Daga cewa wasu synchronous condensers sun fiye wajen gina rayuwar tushen karamin kashi?

Synchronous condenser (ko da ake kira synchronous compensator ko rotating VAR compensator) ita ce nau'in mota mai zurfi wanda ba ta shiga abin da take. Amma, ana amfani da shi don inganta yadda tsohon karkashin kirkiro da tasirin reactive power na gwamnatin kashi. Synchronous condensers sun fiye waɗannan dalilai don hanyar zama tsari na grid:

1. Bayyana Ta'adancin Reactive Power

• Rolin Reactive Power: A cikin gwamnatin kashi mai zurfi, reactive power (Reactive Power, Q) yana da muhimmanci don ci gaba da sauran kirkiro da inganta aiki na abubuwa. Abubuwan kashi kadan (kamar transformers, motors, da kuma lines na transmission) sun buƙata reactive power don bincike masana'antar magana, amma ba su kaɓa reactive power da suka dace.

• Aiki na Synchronous Condensers: Ta hanyar tsara irin excitation current, synchronous condenser zai iya sanya ko kula reactive power zuwa ko daga grid. Idan kirkiro na grid yana ƙara, zai iya kara excitation current ta don bayyana reactive power, kuma haka zai haɗa saukan kirkiro. Na'amna, idan kirkiro ya ƙara, zai iya ƙara excitation current ta don kula reactive power mai ƙarami, don haka ya ƙara overvoltage.

2. Inganta Tsarin Kirkiro

• Tasiri na Fluctuations na Kirkiro: Fluctuations na kirkiro a cikin gwamnatin kashi zai iya tabbatar da aiki na abubuwa, musamman wadanda suka ƙauna da kirkiro (kamar motors da abubuwan electronics). Kirkiro mai ƙarami zai iya rage abubuwa suka faru daidai ko kuma kara tattalin aiki, amma kirkiro mai ƙara zai iya rage insulation.

• Aiki na Synchronous Condensers: Ta hanyar tsara irin reactive power, synchronous condensers zai iya jagoranci da canza irin kirkiro da inganta kirkiro a kan darajinsu da ke da tsari. Wannan yana da muhimmanci a cikin lines na transmission mai tsari ko wurare da sauran takaitaccen load, inda synchronous condensers ke taimaka wajen zama tsari.

3. Inganta Transient Stability

• Transient Stability: Idan gwamnatin kashi ta samu disturbances (kamar short circuits ko generator trips), zai iya ƙara voltage collapse ko frequency fluctuations, wanda zai ƙara loss of synchronization. Gwamnati yana buƙata reserves na reactive power don goddo tsari a nan bayan waɗannan abubuwa.

• Aiki na Synchronous Condensers: Synchronous condensers suna da inertia mai yawa da aiki mai tsari na reactive power. Su zai iya bayyana reactive support a nan faults, taimakawa gwamnati a dogara zuwa tsari. Da maɗan su zai iya kara kirkiro a nan bayan fault, kuma rage voltage collapse da inganta transient stability.

4. Inganta Power Factor

• Tasiri na Low Power Factor: Low power factor yana ƙara cewa active power zai bazu a cikin gwamnati, kara line losses, da kuma kara tattalin aiki na transmission. Yana ƙara kuma ƙaramin kirkiro, wanda zai tabbatar da aiki na abubuwa.

• Aiki na Synchronous Condensers: Ta hanyar bayyanar ko kulan reactive power, synchronous condensers zai iya inganta power factor, kara buƙatar reactive power na transmission, kara line losses, da kuma kara tattalin aiki na gwamnati.

5. Cegge Harmonics da Voltage Distortion

• Tasiri na Harmonics: Nonlinear loads (kamar variable frequency drives da rectifiers) sun ƙara harmonics a cikin gwamnatin kashi, wanda ke rage distortion na waveform na kirkiro, wanda zai tabbatar da aiki na abubuwa da kuma rage masu nasarai kamar overheating da vibration.

• Aiki na Synchronous Condensers: Ba synchronous condensers ba su iya cegge harmonics na musamman, amma su taimaka wajen inganta saukan kirkiro ta hanyar bayyanar reactive power, kara tasiri na harmonics a cikin tsari na kirkiro. Su zai iya amfani da filters don inganta tsari na power.

6. Kafa Short-Circuit Capacity

• Muhimmanci na Short-Circuit Capacity: Short-circuit capacity na gwamnatin kashi na nufin maximum short-circuit current da zai iya bayyana a nan fault. Short-circuit capacity mai ƙara taimaka wajen kasa faults, rage abubuwa daga rage, da kuma inganta tsari na gwamnati.

• Aiki na Synchronous Condensers: Synchronous condensers zai iya kafa short-circuit capacity na gwamnati, musamman a cikin load centers mai tsari ko wurare da gwamnati mai karfi. Wannan yana inganta aiki na gwamnati wajen kasa faults da kuma dogara zuwa tsari a nan daɗi.

7. Fast Dynamic Response

• Buƙatar Fast Response: Ilimimin kirkiro da reactive power a cikin gwamnatin kashi zai iya ƙara a nan daɗi saboda takaitaccen load, musamman a cikin gwamnatin kashi mai zamani da distributed energy resources (kamar wind da solar power).

• Fadada Synchronous Condensers: Synchronous condensers suna da aiki mai tsari na regulation da zai iya jagoranci da canza irin kirkiro da reactive power a nan milliseconds, bayyana reactive support daɗi. Wannan yana taimaka su wajen kawo jawabi ga canza irin kirkiro da faults na daɗi.

8. Daidaito a Cikin Systems na Transmission Mai Tsari

• Abubuwan da ake magance a Cikin Transmission Mai Tsari: Lines na transmission mai tsari suna ƙara ƙaramin kirkiro da reactive power losses, musamman a nan light load conditions. Kirkiro a kan ƙarshe na line zai ƙara ƙarami, wanda zai tabbatar da tsari na power.

• Aiki na Synchronous Condensers: Ta hanyar amfani da synchronous condensers a kan ko a kan ƙarshe na lines na transmission mai tsari, zai iya inganta reactive power losses, kara kirkiro a kan ƙarshe na line, da kuma inganta tattalin aiki na transmission. Da maɗan su zai iya kara reactive power flow a cikin line, kara line losses, da kuma kara tattalin aiki na transmission.

Summary

Synchronous condensers suna da muhimmanci a cikin inganta tsari na grid ta hanyar bayyanar reactive power support, inganta tsarin kirkiro, inganta transient stability, inganta power factor, cegge harmonics, kafa short-circuit capacity, da kuma bayyana fast dynamic response. Su suna da muhimmanci a cikin gwamnatin kashi mai zamani, inda integration na renewable energy sources da takaitaccen load zai ƙara tsari na grid. Synchronous condensers suna da muhimmanci wajen inganta tsari da tattalin aiki na gwamnatin kashi.
