Greentech Lead America: Siemens has launched its new protection
device series Siprotec 5 for high voltage power transmission systems.
Siemens claims that these numerical bay units with their
modular-structure hardware and software are developed for protection,
automation, measurement and monitoring in high voltage power
transmission systems.
The Siprotec 5 features end-to-end engineering,
individual configurability and safety mechanisms in all links of the safety
chain. Intelligent automation functions and communication as a central part of
the system architecture are also featured, along with implementation of Edition
2 of the international communication standard IEC 61850 for energy automation.
Intelligent energy automation can stabilize power
transmission systems and at the same time help save on both energy and costs.
“We conceived the devices for the requirements of a
changing energy market. In protection relaying and automation, the challenges
can be met by energy trading and by increasing infeed from renewable and
decentralized energy sources into the high-voltage grids,” said Jan
Mrosik, CEO of the Smart Grid Division of the Siemens Infrastructure &
Cities Sector.
The Siprotec 5 devices cover a range of applications in
high-voltage transmission, such as distance protection, line differential
protection, bay control and breaker management. They form a data basis for
power quality and for monitoring of electrical power supply equipments.
The modular-structure hardware and software enable the
configuration of application-specific devices. To protect the equipment,
Siemens has integrated complex safety mechanisms.
The Digsi 5 tool forming part of the protection device
range allows integrated, uniform system and device engineering, all the way
from the circuit diagram of a substation to device parameter setting and the
graphic linking of primary and secondary equipment. Open interfaces enable
integration into the user’s processes.
The devices can be adapted via plug-in and add-on modules
to the topology of the user’s communication structure. The requirements in
terms of necessary cyber security were incorporated in the system design of
Siprotec 5, in order to take account of the worldwide trend toward IP-based
communication.
Recently, Siemens
announced that Burlington Electric Department (BED), the electric service
provider of the City of Burlington Vt., selected Siemens for the sale and
implementation of the eMeter EnergyIP meter data management (MDM) platform.
