Mafambiro eAC haana chekuita zvakananga nekumhanya kweinjini yechiteshi chemagetsi emvura, asi ane chekuita zvisina kunanga.
Hazvina mhosva kuti rudzii rwemichina yekugadzira magetsi, inofanira kuendesa simba kugrid yemagetsi mushure mekugadzira simba, kureva kuti, jenareta inofanira kubatanidzwa kugrid kuti igadzire simba. Mushure mekubatanidzwa kugrid, inosanganiswa negrid yemagetsi yese, uye ma frequency kwese kwese mugrid yemagetsi akafanana chaizvo. Giridhi yemagetsi yakakura, frequency fluctuation range idiki uye frequency inogadzikana. Zvisinei, power grid frequency inongoenderana chete nekuti simba remagetsi rakaenzana here. Kana simba remagetsi rinogadzirwa nejenareta rakakura kupfuura simba remagetsi, frequency yese yegrid yemagetsi inowedzera, uye zvinopesana.
Kuenzanisa kwesimba remagetsi inyaya huru pagrid remagetsi. Nekuti mutoro wesimba revashandisi unogara uchichinja, grid remagetsi rinofanira kugara richiona kuti simba rinobuda uye mutoro unokwana. Kushandiswa kwakakosha kwechiteshi chemagetsi emvura musystem yemagetsi ndiko kuchinja kwema frequency. Ehe, simba guru remvura reThree Gorges rinonyanya kushandiswa kugadzira simba. Kana tichienzanisa nedzimwe mhando dzezviteshi zvemagetsi, zviteshi zvemagetsi zvemvura zvine zvakanakira mukuchinja kwema frequency. Turbine yemvura inogona kugadzirisa nekukurumidza kumhanya, iyo inogona zvakare kugadzirisa nekukurumidza kubuda kwejenareta, kuitira kuti ikwanise kuyera mutoro wegrid nekukurumidza, nepo simba rekupisa nesimba renyukireya richigadzirisa kubuda kweinjini zvishoma nezvishoma. Chero bedzi simba remagetsi remagetsi regrid rakanaka, voltage yakagadzikana. Naizvozvo, zviteshi zvemagetsi zvemvura zvinobatsira zvikuru mukugadzikana kwema frequency egrid remagetsi.
Parizvino, nzvimbo zhinji dzemagetsi madiki nepakati muChina dziri pasi pegridi yemagetsi zvakananga. Giridhi yemagetsi inofanirwa kuve nekutonga kwakazara pamusoro pemapurazi makuru emagetsi ekugadzirisa mafrequency, kuitira kuti ive nechokwadi chekuti frequency yegridi yemagetsi uye voltage zvagadzikana. Zvichitaurwa zviri nyore:
1. Giridhi remagetsi rinoona kumhanya kwemota. Iye zvino tava kushandisa mota dzinoenderana pakugadzira magetsi, kureva kuti, mwero wekuchinja wakafanana newegridhi remagetsi, kureva kuti, ka50 musekondi imwe chete. Kune jenareta yemagetsi inodziya ine maerekitironi maviri chete, inotenderera 3000 revolutions paminiti. Kune jenareta yemagetsi inodziya ine maerekitironi maviri, inotenderera 3000 / N muminiti imwe chete. Turbine yemvura nejenareta zvinowanzobatanidzwa pamwe chete kuburikidza neimwe nzira yekutumira magetsi yakagadzika, saka zvinogona kutaurwa kuti zvinotsanangurwawo nefrequency yegridi remagetsi.
2. Basa remuchina wekudzora mvura nderei? Gadzirisa simba rinobuda mujenareta, kureva simba rinotumirwa nejenareta kugrid remagetsi. Kazhinji, simba rakati rinodiwa kuti jenareta irambe iine kumhanya kwayo kwakarongwa, asi kana jenareta yabatanidzwa kugrid remagetsi, kumhanya kwejenareta kunotsanangurwa nefrequency yegrid remagetsi. Panguva ino, tinowanzo fungidzira kuti frequency yegrid remagetsi inoramba isina kuchinja. Nenzira iyi, kana simba rejenareta rapfuura simba rinodiwa kuchengetedza kumhanya kwakarongwa, jenareta inotumira simba kugrid uye inotora simba zvakasiyana. Naizvozvo, kana mota ichiita simba pasi pemutoro unorema, kana yabviswa kubva kumota, kumhanya kwayo kuchakurumidza kuwedzera kubva kumhanya kwakarongwa kusvika kakawanda, izvo zvinogona kukonzera tsaona dzekubhururuka!
3. Simba rinogadzirwa nejenareta rinozokanganisawo grid frequency, uye ma hydropower units anowanzo shandiswa sema frequency modulation units nekuda kwe regulation rate yakakwira.
