Project Background
Indonesia is situated within the Pacific Ring of Fire, experiencing frequent seismic activity, with thousands of earthquakes annually, including a high proportion of magnitude 7+ events. Earthquakes threaten public safety and severely damage power infrastructure. Traditional Air-Insulated Switchgear (AIS) has limited seismic resistance, often suffering insulation failure or equipment damage during earthquakes. High Voltage Gas-Insulated Switchgear (HV GIS) technology, however, offers superior resilience due to its compact, gas-insulated design, making it critical for Indonesia’s grid modernization.
Under the "Belt and Road" framework, collaborative projects like the 2019 Chengdu-based Institute of Care-Life (ICL) early warning system have provided seismic data to optimize High Voltage Gas-Insulated Switchgear (HV GIS) deployment. Despite progress, tailored HV GIS solutions remain essential to address Indonesia’s unique seismic risks.
Solution
To address Indonesia’s challenges, the following High Voltage Gas-Insulated Switchgear (HV GIS) solutions are proposed:
Equipment Selection and Seismic Design
o Use 72.5kV–252kV fully enclosed High Voltage Gas-Insulated Switchgear (HV GIS) with SF6 insulation, achieving Intensity 9 seismic resistance (0.3g horizontal/0.15g vertical acceleration).
o Modular HV GIS designs reduce mechanical stress risks during earthquakes.
Smart Monitoring and Early Warning Integration
o Link High Voltage Gas-Insulated Switchgear (HV GIS) to Indonesia’s seismic networks, enabling preemptive circuit disconnection.
o Embed sensors in HV GIS for remote fault detection.
Adaptive Deployment Strategies
o Customize High Voltage Gas-Insulated Switchgear (HV GIS) configurations:
High-risk zones (Sumatra, Java): Deploy 252kV HV GIS with seismic isolation bases.
Coastal areas: Use corrosion-resistant HV GIS enclosures.
o Align HV GIS deployment with Indonesia’s renewable energy grid hubs.
Local Collaboration and Maintenance Training
o Partner with PLN to train engineers in High Voltage Gas-Insulated Switchgear (HV GIS) maintenance.
o Develop emergency protocols integrating HV GIS resilience with ICL early warning systems.
Achievements
Enhanced Grid Reliability
o High Voltage Gas-Insulated Switchgear (HV GIS) maintained zero failures during magnitude 7+ earthquakes, reducing outages by 80%.
o HV GIS early warning systems disconnected lines 30 seconds before the 2024 Papua M7.1 quake, preventing fires.
Reduced Lifecycle Costs
o High Voltage Gas-Insulated Switchgear (HV GIS) compactness cut substation land use by 50% in Jakarta/Surabaya.
o Smart monitoring lowered HV GIS maintenance costs by 30% versus AIS.
Regional Cooperation and Technology Export
o Indonesia’s HV GIS project is a Belt and Road model for the Philippines/Vietnam.
o Local production of High Voltage Gas-Insulated Switchgear (HV GIS) components boosted industrial growth.
