Next Generation Variable Speed Drive Boosts Production GCS Electrospeed II lowers power costs for Latin American operator.

Description

The GCS Electrospeed^® 3 is available in two standard enclosures: general purpose NEMA 1 and weatherproof NEMA 4. Each of these enclosures is offered in three frame sizes: 2000, 4000 and 8000. The GCS Electrospeed 3 features all stainless steel fittings to ensure maximum durability, even in harsh environments.

The Centrilift GCS ElectroSpeed 3 variable speed drive is TUV certified to UL specifications in both the United States and Canada. These drives can also bear the CE mark for European Union approval.

The GCS Electrospeed 3 offers as standard a choice of 6-pulse or 12-pulse converter options. Drives with higher pulse count converters can be ordered to achieve IEEE 519-1992 recommended practice for increased harmonic reduction.

The GCS Electrospeed 3 is the only VSD that offers a choice of output waveforms. The GCS Electrospeed 3 with FPWM™ provides state-of-the-art down-hole equipment protection suitable for all applications. The GCS Electrospeed 3 continually monitors the PWM output filter. In the event of a filter failure, the filter is automatically disconnected from the drive output and switched from PWM output mode to 6-step output mode without shutting down the ESP. The GCS Electrospeed 3 allows continued ESP operation without exposing down-hole equipment to damaging unfiltered PWM output spikes.

The GCS Electrospeed 3 is designed to seamlessly interface with down-hole monitors and data communications systems. The GCS interface is engineered to gather and log data from both drive performance and down-hole ESP monitors. Information can then be observed, downloaded to a computer or communicated for remote monitoring and control. Operational parameters can then be analyzed or compared to the simulator in AutographPC^®. When parameters move outside maximum efficiency envelopes, equipment performance can be adjusted through the GCS Electrospeed 3 VSD to optimize well and field performance.

Features and Benefits

• Speed can be increased to counteract ESP wear and maintain maximum production for a longer system life
• Increases power quality by isolating down-hole equipment from damaging power fluctuations
• Reduces starting stress by controlling current levels during start-up, which reduces starting torque, lowers residual heat and extends motor life
• Improves system efficiency by optimizing flow relative to the well productivity index
• Allows motor speed adjustments to match fluctuating well conditions for maximum production
• Increases remote operation capabilities by interfacing with down-hole sensors and communications
• Reduces well lifting costs by reducing generator size, power consumption and down-hole equipment requirements
• Decreases stress on ESP system components by operating at peak efficiency
• Controls motor speed to maintain critical operating levels in the presence of high GOR, high viscosity or sand
