From Initial Planningto Integrated Solutions
Power System Planning The first steptowards economical
solutions
The first step towards a new, extended ormodified network always
is a reliable initialplanning. No matter if this step
involvesnetwork analysis, equipment, plant or sys-tem design, or
the integration of variousnetwork components we have the
rightknow-how to perform any of these tasks.Our services include
counselling, powersystem calculation, planning and design aswell as
the analysis of networks of all volt-age levels.Our innovative
approach and experienceof many years allow us to meet all the
de-mands of our customers. To assist us inthis task, we developed
several high-levelsimulation programs such as NETOMAC,the worlds
most powerful tool for calcu-lating electromagnetic and
electromechani-cal transient response, and SINCAL forthe study of
interconnected networks. Wealso perform on-site measurements
andadvise our customers about viable optionsto improve and optimize
their power sys-tem. With our AC/DC real-time simulatorwe determine
control and protection set-tings for HVDC systems, FACTS and pow-er
quality equipment. A team of experts willalways assist you with the
installation andcommissioning of these devices on site.
Decentralized supplies can beplanned-in too
There is no doubt that in the future someexisting large
concentrations of generatingcapacity will be replaced by a larger
num-ber of smaller decentralized units. Suchunits can be powered by
wind, biomass orsolar light and will soon be generating be-tween 10
and 15% of all the electricity thatis needed. Intelligent systems
will providethe control and ensure an optimum energymix.This will
make great demands on the plan-ning and implementation of
integrated en-ergy management systems that cover thewhole
distributed network right up to finalconsumption.Our partnership
with you also means pro-viding generation management, load
man-agement, delivery management and com-munications, with
consumers too, integrat-ed into the network itself. For this
purposewe employ intelligent supply systems, in-cluding subsystems
such as the NEXUS
meter management system, the DEMS de-centralized energy
management system, theSINAUT Spectrum open network controlsystem
and the SICAM system for substa-tion automation.
Project development andconstruction of large-scale systems
Infrastructural and industrial projects call fora broad range of
products and services. Thedemands frequently go beyond the scopeof
just power transmission and distribution.In such cases, your
competent Siemenscontact can open up the door to everythingwe have
to offer in terms of power engi-neering.In international project
business, there isnowadays an increasing trend towards in-volving
consulting engineers, general con-tractors and project
developers.Because of the global interconnection ofthis business it
is essential to have an ef-fective communication in place. With
ourexperience over decades we contribute toan efficient project
execution of such inter-national projects including external and
in-ternal Siemens partners.
Fit for the energy market with integrated IT solutions
With the ongoing development in informa-tion technology IT over
the last decade, it ispossible to build up integrated IT
solutions,designed to solve your problems and helpyou to optimize
your business processes.However, the world of IT is still
character-ized by so-called island solutions, whichshould be
integrated into an overall system.Our IT solutions cover all your
tasks: NetworkManagement, Energy Trading, CustomerManagement and
Business Operations.One good example of our integrated solu-tions
is meter management, where the busi-ness process flow from meter
reading toconsumption billing is efficiently supported.
A partner in system administration
Whether it be extending a system or simplylooking after it
properly, as your partner wecan also undertake all your system and
datamanagement. That could be of great inter-est for large-scale
system administration inconnection with power system management,for
example. Typical tasks of this kind arethe editing of system
parameters, regularchecking of system security and the addi-tion
and editing of mimic diagrams, listingsand records. In this area we
can providebackup either through on-site service or bymeans of
teleservice.

can advise you onhow to finance them in the most suitableway for
you.
