Medium & High Voltage VFD Solutions for Oil & Gas Industry
Sunsin three-level medium voltage drives feature anti-corrosion and low harmonic performance, ideal for onshore oilfields, offshore platforms and FPSO oil & gas projects.
- Unstable remote oilfield grid:Onshore oilfields suffer severe voltage surge, drop and unbalanced power supply, causing ordinary VFD frequent tripping.
- Offshore salt spray & corrosion:Coastal and platform environments feature high humidity and salt fog, which easily erode open-type drives and accelerate equipment aging.
- Long-term continuous heavy load:Water injection pumps and gas compressors run 24/7, requiring high stability and overload resistance.
- Strict offshore power quality requirements:Platform microgrids are sensitive to harmonics; ordinary two-level inverters interfere with precision instruments and control systems.
- High energy consumption of fixed-speed equipment:Traditional constant-speed pumps and compressors cause massive energy waste during variable production demands.
Core Advantages
Targeted optimized VFD design for petroleum industry
Low Harmonic & Microgrid Compatibility
Adopting three-level NPC topology and optimized SVPWM modulation, the VFD outputs ultra-clean current with extremely low THD. It avoids interference with offshore instruments, automatic control systems and platform power grids, fully meeting petroleum industry power quality standards.
Salt Spray & Corrosion Resistance
Sealed IP54 cabinet and special three-proof coating for internal circuit boards effectively resist salt fog, moisture and corrosive gas. The whole machine adapts to long-term offshore and coastal harsh environment operation.
Strong Weak Grid Adaptability
Built-in grid adaptive algorithm and wide voltage tolerance design. The drive can resist frequent voltage fluctuation in remote oilfields and maintain stable output without overvoltage or undervoltage tripping.
High Energy Saving & Stable Heavy-duty Operation
Realize stepless speed regulation for oilfield pumps and compressors according to actual production demands. 15%-35% comprehensive energy saving rate, supporting 24/7 continuous heavy-load operation without performance attenuation.
Main Application Scenarios
Our drives deliver stepless speed regulation, low harmonic output and anti-corrosion performance, adapting to onshore oilfields, offshore rigs and FPSO vessels for long-term continuous heavy-duty operation.
