High focus on safety

For personnel

For laboratory and test components

Easy adaptability of control and safety functions

Test and safety procedures can change over the time

Visualisation and HMI

SCADA, visualization and reporting

The main interface for the test engineer

How to handle and display large amount of information



All research concepts must NOT influence any test procedures

Integration of new automation and control concepts for Smart Grids

Needs a flexible solution

Must be executable parallel to the test automation

Communication concepts for Smart Grids

Possibility to easily exchange communication protocols

Support for different mediums

Design and validation

Support for design and validation of new methods and concepts

Summary and Conclusions

Development of a Smart Grid lab automation using mainly open source tools

4DIAC, ScadaBR, openPOWERLINK and libmodbus

Time consuming integration but very flexible and highly configurable

4DIAC as integrating middleware

Through portability available for multiple platforms, currently used on

• Notebooks and standard PCs (Windows and Linux)

• Industrial PC (Windows Embedded and Linux)

• Embedded Controllers (Embedded Linux)

As common interface between SmartEST and other automation projects

• Portability and exchangeability of control applications

• Configurable communication gateway to Smart Grid components

(e.g., intelligent inverter systems)
