SSC600 SW is the virtualized version of the Smart Substation Control and Protection SS600 device. In 2018, ABB introduced this revolutionary approach to protection and control (P&C) in distribution networks, where all the P&C functionality is centralized into one single device. One SSC600 device can handle the tasks of 30 protection relays. Centralizing this functionality in the substation reduces network complexity and supports optimal, lifelong asset management and up to 15 percent savings in substation life cycle costs.
Why virtualization? There are many reasons why virtualization is increasingly becoming standard practice for IT architecture for businesses around the world. With virtualization, one server can become many virtual machines and replace the traditional ‘one computer, one application’ model. As users can merge more functionalities onto fewer physical devices, they are able to reduce the amount of space and administration needed. In other words, virtualization allows operators to get the most out of their hardware, while also cutting costs and achieving greater efficiency.
ABB introduces SSC600 SW
Customers can now choose SSC600 SW and are no longer tied to specific hardware allowing them to optimize their IT infrastructure. With many systems accommodated on one platform, they can reduce the number and type of devices and hardware in substations. This greatly simplifies performing maintenance activities. The inherent separation of functionality from hardware (virtualization) allows integrated, system-wide upgrades and additional functionality, without introducing the need for new hardware. As an example: an SSC600 device can protect 30 bays, whereas with a virtualized approach, customers can install multiple SSC600 SW instances on a single computer for even bigger systems.
Further, with virtualized functionality, a substation owner can replace different kinds of old equipment with the same type of new equipment. This substantially reduces the amount of knowledge required to maintain the substation because of the smaller amount of hardware variants.
To create a robust power system protection and control solution that provides the flexibility and enhanced resiliency necessary to face increasingly complex grids, SSC600 SW supports Linux KVM and the VMware Edge Compute Stack platform featuring ESXi 7.x or later as virtualization environments and runs on Intel® Xeon® Gold processors to ensure real-time performance.
“The energy landscape is undergoing rapid and fundamental changes triggered by shifts in regulations to accelerate the green transition as well as immense advancements in technology,” said Sami Raitakoski, Global Product Group Manager at ABB.
Further enhancements to SSC600 with feature pack 4
Since the initial launch of SSC600, ABB has regularly introduced new features and functionality to meet the increasing demands for more detailed information on distribution network behaviour and performance. With the launch of SSC600 SW, ABB also released a new feature pack, FP 4, in which several enhancements and additions become available. Highlights include a re-developed user interface, which greatly improves visualization, helping you to perform the right actions with ease. To ensure robustness, the core tools behind the user interface have been replaced with new technology.
In response to customer feedback, the disturbance recorder function has been further enhanced and can now support longer recording times and offers more storage space for the recordings. And new functions have been added, including fuse failure supervision for increased robustness. This function is used to block the voltage measuring functions when a failure occurs in the secondary circuits between the voltage transformer and protection relay. Another addition is protection for shunt capacitor banks.
Due to their critical role in the power system, protection devices must be acceptance-tested prior to being taken into service and periodically thereafter to ensure reliable performance. To further facilitate testing during all phases of the protection system’s lifecycle, FP 4 also introduces support for simulation as defined in the IEC 61850 standard.
