Hybrid Power System Supervisory Controller
 Sustainable Automation's Wind Turbine Supervisory Control and Data Acquisition System. This unit will monitor and control a small wind farm in the Selawik wind-diesel hybrid power project in arctic Alaska.
The Sustainable Automation Power System Supervisory Controller is 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
• 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
• Diesel status monitoring
• Wind turbine status monitoring
• Performance data logging
- kWh and run-time totals, alarms, etc.
• Fault detection and annunciation
• Provide for remote access via dialup or 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.
