ABB’s protection control and monitoring railway solution
Rapid urbanization and the urgent need to reduce carbon emissions are driving substantial new interest and investment in the transportation sector. The demand for space on the rail tracks is high and on the rise. We need to make better use of existing infrastructure in order to free up and optimize the total capacity.
Both the establishment of new lines, as well as electrification and modernization of existing ones will lead to a larger and more complex protection and control system. Because of their specialized nature, traction power protection and control systems can present challenges.
The complexity here expresses itself in many ways. First, on the technical front it is distinct in developing, engineering and commissioning the appropriate solutions. Second, operationally it is visible during management of a high network utilization, with higher availability, while doing so with fewer human resources. Last, commercially, by the need to adopt solutions that lower the total cost of ownership and allow for easier dependence on third party resources.
Neither are these trends new nor are they unique to the transportation sector. The utility domain has faced and faces many of the same challenges.
Pressure to utilize available resources to the maximum and to reduce personnel required to handle them has always been a key business interest.
Today, a combination of several technologies is creating waves of changes in the utility and transportation power sector:
- Wide-spread communication allows for data to be made widely available, at minimal cost and effort.
- Increase in microcontroller and microprocessor processing capacity allows for complicated applications to be deployed on relatively low cost hardware. This generation of intelligent electronic devices (IED) has reached such a maturity that they are uniformly accepted by the market.
- Continued standardization by international bodies such as IEC and IEEE, particularly in the communication domain, is enabling the consequent data-modelling of the entire power infrastructure.
- Connected asset lifecycle management (CALM) solutions leverage the technology and data they themselves extract into a value of its own. This facilitates orchestration of priority, process and people across an organization, enabling the management of physical assets across the entire asset lifecycle.
With IEDs as the gateway to a multitude of process data, the future of substation automation looks bright. ABB grid automation has the technical proficiency, the entire product portfolio and decades of experience to design, implement, commission and service the digital substation.
Even as the future of digitalization looks bright, we cannot step there in a single substation generation. As our installed base is substantial and knowledge and solutions have to be created over time, a type of device has to exist that bridges the gap between traditional and digital substation.
RER670 bridges that gap. It provides future proof coverage, supporting optimized substation topologies by allowing for functional integration and multi object protection. Moreover, it conforms to the IEC 61850 communication standards and the requirements on network topology and cyber security this communication enablement creates.
At the same time the device supports traditional station topologies. Technology such as precision time protocol (PTP), process bus and station bus are all supported seamlessly with the requirement of today’s installations. Solutions can be mixed and matched within the same IED, such as selecting IEC 60870-5-103 or IEC 61850; conventional CTs and/or merging units, GPS and IEC/IEEE 61850-9-3.
RER670 offers complete future proof coverage.
