Alamarar Tushen

Indonesia ta daɗe kusan 40% daga abubuwa na duniya a cikin tushen geothermal, tare da tsarin tushen geothermal na iya ƙirƙira na 23-28 GW. Amma, zuwa shekarar 2022, kawai kusan 2.3 GW ne da aka samun hanyoyi. Gwiwar ta shafi shi a gano 5,000 MW na iya ƙirƙira zuwa 2025, amma ana iya da muhimmanci da abubuwa:

1. ​Matsalolin Karkashin Kirki: Manyan tushen geothermal suna cikin yankunan masu jiki (kamar Sumatra, Java), inda yanayin kimiyya ya faruwa da dan kasa da karamin lantana. ​Reclosers na gargajiya​ suka zama da matsaloli ga kisan karkashin (3-5× kadan da kirki na gargajiya), ba su iya sauka karkashin kasa-kasa.
2. ​Yankin Yadda Ya Daɗe: Abubuwan tushen geothermal suna haɗa 275-330°C kuma suna da gaso mai daɗe (kamar H₂S), wanda ke zama da ƙarfin daɗe na 60% biliyan manyan tushen geothermal.
3. ​Matsalolin Karkashin Kirki: Reclosers na gargajiya​ suna da lokacin daɗe (<2 seconds) kuma babu tsarin daɗe na iya kan tushen geothermal "islanded operation", wanda ke zama da karkashin kasa-kasa da take daɗe $1.2M/shekara na tushen geothermal.

Wasu matsalolin ne suna buƙata da recloser solutions na gargajiya​ don in gano abubuwan tushen geothermal na gargajiya.

Don in taimakawa tushen geothermal na Indonesia da alamarar daɗe, an yi recloser system​ da inganci:

1. ​Recloser Design Mai Tsaro Da Dukkana Daɗe:
• ​Enhancement Na Muhimman Inganta: Recloser​ vacuum interrupters da silicone rubber composites suke da kyau a wuraren 150°C kuma suke da damar H₂S, wanda ke zama da tsari na ƙarfi na 2.
• ​Sealed Cooling Structure: Recloser​ an yi air cooling + phase-change material (PCM) don in kusa tsaro a wuraren >50°C, wanda ke zama da karkashin tsaro.
2. ​Adaptive Protection Logic for Reclosers:
• ​Multi-Mode Reclosing Strategy:
• Transient Faults: Recloser​ ya yi first reclose a lokacin 0.1 seconds (minimizing outages).
• Permanent Faults: Recloser​ ya yi lock out kuma ya yi microgrid interconnection for islanded operation.
• ​Fault Location Accuracy: Reclosers​ with traveling wave ranging reduce location error to ≤50 meters, cutting inspection time by 40%.
3. ​Smart Grid-Compatible Recloser Functions:
• ​Dual-Source Switching: Reclosers​ synchronize with gas turbines/energy storage, restoring power within 0.5 seconds during grid failures.
• ​Remote Monitoring: Real-time tracking of recloser​ status and environmental parameters (soil moisture, H₂S) achieves >95% warning accuracy.
4. ​Localized Deployment of Reclosers:
• ​Modular Design: Reclosers​ disassemble for transport to remote mountainous sites, reducing installation time by 50%.
• ​Joint Maintenance: PLN-partnered spare parts depots ensure <4-hour recloser​ fault response.

Abubuwan Da Ake Samu

Abubuwan da ake samu a tushen geothermal na Indonesia suna da tsari na ƙarfi a wuraren tsaro da dukkana daɗe, wanda ke zama da abubuwan karkashin kasa-kasa. Abubuwan da ake samu sun haɗa:

• Lifespan Doubling: High-temperature/corrosion-resistant designs doubled the reclosers’ operational lifespan compared to conventional units.
• Fault Outage Reduction: Adaptive multi-mode reclosing logic reduced transient fault outages by 90% via rapid 0.1-second response times.
• Inspection Efficiency: Enhanced traveling-wave fault location accuracy (≤50m) lowered grid inspection times by 40%, preventing cascading failures.
• Grid Stability: Reclosers enabled seamless islanded operation during permanent faults, boosting overall grid reliability by 80% through coordinated microgrid switching (<0.5-second restoration).
• Operational Uptime: Supported by remote monitoring (>95% warning accuracy) and localized maintenance (<4-hour response), reclosers achieved >99% uptime across volcanic zones, accelerating Indonesia’s geothermal capacity expansion.
