Pag-optimize sa Power sa Desierto: Mga Solusyon sa Photovoltaic Transformer para sa UAE Solar Revolution

Optimizing Desert Power: Photovoltaic Transformer Solutions for the UAE Solar Revolution

​Konteksto sa Proyekto:​​ Suporta sa 900MW na integrated solar PV + energy storage project sa MBR Solar Park sa Dubai, operasyon sa demanding coastal desert environment nga gipangitaan sa extreme temperatures (hangtod sa 55°C) ug corrosive sand/salt conditions.

​Hamubo:​​ Pag-deliver og reliable, high-efficiency power transformation para sa PV array ug co-located Battery Energy Storage System (BESS) sa harsh desert conditions habang pag-enable sa seamless grid integration ug pag-minimize sa installation time.

​Transformer Solution:​​

1. ​PV Array Step-Up Transformation:​​
• ​Aplikasyon:​​ Boosting voltage gikan sa PV arrays ngadto sa medium-voltage collection grid.
• ​Teknolohiya:​​ Dual-winding liquid-filled transformers.
• ​Kapasidad:​​ 3150kVA.
• ​Voltage Conversion:​​ 1500V DC Input (via inverters) → 33kV AC Output.
• ​Form Factor:​​ Skid-mounted Pad-Mounted Units (integrated into prefabricated electrical houses - e-Houses).
• ​Key Benefit:​​ Prefabrication significantly reduces on-site installation time and complexity, crucial for large-scale desert deployment.
2. ​BESS Interface Transformation:​​
• ​Aplikasyon:​​ Interfacing ang Battery Energy Storage System (BESS) sa 33kV AC grid, enabling bidirectional power flow.
• ​Teknolohiya:​​ Liquid-filled transformers with On-Load Tap Changer (OLTC).
• ​Voltage Conversion:​​ 33kV AC → 400V AC (Supports bi-directional flow for Charge & Discharge modes).
• ​Critical Feature:​​ OLTC ensures stable grid voltage levels by dynamically adjusting the transformer ratio under varying load conditions (charging/discharging), maximizing grid stability and BESS performance.

​Technical Highlights Addressing Desert Conditions:​​

• ​Advanced Thermal Management:​​ Equipped with an ​Intelligent Hybrid Cooling System​ combining ​forced-air​ fans and ​auxiliary liquid cooling loops. This robust system is precisely engineered to ensure optimal operating temperatures and maintain high efficiency even during peak solar irradiance and ambient temperatures exceeding ​55°C.
• ​Enhanced Environmental Protection:​​ Transformer enclosures feature a durable ​Aluminium-Magnesium (Al-Mg) Alloy coating. This specialized finish provides superior resistance against:
• ​Abrasive Sand Erosion:​​ Protecting sensitive components from pervasive desert sand.
• ​Coastal Salt Mist Corrosion:​​ Essential given the project's proximity to the coast, preventing accelerated degradation.
• ​Optimized Logistics & Installation:​​ Pre-assembly of PV transformers within robust e-Houses ensures quality control, minimizes site work, accelerates project timelines, and protects internal components during transport and installation in a challenging environment.
