Líquidos e Gás Bomba / Pipeline Aplicações (American Superconductor)

Origin : American Superconductor

Pipelines invest to boost existing capacity and to provide new lines where additional transport is required. Construction and operation economics are driving pipelines towards larger motors in fewer stations. 4160V motors in the 2,000-4,000 HP range are common and large stations are increasingly using 15kV-class motors in the 8,000-15,000 HP range.

Availability of electric power is a major factor in station location and design. American Superconductor’s (AMSC) Power Quality Static Var Compensator (PQ-SVC™) system can
increase usable motor size along with increasing siting opportunities. The highly reliable and cost-effective PQ-SVC system can:

  • Allow increased flexibility in locating stations
  • Reduce utility connection charges and construction lead time
  • Protect operating motors against load sags of up to ~25%
  • Provide increased motor torque under loaded operating conditions
  • Eliminate multiple “point” solutions: motor starters, drivers, etc.




The AMSC PQ-SVC system provides cycle-by-cycle VAR support. With fully automatic controls and passive cooling technology, the system contains no moving parts and requires no regular maintenance. It can run completely stand-alone, or can be easily integrated with existing local and remote control and monitoring systems. Highly compact, a PQ-SVC system can be installed within a limited footprint, in a substation, enclosed or can be placed on a platform between poles. Installation and commissioning is quick and can be complete in a matter of a couple of days.
Companies can realize the benefits of installing a PQ-SVC system when:

  • Using 5 – 15 kV motors that total over 1,000HP
  • Locating multiple pumps or compressors in one location
  • Large substation transformers are required
  • New or upgraded power line is required to operate at the site
  • Operations result in sag and flicker complaints
  • Considering using one or more reduced voltage soft-starter
