Abstract
Embodiments of the invention provide a condition-based maintenance tool that may be used to monitor, configure, and in some cases correct, problems experienced by a compressor in a pipeline system. The condition-based maintenance tool may evaluate data retrieved from a compressor status database to identify overconsumption events. In response, the maintenance tool may generate maintenance alarms, initiate work orders, and/or provide recommendations for action to an operator.
Claims23
A computer-implemented method of performing condition-based predictive compressor maintenance, comprising:
- determining an estimated power consumption level of a compressor for a given time period;
- monitoring one or more operational parameters of the compressor during the time period and an actual power consumption level of the compressor during the time period;
- determining whether a power over consumption event has occurred, based on the estimated power consumption level and the actual consumption level;
- upon determining a power over consumption event has occurred, evaluating the monitored operational parameters to determine an appropriate corrective action;
- and
- performing the corrective action for the overconsuming compressor.
A computer-readable storage medium containing a program configured to perform condition-based predictive compressor maintenance, the program including instructions for performing an operation, comprising:
- determining an estimated power consumption level of a compressor for a given time period;
- monitoring one or more operational parameters of the compressor during the time period and an actual power consumption level of the compressor during the time period;
- determining whether a power over consumption event has occurred, based on the estimated power consumption level and the actual consumption level;
- upon determining a power over consumption event has occurred, evaluating the monitored operational parameters to determine an appropriate corrective action;
- and
- performing the corrective action for the overconsuming compressor.
A system for performing condition-based predictive compressor maintenance, comprising:
- a supervisory control and data acquisition system used to monitor a set of operational parameters one or more compressors in a pipeline and an actual power consumption level of the compressor during a time period;
- a compressor status database configured to record values for the operational parameters and the actual power consumption level during occurring the time period;
- and
- a diagnostic and maintenance tool configured to:
- determine an estimated power consumption level of a compressor for the time period,
- determine whether a power overconsumption event has occurred, based on the estimated power consumption level and the actual consumption level,
- upon determining a power overconsumption event has occurred, evaluate the monitored operational parameters to determine an appropriate corrective action, and
- perform the corrective action for the overconsuming compressor.
