Universal Microgrid ControllerTM(Hybrid System Supervisory Controller)
• Monitors and coordinates the operation of all system components
• Touchscreen local operator interface
• On-board datalogging• Internet ready • Modular software –
modules pre-coded to enable use with all major models of wind turbine and diesel generator controllers.
Secondary Load Controller
• Diverts excess wind power to an electric boiler in the diesel plant heat recovery loop.
• Zero-crossing solid state switching → no harmonics
• Power control or frequency control
• Fast response – (3 msec)• Easily scalable
Synchronous Condenser
• Standalone or diesel-parallel operation
• Assists diesels (or inverter) in meeting reactive power demand
• Regulates voltage in standalone mode
• Magnetic “mass” provides additional voltage stiffness
• Rotating mass provides additional frequency stiffness
• Provides fault clearing current
