VSD – Flexible Adjustment and Precise Control

A proprietary development, timely monitoring, versatility in application and use – all of this refers to the Variable speed drives with frequency regulation produced by Novomet, designed for managing ESP installations and systems for liquid transfer.

Variable speed drives effectively handles the task of regulating the motor speed, adjusting extraction parameters and installation performance according to changes in well conditions. By increasing or decreasing the pump motor's RPM, the control stations optimize the extraction process, prevent gas lock formation, reduce starting voltage, enhance starting torque during challenging starts, and protect against turbine rotation, overheating, overloads, and other emergency situations. This ultimately extends the lifespan of the motor, cable, and electrical components, thereby eliminating downtime and operational costs.

“Variable speed drives were the first in our company’s import substitution program,” says Denis Naumov, Deputy Head of the Control Stations Bureau at Novomet. “Our specialists have developed a completely independent product that does not rely on sanctioned components. This has made Novomet's variable speed drives more maintainable and versatile. Previously, in case of breakdowns, it was necessary to call specialists and send equipment back to the supplier; now maintenance can be performed directly at the field site or at the customer’s base. The convenient design allows one person to replace any element in the control station within 30 minutes.”

Variable speed drives can connect to any installations and manage asynchronous and valve motors. Their uniqueness lies in their ability (and only theirs) to work with high-speed ColibriESP installations. The resonance suppression function allows for adaptation to any valve electric motors. Multiple climatic versions enable the supply of stations worldwide.

Novomet’s variable speed drives have proprietary software. The programmable controller provides scheduled startup, manual and automatic operation, features an informative color display, and includes a Wi-Fi module. Software updates can occur without stopping the station via a USB port. Archives can also be downloaded through the USB port onto a standard flash drive. The advantage of Variable speed drives lies in its self-diagnosis and hint system. The causes of malfunctions can be easily checked remotely without opening the station or involving additional specialists, as errors are deciphered and understandable to operating personnel. Current software can be found on Novomet’s official website. The built-in router option allows remote monitoring of installation parameters and archiving through Novomet Track's remote monitoring system.

The built-in output sine filter reduces the load on the submersible motor and cable line. The built-in uninterruptible power supply ensures controller operation during input voltage drops for up to 3 minutes.

In summary, this is a unique import-substituting product developed by Novomet specialists that meets all necessary characteristics for uninterrupted and optimal operation of ESPs.
