Some Statements on “Smart Grids”
We need
more
information
We need to adapt our grid
to get all opportunities in
place born by new
technologies.
More flexibility to be
able to follow new
regulations.
More reliability
to secure power
supply by
differnet sources.
The complexity of
the already complex
electrical system will
increase.

The Siemens Smart Grid Vision
is driven by the requirements of our customers
Flexibility: fulfilling customers’ needs whilst responding to the changes and
challenges ahead
Accessibility: granting connection access to all network users, particularly for
renewable power sources and high efficiency local generation with zero or low
carbon emissions;
Reliability: assuring and improving security and quality of supply, consistent
with the demands of the digital age with resilience to hazards and
uncertainties;
Profibility: providing best value through innovation, efficient energy
management and ‘level playing field’ competition and regulation.
The Siemens approach is to focus on each customers needs to evolve
(migration) its grid to smart grid

Condition monitoring for controlled overload of
bottlenecks and reliability centered asset managem.
Definition
Condition Monitoring is any kind of system or service giving
an information on the ageing or health condition of a primary
device in operation, derived from special sensor and/or from
data typically available.
