Hybrid System Supervisory Controller

The Sustainable Power System Supervisory Controlleris a control panel typically located in the plant control room that serves as the top-level controller and the primary operator interface for the entire system. For example, a wind-diesel hybrid power system supervisory controller performs the following tasks:

• Diesel dispatch
• Starting and Stopping the diesel generator(s) according to the diesel capacity required.
• Diesel status monitoring.
• Wind turbine dispatch
• Allow/inhibit wind turbine operation as necessary.
• Secondary load dispatch
• Determining the required amount of power sent to the secondary load at any given instant.
• GFI dispatch
• Utilizing the inverter and battery bank to run in true diesel-off mode, or supplementing real/reactive power for balance of the plant.
• Performance data logging
• kWh and run-time totals, alarms, etc.
• Fault detection and annunciation
• Provide for remote access via internet connection.

The heart of the supervisory controller is an industrial-type panel mount PC computer with color touch screen monitor. Sustainable Automation prefers this platform for top level supervisory control, because it offers ease of implementing complex dispatch algorithms, creating powerful operator interfaces, and offering a variety of options for remote connectivity. The operator interface provides great flexibility to change the operating strategy through a variety of user-settable parameters.
