The Smart Grid
is no revolution
but rather an
evolution

or a process

In
addition to “Smart Devices (IEDs)” there will be “Smart Substations”, “Smart
Primary Equipment
”, “
Smart Appliances

ABB
has been providing components, subsystems and complete Smart Grid
solution backbones for 25 years, thus we are well prepared for the further
evolution of
the Smart Grid.

Case

The
results

and the
conclusion


Improved network reliability and enhanced power quality


The data quality is improved and quantity decreased, which is transfered to the control centre


Advanced station level reporting reduces the amount of non
-
processed data sent to operators


control
center can focus on overall coordination tasks.


By adding information from all system levels of the distribution network the accuracy of the fault
location was enhanced.
