Siemens Power Transmission and Distribution (PTD) is
to supply state-of-the-art power system control to equip Russia’s
extra-high voltage power system. In this way the System Operator-Central
Dispatching Office for Unified Energy System of Russia (SO-CDU UES) is
responding to the requirements of the deregulated Russian energy market. The
new Siemens system will replace the existing systems and will add new
functions. The use of the new system guarantees higher operating reliability of
all equipment, a reduction of overall network losses and improved utilization
of power plant capacity. The order has a value of about 80 million euros;
commissioning is planned for the middle to end of 2008.
Russia is not only the world’s
largest country in terms of surface area. It also has one of the largest and
most complex power networks in the world with correspondingly high requirements
as regards data volume and the efficiency of the power system control. The
complete system for the Russian 220-kV and 500-kV extra-high voltage system to
be delivered by Siemens consists of the central power system control center in Moscow and seven supraregional
control centers distributed across the whole of Russia. Two of these supraregional
control centers are configured as backup control centers for the central power
system control center.
The
power system control which is based on the latest Advanced-PowerCC architecture
provides the necessary SCADA/EMS/EMM functions for real-time monitoring of the entire extra-high voltage network.
Furthermore, the system provides all interfaces and programs for data exchange
with the operator of the power trading system and all other market players such
as distribution companies, producers and qualified users.
The system
operates with open standards such as the IEC 61970 standard for the CIM data
model and the relevant program interfaces and with IEC 60870-5 and IEC 60870-6
for communication and data exchange with other systems. In this new project for
Russia all data relating to the extra-high
voltage network will also be gathered centrally in the internationally
standardized CIM format for the first time. These standards create the basis
for expansions such as are to be expected in an increasingly deregulated energy
market. Siemens is making allowance for the specific requirements of the
Russian market model for the deregulated energy market with energy management
functions (EMS) and energy market management functions
(EMM) matched specifically to the stipulations of the Russian market
regulations.
