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

Konteksto ng Proyekto: Suporta sa 900MW na integrated solar PV + energy storage project sa loob ng MBR Solar Park ng Dubai, na nag-ooperate sa isang mahigpit na coastal desert environment na may ekstremong temperatura (hanggang 55°C) at corrosive sand/salt conditions.

Hamon: Pag-deliver ng reliable, high-efficiency power transformation para sa parehong PV array at co-located Battery Energy Storage System (BESS) sa ilalim ng mahihirap na kondisyon ng desierto habang pinapahintulot ang seamless grid integration at minimization ng installation time.

Solusyon sa Transformer:

Step-Up Transformation ng PV Array:

Paggamit: Paggawa ng voltage mula sa PV arrays hanggang 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).
Pangunahing Benepisyo: Ang prefabrication ay significantly reduces on-site installation time and complexity, crucial para sa large-scale desert deployment.

Interface Transformation ng BESS:

Paggamit: 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).
Kritikal na Katangian: Ang OLTC ay sigurado ang stable grid voltage levels sa pamamagitan ng dynamic adjustment ng transformer ratio under varying load conditions (charging/discharging), maximizing grid stability and BESS performance.

Mga Teknikal na Highlight na Tumutugon sa Kondisyon ng Desierto:

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: Ang mga transformer enclosures ay may durable Aluminium-Magnesium (Al-Mg) Alloy coating. This specialized finish provides superior resistance against:

Abrasive Sand Erosion: Proteksyon ng mga sensitive components mula sa pervasive desert sand.
Coastal Salt Mist Corrosion: Essential given the project's proximity to the coast, preventing accelerated degradation.

Optimized Logistics & Installation: Pre-assembly ng 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.
