Re-Energizing Pipeline Pump Stations After Hurricane Katrina without Utility Power

This paper discusses some of the issues associated with operating a large products pipeline system, which is typically fed from multiple, very reliable, utility owned electric systems, temporarily on distributed generation. As a result of hurricane Katrina, the heart of the pipeline system was disabled by the loss of 13 pump stations over a contiguous 200-mile stretch. This paper describes the paths taken to re-energize the pump stations using multiple 2000 kW diesel generators connected in parallel to allow a combination of 9000 horsepower to be operated. An introduction to generator "droop circuits" as it pertains to the control of the multiple generators is discussed. The logistical problems that must be overcome when as large an area was affected by a long duration power outage are discussed as well as lessons learned from the experience and recommendations for future preparedness
