuwandu hwehuwandu hwekugadzirisa.
