Hapana hukama hwakananga pakati pema AC frequency nekumhanya kweinjini yechiteshi chemagetsi emvura, asi pane hukama husina kunanga.
Hazvina mhosva kuti rudzii rwemichina yekugadzira magetsi, inofanira kuendesa simba kugrid mushure mekugadzira magetsi, kureva kuti, jenareta inofanira kubatanidzwa kugrid kuti igadzire magetsi. Giridhi remagetsi rakakura, frequency fluctuation range idiki, uye frequency yakasimba. grid frequency inongoenderana chete nekuti simba remagetsi rakaenzana here. Kana simba remagetsi rinoburitswa nejenareta rakakura kupfuura simba remagetsi, frequency yese yegrid yemagetsi inowedzera. ,zvakare.
Kuenzanisa kwesimba remagetsi inyaya huru mu grid yemagetsi. Nekuti mutoro wemagetsi wevashandisi unogara uchichinja, grid yemagetsi inofanira kugara ichiona kuti simba remagetsi rinobuda uye mutoro unokwana. Kushandiswa kwakakosha kwezviteshi zvemagetsi zvemvura musystem yemagetsi ndiko kudzora ma frequency. Chinangwa chikuru chemagetsi makuru emvura kugadzira magetsi. Zvichienzaniswa nedzimwe mhando dzezviteshi zvemagetsi, zviteshi zvemagetsi zvemvura zvine zvakanakira mukudzora ma frequency. Hydro turbine inogona kugadzirisa nekukurumidza kumhanya, izvo zvinogona zvakare kugadzirisa nekukurumidza simba remagetsi rinobuda uye rinoita reactive, kuitira kuti rikurumidze kuenzanisa mutoro we grid, nepo simba rekupisa, simba renyukireya, nezvimwewo, kugadzirisa simba remagetsi einjini zvishoma nezvishoma. Chero bedzi simba remagetsi re grid rakanyatsoenzana, voltage inogadzikana. Naizvozvo, chiteshi chemagetsi chemvura chine mupiro mukuru mukugadzikana kwema frequency e grid.
Parizvino, nzvimbo zhinji dzemagetsi madiki nepakati munyika dziri pasi pegrid yemagetsi zvakananga, uye grid yemagetsi inofanirwa kuve nekutonga kwakazara pamusoro pemafekitori makuru emagetsi anochinja mafrequency kuti ive nechokwadi chekugadzikana kwemafrequency egrid yemagetsi uye voltage.
1. Giridhi remagetsi rinoona kumhanya kwemota. Iye zvino tava kushandisa mota dzinoenderana pakugadzira magetsi, zvinoreva kuti mwero wekuchinja wakaenzana newegridhi remagetsi, kureva, shanduko makumi mashanu pasekondi. Kune jenareta rinoshandiswa muchiteshi chemagetsi chinodziya chine maerekitironi maviri chete, i3000 revolutions paminiti. Kune jenareta remagetsi rine maerekitironi maviri, i3000/n revolutions paminiti. Vhiri remvura nejenareta zvinowanzobatanidzwa pamwe chete nehurongwa hwekutumira hune chiyero chakatarwa, saka zvinogona kutaurwa kuti zvinotariswawo nefrequency yegridi.
2. Basa remuchina wekugadzirisa mvura nderei? Gadzirisa simba rinobuda mujenareta, kureva simba rinotumirwa nejenareta kugrid. Kazhinji zvinoda simba rakati kuti jenareta irambe iri padanho rayo rakatarwa, asi kana jenareta yabatanidzwa kugrid, kumhanya kwejenareta kunotsanangurwa nefrequency yegrid, uye tinowanzo fungidzira kuti frequency yegrid haichinje. Nenzira iyi, kana simba rejenareta rapfuura simba rinodiwa kuchengetedza kumhanya kwakatarwa, jenareta inotumira simba kugrid, uye zvinopesana neizvi inotora simba. Naizvozvo, kana mota ichiita simba nemutoro mukuru, kana yabviswa muchitima, kumhanya kwayo kuchakurumidza kuwedzera kubva pakumhanya kwakatarwa kusvika kakawanda, uye zviri nyore kukonzera tsaona yekumhanya!
3. Simba rinogadzirwa nejenareta rinozokanganisawo frequency yegrid, uye hydroelectric unit inowanzo shandiswa se frequency-modulating unit nekuda kwehuwandu hwakakwira hwe regulation rate.
