Invited Session: Energy Recovery

Smart Control Systems: Maximize Plant ROI and Support Preventative Maintenance (0.5 CEU)

Tuesday, September 26, 2017
16:15 – 16:45
Room 320

Moderator: Edward Krisiunas, Owner, WNWN International, Connecticut

A Supervisory Control and Data Acquisition (SCADA) system is much more than a landfill gas power plant control and management tool. It can be specified and designed to serve as an information powerhouse to help owners and operators more effectively operate and maintain their equipment. Performance reports created by a SCADA system not only show power generation production, they also provide the data necessary to schedule maintenance (scheduled and condition based). By monitoring and logging turbine hours, for example, operators can see when generator maintenance should be scheduled based on system specifications and plan accordingly. Most plants have a regular shutdown schedule for maintenance (e.g., once per month), but the data from a SCADA system also allows operators to make the crucial call to shut down plant operations ahead of schedule to avoid poor performance or equipment failure. Collected data helps troubleshoot problems by archiving data from past months or years, and helps owners better report on plant efficiency to utility and state monitoring agencies.

Following the presentation, participants will be able to:

  • Design your plant control system for maximum ROI by using a scalable and comprehensive SCADA system, and specifying the right data points for real-time and historical analysis
  • Prioritize maintenance, optimize operations, and proactively identify potential problems to ultimately exceed expected plant performance
