Abstract:

Most compressor station Gas Turbine units have a number of battery powered emergency back up dc motors driving the vent fans, lube pumps etc. which are started in the event of a mains power failure. Currently these motors are started from resistor type starters located within each compressor unit's dc motor control centre.

At a number of compressor stations these resistor starters have overheated causing damage to the control equipment and constituting a fire risk.

It is proposed to replace these with a new dc electronic motor starter. DC electronic motor starters are not available as off the shelf products for a dc battery supply and will therefore require design and development. A prototype will be designed and tested and then a working unit will be installed at Wooler compressor station for a trial followed by the installation of the remaining 2 within the unit.

The objective of the project is to develop a safer and more reliable alternative to the resistance type motor starters currently installed on compressor sites.

A single DC electronic drive was manufactured as a prototype and tested on a load bank. Following successful completion of the test phase three units were manufactured and installed on an operational site. These are now fully installed and operational. The project is now closed
