SIPROTEC 5: Multifunctional protection relays

SIPROTEC 5 Device Series, Protection, Control, Automation, Monitoring, and Power Quality

Editorial

SIPROTEC has been a recognized brand leader in digital protec-tion and bay units on the energy market for decades. The Siemens high-performance SIPROTEC devices cover the entire power spectrum and can be implemented in a wide range of fields – from power generation to transmission of very high voltages, distribution network, and industrial applications.

SIPROTEC 5 is an active component of the secure smart power system, and an important building block in the complexity of distributed energy-supply systems and networks solutions.

The SIPROTEC 5 generation of devices provides you with a modern platform of both hardware and software. This platform offers an excellent solution to the challenges associated with evolving grid structures and workflows. The quality, reliability, and proven functions of the SIPROTEC 4 device range have been preserved. Innovative approaches including holistic workflow, safety and security, and network-stability monitoring (PMU func-tionality) have been added.

Integrated and upgradeable functionalities for your efficient network operation:

• Various sensitive ground fault and ground-fault location methods for fast fault location

• Voltage control for transformers for cost optimization – also for parallel transformers

• PMU function for network-stability monitoring

• Adaptive adaptation of the protection parameters via

IEC 61850 to increase the network load

• Protection of complex network structures, such as capacitance banks or multi-end topologies

• Process-bus applications according to IEC 61850-9-2 digitize the measured data directly at the measuring point

• IoT interface to cloud applications such as MindSphere with the standard protocol OPC UA PubSub for easy use of data from the bay, for example SIPROTEC Dashboard

• Extensive cybersecurity functionality, such as role-based access control (RBAC), logging of security-related events, signed firmware, or authenticated IEEE 802.1x network access.

The Benchmark for Protection, Automation, and Monitoring

The SIPROTEC 5 series is based on the long-term field experience of the SIPROTEC device series and has specifically been designed for the new requirements of modern power systems. For this purpose, SIPROTEC 5 is equipped with extensive functionalities and device types. With the integrated and consistent DIGSI 5 engineering tool, a solution has also been provided for increas-ingly complex processes, from design through to the engi-neering phase, up to testing and operation.

Thanks to the high degree of hardware and software modu-larity, the functionality of the device types can be tailored to the requested application and adjusted to the ever-changing requirements throughout the entire lifecycle.

In addition to the reliable and selective protection and the complete automation function, SIPROTEC 5 offers an extensive database for operating and monitoring modern power systems. Synchrophasors (PMU), power-quality data, and extensive equipment data are included in the functionality.

• Powerful protection functions ensure the safety of equipment and staff

• Individually configurable devices save money on the initial investment and on spare-parts storage, maintenance, exten-sion, and adaptation of your plant

• Arc protection, transient ground-fault detection, transformer control, and process bus can easily be integrated and retro-fitted

• Purposeful and easy handling of devices and software thanks to a user-friendly design

• Increased reliability and quality of the engineering process

• High operational safety due to the consistent safety imple-mentations

• Highest availability even under extreme environmental condi-tions due to the coating on the electronic modules

• Integrated switch for low-cost and redundant optical and elec-trical Ethernet rings

• Redundancy protocols RSTP, PRP, and HSR for maximum avail-ability

• Efficient operating concepts due to flexible engineering of IEC 61850 Edition 2

• Comprehensive database for monitoring modern power systems, also with IoT cloud connection

• Optimal smart automation platform for your power systems based on integrated Phasor Measurement Unit (PMU) and Power Quality functions.
