Principle of AzElConLU

Explanation AzElConLU

• Functions according to process flow chart
• Software monitoring of motors
• ….
• Current protection control of booth motors
• Radio Frequency transmitter & receiver to build a self learning network
• Collect weather data to transmit to AzElConCU (no wires to central unit!)
• External connection only for current supply  minimal cabling costs
• Simple assemble & maintenance: only one electronic box
• Operation also possible stand alone without AzElConCU

Objectives & Benefits

• Low costs
• Cabling on a very small scale
• RF Communication (no wires, no cables)
• Hardly any wires to meteorological station
• Flexibility
• Operation with or without central unit AzElConCU
• No limited amount of local units AzElConLU
• Quick assembly – only one component
• Optional possibility to communicate with power inverter
• Smoothing of power usage
• Free scalable shifted switching of each AzElConLU

Principle AzElConCU (central unit)

Explanation the central unit AzElConCU

• Connection
• Data for meteorological station from local units
• Literally unlimited number of AzElConLU accessible (privat network)
• Preface
• Redundant design
• No rotating components
• Industrial housing
• Regulating and control of local units AzElConLU
• Supplies AzElConCU monitoring
• Internetconnection (for mobil phone and landline?)
• User surface in multilangual incl. three-level authority concept
• Windows Embedded System
• Database SQL Server
• Specification control function
• Option: Automatic messaging (SMS, Email,…)

Principle of AzElConCU – Monitor

Explanation AzElConCU – Monitor

• General:
• Redundant control system without rotating pieces,…
• Windows OS
• Accessible via internet
• Database with standardized datamodel
• Standard evaluation (3 kinds)
• User surface
• Three levels for authority concept
• Accessibility for remote control
• Specification for graphical visualisation [based on business studies]
• Additional options (with costs)
• Special customer demands
• Analysis,
• Regulatory reporting,…
• Multidimensional tools for analyzing

AzElConISLAND: Features of power…

• ..generation
• Parallel operation of power generation and handling of consumer

load

• Take over of power is guaranteed, i.e.
• Excess energy will be destroyed
• Unneeded power will be avoided in first place
• ..storing
• Operating of the AzElConPARC must be ensured at any given time
• Storing is adjusted to the intended demand of energy.
• Currently stored energy is known by the system.
• ..forecast
• Approximation of available energy and - when indicated - a

preventive shutdown of consumer load could be implemented as an option.
