Supervisory control and data acquisition

Energy Analytics and SCADA

Energy analytics and SCADA work together to extend data and expand information visibility, providing a powerful addition to the overall control system. SCADA or Supervisory Control And Data Acquisition is a control system of software and hardware elements that allows manufacturing and process facilities like water treatment plants to:

  • Monitor, gather, and process real-time data
  • Directly control devices such as valves, pumps, motors, and more through human-machine interface (HMI) software.
  • Record events to a log file
  • Notify operators when programmed parameters or trends are out of limits

SCADA can also provide reporting through enhanced visualization to give operators “big picture” views of overall system operation.

Energy Analytics and SCADA integrates well together.

Energy Analytics software systems provide advanced analysis of SCADA parameters and other data sources to enable intelligent decision making input to operators and others.  This can include accessing other computer systems and programs thru an application programming interface or directly from a data base (historian).  Energy analytics combines the information from these data sources using unique algorithms.  An example might be the calculation of true energy cost based on the energy and demand used at a load center in the context of actual utility tariff information.

Who uses SCADA?

In this diagram the Meter is addressing energy analytics and the SCADA system.

Typically, SCADA systems are used to automate complex processes where human control is impractical. Systems where there are more control factors or remote devices need SCADA.  Faster-than-human control factors can also benefit from well-designed SCADA systems. Careful construction of rule-sets can assist system operators with routine management functions.

SCADA systems control:

  • Electric power generation, transmission and distribution
  • Water and sewage
  • Buildings, facilities and environments
  • Manufacturing
  • Mass transit
  • Traffic signals

How is SCADA Integrated with Energy Analytics?

Communications Schema for Energy Analytics and SCADA requests

In energy management, electricity generation and transmission/distribution, SCADA systems will become increasingly more important, as they allow utilities to manage potential negative impacts of DER installations, as well as leverage opportunities to improve reliability. But, to take full advantage of SCADA systems, the data must be available.

Accurate, available and consistent data is essential to any data-driven system. Without data standards and data accuracy checks, utilities cannot trust that their data is organized and presented accurately. But even with high-integrity data, visualization is critical to effective decision making.

PredictEnergy® is integrated with the SCADA system to extend data and expand information visualization and visibility. Both systems function by acquiring and managing data, but, the information is typically in separate data stores. PredictEnergy® integrates with SCADA and works off the same data, but does not access any of the control systems. The visualization and analytics provide powerful decision analysis not normally associated with a SCADA system. The interface requires a understanding of the client’s configuration and integration requirements, but is not overly complex.
