Mfundo yogwirira ntchito ya 2021 yotentha ndi ng’anjo yatsopano

1. Kuchokera pa chithunzi cha dera lalikulu la chowotcha kutentha Pamwambapa, zitha kuwoneka kuti gawo lamagetsi lamoto losungunuka limapangidwa ndi cholumikizira magetsi ndi kuyamwa kwa magawo atatu a AC; gawo lokonzanso limapangidwa ndi mlatho wokhala ndi magawo atatu oyendetsedwa bwino wopangidwa ndi ma thyristors angapo, Amathandizira kuti mphamvu yotulutsa ng’anjo isungunuke mosalekeza kuchokera ku 0.1Pn (Pn imayimira mphamvu yomwe idavoteledwa) kupita ku Pn. Ikatsekedwa kapena ikalephera ndikusiya kuyendetsa, wokonzanso amatha kutembenuzidwa kuchokera ku malo ogwirira ntchito kupita kumalo ogwirira ntchito, kotero kuti amasungidwa mu DC Mphamvu mu dera lapakatikati imabwereranso ku netiweki yamagetsi. Pofuna kuteteza rectifier thyristor, fuse fuse ndi DC zotchinjiriza chitetezo chazomwe zimayikidwanso.

Dongosolo lapakati la DC limakhala lopangidwa ndimadzi otentha ndi chitsulo. Ntchito yake ndikosefera kutulutsa kwa DC komwe kumakonzanso ndi kupondereza mphamvu yamagetsi yapakati pama gridi amagetsi. Katunduyu akatulutsidwa mozungulira, umathandizanso kuti mphepo isakwere kwambiri.

Inverter imapangidwa ndi gawo limodzi lokhala ndi gawo limodzi lokhalanso ndi olamulira ambiri othamanga. Mwa kusinthitsa ma thyristors, zomwe zikuchitika tsopano zimachokera kumalo omaliza a u ndi v a katundu wofananira motsatana mosinthasintha pafupipafupi.

Kuphatikiza apo, dera lalikulu lazitsulo losungunuka lamoto limaphatikizaponso ma circuits a AC ndi DC.

2. Dera lolamulira

Dera lomwe lili pachithunzi chachikulu cha dera ndilo kayendetsedwe kazitsulo kotentha kotentha. Pachigawo chino, chithunzi chowongolera mwatsatanetsatane chimaperekedwa. Zitha kuwonedwa kuchokera pachimake kuti kukonzanso kwa ng’anjo yosungunuka kumayendetsedwa ndi magawo awiri: wowongolera wowongolera komanso choyambitsa chowongolera. Variable zimachitika mkuzamawu kulamulira.

Kuwunika kolakwika ndi chitetezo cha ng’anjo yonse yosungunuka kumayang’aniridwa ndi chitetezo chamagetsi ndi kuwunika kwa inverter, ndipo zizindikiritso zamagetsi zamakono ndi zamagetsi zimamalizidwa makamaka ndi komiti yolandirira mayankho.

Kuyamba kwa ng’anjo yonse yosungunuka kumamalizidwa ndi kuwongolera kwakanthawi.

Kuphatikiza kwa mayunitsi onse pamwambapa kumayang’aniridwa ndi wowongolera (PLC).
