MV SVC no ka Hoʻoponopono i nā pilikia Flickelharmonic a me Dynamic Reactive Compensation

Loaʻa i kā mākou SVC nā ʻano ʻekolu e hoʻokō i nā pono o nā ʻoihana like ʻole a me nā pūnaewele: MCR, TSC, a me TCR. Hoʻohana ka MCR type SVC i ka hoʻoulu ʻia DC ponoʻī a kaupalena i ke ʻano hana hana saturation magnetic, ʻaʻole ia e hōʻemi nui i nā harmonics i hana ʻia, akā he haʻahaʻa haʻahaʻa haʻahaʻa a me ka wikiwiki pane wikiwiki. Ma ka hoʻololi ʻana i ke kihi hoʻāla o ka thyristor i loko o ka ʻōnaehana excitation MCR, hiki ke hoʻololi ʻia ke degere saturation o ka flux magnetic i ke kumu o ka reactor control magnetic, a laila e hoʻololi i ka mana reactive mana hoʻopuka o ka reactor control magnetic.

ʻO ka MCR type SVC he hilinaʻi kiʻekiʻe loa, mālama manuahi, a me ke ola lawelawe ʻaʻole i emi iho ma mua o 20 mau makahiki. Ua hāʻawi mua ʻia nā ʻōnaehana koʻikoʻi e like me nā uwila uila uila traction power supply; Hiki i ka hana paʻa a hilinaʻi hoʻi i loko o nā wahi hana hana ʻino ʻino (e like me ka distortion waveform, ka nui amplitude fluctuation, etc.); Hiki iā ia ke hoʻohana pololei i kēlā me kēia mana o ka pae uila (6-500kV), a ua maʻalahi ke hoʻouka (e like me nā transformers maʻamau) a me ka debug; Hiki ke hoʻololi palena ʻole ʻia ka mana reactive no ka loaʻa ʻana o ka hopena uku maikaʻi loa.

Ke kiʻekiʻe-voltage TSC dynamic reactive mana uku pānaʻi i loko o ka mana nenoaiu, triggering nenoaiu, thyristor ka nānā 'ana nenoai, pulse transformer, capacitor, reactor, pale wae, etc. Ka mana nenoaiu 'ike i ka reactive mana o ka mana nenoaiu i ka manawa maoli, 'akomi hoʻoholo i ka capacitor lala e pono ke hoololi, a laila e hoʻokō i ka thyristor hui puolo hui o ka hui. ʻO ke kaʻina hana ma luna nei ua hoʻopau piha ʻia, e hōʻoiaʻiʻo ʻaʻohe hopena, piʻi, a hoʻololi paha i ka wā e hoʻololi ai i nā capacitors.

ʻO ka TCR type SVC mea maʻamau he ʻelua mau ʻāpana: TCR (thyristor controlled reactor) a me FC (filter capacitor bank). Hoʻohui ka FC kaapuni i kāna hana kānana a hiki ke hāʻawi i ka mana capacitive reactive paʻa, ʻoiai ke kaapuni TCR e hoʻololi i ka inductive reactive mana puka o ka māhele mana reactor ma o ka mana thyristor. hiki ke hoʻokō i ka uku hoʻoikaika manawa maoli o ka mana reactive. Maikaʻi no nā ukana ʻekolu ʻāpana AC arc, hiki ke hoʻemi ʻia ka fluctuations volta a me ka flicker i hana ʻia. I ka manawa like, loaʻa i ka TCR type SVC ka hana hoʻoponopono hoʻokaʻawale ʻana, hiki ke hoʻohālikelike i nā haʻahaʻa kaulike ʻole o nā kapuahi AC arc ʻekolu a me nā ukana ʻē aʻe, a hoʻopaʻa i ka ʻāpana kaʻina maikaʻi ʻole o ka mana mana i ka liʻiliʻi.
