1500V 450kW String Inverter for Large-Scale Renewable Energy Power Plants
TBEA introduces its latest innovation for large-scale renewable energy power plants—the 1,500V 450kW string inverter. Boasting exceptional environmental adaptability, it operates efficiently in temperatures ranging from -40°C to 70°C and maintains full performance at altitudes up to 5,000m, with a corrosion resistance rating of up to C5-H. Performance enhancements include a 15% increase in power density, a 20% wider MPPT full-load voltage range, and a 1000Vac output that reduces cable costs. These improvements, combined with intelligent O&M features such as integrated IV+CV diagnostic technology and component-level monitoring, result in a 40%+ increase in operational efficiency and a 1%-2% reduction in LCOE.
2000V 450kW String Inverter for Higher Efficiency and Reliability
For applications demanding even greater efficiency and reliability, TBEA unveils the 2,000V 450kW string inverter with a 2,000Vdc/1,140Vac design. This inverter reduces BOS costs, increases conversion efficiency by 0.2%, and offers a 37% improvement in volume power density compared to previous models.
TB-Tracker 1P Smart Tracking PV Mounting System
The upgraded TB-Tracker 1P smart tracking PV mounting system leverages high-precision intelligent tracking algorithms to dynamically optimize component tilt angles in real-time, responding to changes in sunlight. Certified by the EU CE and UL, the system demonstrates a 10%-20% increase in power generation over traditional fixed mounts across diverse scenarios, including deserts, hilly terrains, and agri-PV applications. Its intelligent O&M capabilities, based on TBEA’s mature PV power plant management system, utilize astronomical algorithms and inverse tracking technology to maintain optimal generation angles, further increasing power output by 5%. In extreme weather conditions, the system automatically activates smart risk-avoidance modes.
Energy Storage AC/DC Integrated System Solution
Addressing the need for robust, stable, safe, and cost-effective grid-forming string energy storage systems, TBEA introduces its energy storage AC/DC integrated system solution. Featuring a modular pre-installed design, it reduces commissioning time by 50% and installation time by 80%, while saving over 21% in footprint with its “side-by-side, back-to-back” field layout. The system incorporates fully internalized DC cables and an all-liquid cooling temperature control system, along with a three-layer protection design, enhancing overall safety. Multi-level cluster control technology improves system conversion efficiency by 2.2%, increases annual discharge capacity by over 8%, and reduces LCOS by 6.5%.
String Energy Storage Converter (TE430K-HV-BL)
The TE430K-HV-BL string energy storage converter features an all-intelligent liquid-cooled, high-density, compact design, offering a 35% increase in volume power density and a 43% increase in weight power density compared to previous models, saving 10% in footprint. It is compatible with 600Ah+ and 314Ah battery cells in clusters. The TE-PowerHUB platform enables millisecond-level grid-following/forming switching, with IP66+C5 protection for high and low temperatures and salt spray environments.
Clean Air Insulated Vacuum Breaking Eco-Friendly GIS for Renewable Energy Distribution
In the realm of renewable energy distribution, TBEA’s 126kV vacuum breaking eco-friendly GIS stands out for its environmental friendliness, safety, and cost-effectiveness. Unlike traditional high-voltage switchgear relying on SF6 for insulation and arc quenching—a gas with a greenhouse effect 24,800 times that of CO₂—TBEA’s GIS uses clean air instead, leveraging “vacuum arc quenching + clean air insulation” to achieve equivalent or better arc quenching capabilities and operational reliability without greenhouse gas emissions. It is estimated that a single 126kV vacuum breaking eco-friendly GIS device can reduce CO₂ emissions by approximately 4,000 tons over its lifecycle, equivalent to the annual emissions of 600 households.
Flexible HVDC Transmission: Revolutionizing Power Transmission
Flexible HVDC transmission is a revolutionary technology in power transmission, enabling long-distance, large-capacity transmission and efficient integration and consumption of large-scale renewable energy. Its rapid power regulation, strong reactive power, and voltage support capabilities enhance grid flexibility and stability. TBEA showcases four core products for flexible HVDC transmission solutions:
±800kV/5000MW Flexible HVDC Converter Valve: The world’s first ±800kV/5000MW flexible HVDC transmission system converter valve, featuring unblocked overhead flexible HVDC transmission technology, elevates the voltage level from ±500kV to ±800kV and increases transmission capacity from 1 million kW to 5 million kW, achieving industry-leading performance indicators.
DC Link Capacitor for Flexible HVDC Converter Valves: The “DKMJ2.8-7500” DC link capacitor, independently developed by TBEA and passing national technical appraisal in November 2024, reaches industry-leading performance levels, reducing supply chain risks and becoming a core product for deep-sea offshore wind farm integration and novel power system construction.
Bridge arm reactors serve as the critical “link” for power transmission between converter valves and AC systems in ±800kV Ultra-High Voltage Direct Current (UHVDC) transmission projects. As a core component in these projects, they ensure the efficient and stable transfer of DC electrical energy between the converter valves and the AC grid. This pivotal equipment not only transmits substantial amounts of power but also, leveraging its unique electrical properties, enables precise regulation of the transmitted power. The bridge arm reactors developed by TBEA have been applied in the Wudongde Hydropower Station, significantly enhancing transmission efficiency and reducing energy losses, thereby setting a new milestone in the advancement of UHVDC transmission technology.
In UHV transmission systems, dry-type air-core smoothing reactors effectively suppress harmonic currents within the DC system, improving power quality and reducing losses across the power grid. Additionally, they act as current limiters during system faults, preventing excessive currents that could damage equipment. By providing a robust “safeguard” for UHV transmission, these reactors ensure the reliability and safety of power delivery.
