VARIABLE SPEED DRIVES
Variable speed drives (VSDs) are used to control electrical submersible pumping (ESP) systems and surface pumps. They enable adjustments to be made to production parameters and ESP output when downhole conditions change. Increasing and decreasing motor speed can be used to optimize pump performance, speed or slow production, and avoid gas locking and system cycling. VSDs protect pumps and motors by reducing electrical stress on startup and by adjusting to dynamic conditions as they change. The ability to vary the drive speed reduces the need to replace components, cuts downtime, and lowers costs while improving system runlife.
BENEFITS
Reduce voltage stress to extend runlife of the motor, cable, and electrical components
Reduce cycling and sudden impacts to the system to protect pump components
Increase or decrease RPMs to enhance production and avoid locking or cycling
applications
- ESPs driven by permanent magnet motors and asynchronous induction motors
- Surface pumping systems
- Water injection systems
capabilities
- Variable speed ESP control
- Self-diagnostics
- Onsite and remote control
features
- Programmable controller enables scheduled, manual and automated startup
- The sine filter reduces voltage stress on the motor and cable
- An uninterruptible power supply keeps the system running through power fluctuations
- Optional skid mounting protects the system and makes moving easy
