Maimaituji na Kirkiro Fassara a Tsarin Karamin Zabe

Tsunanin Tsarin Kirki a Nau'in Karamin Kirki

Kirkin nau'in karamin kirki yana daidai a kan gajiminta muhimmanci. A lokacin da ba a yi aiki, kirki yana zama mafi tsaki, amma a lokacin da ake yi aiki, yana zama mafi yawa. Don haka, ana bukatar zararuruka masu ingantaccen don in tsafta kirki a cikin iyakokin da za a bayar. Wannan zararuruka suna nuna tsari a lokacin da kirki yana mafi yawa, kuma suna haifar da shi a lokacin da yana mafi tsaki. Hadi su ne abubuwan da ake amfani da su don tsarin kirki a nau'in karamin kirki:

• Transformer Mai Yawan Tsari Da Ta Yi Aiki

• Transformer Mai Yawan Tsari Ba Ta Yi Aiki

• Shunt Reactors

• Synchronous Phase Modifiers

• Shunt Capacitor

• Static VAR System (SVS)

Tsunanin kirki a cikin nau'in karamin kirki a kan ina shunt inductive element yana nufin shunt compensation. Shunt compensation yana nufin bidda: static shunt compensation da synchronous compensation. A static shunt compensation, ana amfani da shunt reactors, shunt capacitors, da static VAR systems, amma a synchronous compensation, ana amfani da synchronous phase modifiers. Abubuwan da ake amfani da su don tsarin kirki suna nuna ta hanyar karin bayanai.

Transformer Mai Yawan Tsari Ba Ta Yi Aiki: A wannan hanyar, tsarin kirki an samun tsaftace da yawan tsari na transformer. Idan kana son faɗa tsari, ya kamata a tukar da transformer daga ita. Faɗar tsari na transformer yana da shirya a yi aiki tunani.

Transformer Mai Yawan Tsari Da Ta Yi Aiki: Wannan tattalin yana amfani da ita don tsafta yawan tsari na transformer don in tsafta kirki a lokacin da transformer yana yi aiki. Dukkan transformer mai karfi suna da on-load tap changers.

Shunt Reactor: Shunt reactor shine inductive current element wanda ake fada a kan line da neutral. Yana taimakawa wajen taimaka wa inductive current daga transmission lines ko underground cables. Shunt reactors suna da mahimmanci a cikin long-distance Extra-High-Voltage (EHV) da Ultra-High-Voltage (UHV) transmission lines don reactive power control.

Shunt reactors suna fi sani a sending-end substation, receiving-end substation, da intermediate substations na long EHV da UHV lines. A long-distance transmission lines, shunt reactors suna fi sani a cikin yanayi kimanin 300 km don in tsafta kirki a intermediate points.

Shunt Capacitors: Shunt capacitors suna da capacitors wanda ake fada a kan line. Suna fi sani a receiving-end substations, distribution substations, da switching substations. Shunt capacitors suna inject reactive volt-amperes zuwa line, kuma suna da shirya a yi aiki a three-phase banks.

Synchronous Phase Modifier: Synchronous phase modifier shine synchronous motor wanda ake yi aiki ba tare da mechanical load. An fada shi a cikin load a receiving end of the line. Idan kana son faɗa excitation of the field winding, synchronous phase modifier zai iya magance ko generate reactive power. Yana taimakawa wajen taimaka wa constant voltage a duk lokaci, kuma yana taimaka wa power factor.
Static VAR Systems (SVS): Static VAR compensator yana inject ko absorb inductive VAR zuwa system idan kirki yana zama mafi yawa ko mafi tsaki a kan reference value. A static VAR compensator, ana amfani da thyristors a kan switching devices, ba tare da circuit breakers. A lissafin zaman, thyristor switching yana hakika a yi aiki saboda fast operation da ability to provide transient-free operation through switching control.
