High-speed electric drives for gas pumping stations

High-speed electric drives based on the electric motors with permanent magnets are designed for use in electrically driven gas pumping units at gas pumping (gas-compressor) stations.

An electric drive consists of an AC electric motor with permanent magnets and a frequency converter with a control system.

Electric drive provides:

  • Start-up and acceleration of the pump to a specified speed and the pump shutdown from the specified speed
  • Keeping of the necessary technological parameter (speed, pressure, flow, etc.) according to the specified program
  • The electric drive parameters and operating modes monitoring
  • The protection mode of operation and the electric drive abnormal parameters monitoring in case of failure and (or) emergency

Electric drive main technical characteristics:

  • Nominal power: up to 8 MW
  • Rotation speed: 8000 rpm
  • Range of the speed control: 50-105%.

Motors are explosion-proof with "p"- type explosion protection (filling or purging of the motor case with excessive pressure).

Frequency converters are designed for normal conditions and can be made in modules for outside location.

Operational advantages:

  • Substantial energy savings (up to 30%) due to the flexible speed control and high efficiency
  • Start-up mode can be made without a disturbances in the power net
  • Operating costs reduction due to absence of the mechanical shocks at start mode and exclusion of the units that require a special service (gear unit)
  • Improved reliability and reduced service time of the equipment
  • Improved reliability and reduced equipment downtime
  • Improved mass-dimensional figures (1.5-2.0 times)
  • High mass-dimensional parameters
