Kugwiritsa ntchito mafakitale kwa chipangizo cha MCR cha dynamic reactive power compensation

MCR mtundu zotakataka zotakasuka mphamvu chipukuta misozi chipangizo akhoza chimagwiritsidwa ntchito m'magawo otsatirawa.

1 Power System

1) Wamba wamba. Powonjezera MCR ndi mphamvu inayake pamaziko a banki yoyambirira ya capacitor, kuwongolera kwamphamvu komanso kosalekeza kwa mphamvu zotakataka mu substation kumakwaniritsidwa, kuchitapo kanthu pafupipafupi kwa ophwanya madera kumapewedwa, kuchuluka kwa ma capacitor kumakwera kwambiri, ndipo mphamvu chinthu kwambiri bwino.

2) Chigawo chapakati. Pakukhazikitsa chipangizo cholipirira mphamvu chopangidwa ndi mcr + fc fc mu malo ocheperako, kapena kuwonjezera MCR pamaziko a fyuluta yoyambirira ya FC kuti ipange chida cholipirira mphamvu, kuwongolera kukhazikika kwa gridi yamagetsi ndikuwonjezera mphamvu yotumizira mzere.

3) Low voteji riyakitala. Kusintha otsika-voteji riyakitala wa substation mu MCR osati ali ndi ntchito zonse za otsika-voteji riyakitala, komanso ali ndi ntchito ya zotakasika mphamvu chipukuta misozi chipangizo.

4) Line zotakasika mphamvu chipukuta misozi. Kupyolera mu chiŵerengero choyenera cha mphamvu ya capacitor ndi mphamvu ya MCR, zochita za vacuum contactor zikhoza kupewedwa, kudalirika ndi chitetezo cha zida zikhoza kusintha, ndipo moyo wautumiki wa zida ukhoza kukulitsidwa kwambiri.

5) Kulipiritsa mphamvu yogwira ntchito yogawa thiransifoma. Ukadaulo wa Tsc + mcr umatengedwa kuti upititse patsogolo kulondola kwa chipukuta misozi (0.2 kvar), kuchepetsa kwambiri kusintha kwanthawi yayitali, ndikuwonetsetsa kuti chiwongola dzanja champhamvu chamagetsi chogawa chikufika pamlingo wamphamvu kwambiri wa 0 99-1, kuzindikira zenizeni zenizeni. mphamvu kasinthidwe wosanjikiza kugawa bwino.

2 Metallurgical System

Mphero zopukutira ndi ng'anjo zamagetsi ndizomwe zimatengera mphamvu zambiri. Kugwiritsa ntchito fcr + fc fc pakulipiritsa mphamvu zosinthika kumatha kusintha kwambiri mphamvu yamagetsi, kuchepetsa kusinthasintha kwamagetsi ndi kugwedezeka, kuthetsa kuipitsidwa kwa ma harmonic, kupititsa patsogolo mphamvu yamagetsi, kukonza chitetezo chamagetsi, kuchepetsa kugwiritsa ntchito mphamvu pakupanga ma unit, ndikuwongolera zinthu. khalidwe.

3 Sitima yamagetsi yamagetsi

Sitima yamagetsi yamagetsi imakhala ndi gawo limodzi lamagetsi. Chifukwa cha kusasinthika kwa locomotive, katundu wa traction substation ali ndi mawonekedwe a gawo limodzi lamphamvu, kusinthasintha kwapang'onopang'ono komanso kusinthasintha kwakukulu. Ndizosatheka kuzindikira chipukuta misozi champhamvu kwambiri pogwiritsa ntchito njira yosavuta yolipirira. Ngati MCR yokhala ndi mphamvu yoyenera imayikidwa pamaziko a fyuluta yamagetsi yokwanira, chiwongola dzanja champhamvu champhamvu chikhoza kutheka nthawi iliyonse, kusinthasintha kwamagetsi kumatha kuchepetsedwa ndipo mtundu wamagetsi ukhoza kuwongolera.

Makhalidwe a gawo limodzi katundu wa njanji yamagetsi kumabweretsanso mavuto aakulu a mkulu zoipa zinayendera chigawo chake chapamwamba magetsi gawo lapansi, ndipo ngakhale kumabweretsa zoipa zinayendera chitetezo kanthu zomera mphamvu ndi substations. Pakuyika zosefera za mcr+fc m'malo awa ndikutengera njira yoyendetsera magawo olekanitsa molingana ndi njira ya Steinmetz, vutoli litha kuthetsedwa bwino, ndipo litha kulumikizidwa mwachindunji kumagetsi amagetsi a 110 kV kuti alipire, popanda kuyika ndalama za osinthira apakatikati, malo apansi ndi ochepa, ndipo kutayika kwa zida palokha kumatha kuchepetsedwa ndi 70%.
