PdM for Power Generation

Serving the needs of the electric power generating industry in all sectors of power generation including wind, hydro, fossil fuels, nuclear, co-generation, geothermal, solar and biomass.

Critical assets to monitor

In a complex operation like power generation nearly all components are critical, as the loss of one unit can affect many other units down the line, effectively taking a plant offline, or severely limiting the output. The most critical assets that should be closely monitored are turbines, generators, boiler feed-water pumps and ID/FD Fans. These most critical assets have no backup units associated, and machine failure would severely de-rate the plant output, or take it offline completely. If this occurred the asset replacement cost is extremely high, and time consuming to get back online. Generally, a majority of other units can be offline for extended periods of time with reduced impact to production.

Best PdM technologies to apply

  • Vibration Analysis covers the widest spectrum of measurable faults in any rotating asset regardless of its driver (steam, electric, internal combustion). Vibration is the most cost-effective method of providing a total overview of a facility’s health.
  • Oil Testing benefits include the ability to detect wear particles from early bearing / gear wear far in advance of vibration detecting degradation. Oil analysis only provides information of wear particle detection, and cannot provide information the wide array of mechanical fault detections that can be learned with regularly scheduled vibration collections.
  • Motor Testing much like oil analysis is pinpoint-specific to its role, however, motor testing done at periodic intervals can detect issues that no other PdM technology can. Motor testing can determine particular electrical faults early on that can be dealt with at relatively low-cost and with minimal downtime versus a core loss instance on a motor, costing hundreds of thousands of dollars in repair costs not to mention the losses attributable to downtime. Infrared can detect loose wiring connections, connector integrity trouble, and excessive current or heat dissipation due to overloading. Infrared is extremely beneficial in shooting yards, MCC buckets and connection heads on motors.
