Substation Automation System (SAS)
With the SHERPA C 5000 system, Núcleo provides a complete solution  for  remote  control  of  Substations,  combining  its  vast  experience   in   remote   control   of   Electricity   Substations   with the  most  recent  trends  in  Substation  automation:  International Standard IEC-61850.

Standard IEC-61850 provides a new perspective for the automation of Electricity Substations, not only from an operational point of view, but also regarding maintenance and engineering tasks in the substation.

The main objective of this standard is to enable interoperability between different equipment manufacturers. In order to achieve this purpose, the standard  supports  commercial  communication  technologies  based  on TCP/IP and the specification of an information exchange system between 
substation devices. Both components provide the user other additional benefits: reduction of cabling in the substation, reduction in start-up time and improve reliability of the final system.

From the point of view of distributed systems based on Client-Server models,  Standard  IEC-61850  defines  a  common  data  model  (IEC-61850-7), the specification of communications between the IEDs of the Substation  (IEC-61850-8)  and  a  single  communication  language  for exchange of information between the engineering tools (IEC-61850-6).

The SHERPA C 5000 is made up of the following elements:
  • SCADA SHERPA. This is the substation's operating and monitoring system and includes safety, robustness and lasting reliability features for control centres based on software applications developed by the Núcleo.
  • SHERPA C 5000G. A unit that enables access to the data and to operate the substation from the Electrical Control Centre using traditional remote control protocols.
  • SHERPA R 5000. Control unit equipped with graphical interface that performs bay control functions. It also enables integration with conventional third-party units that are not compatible with the system's standard.
  • Integrated management and maintenance system made up of tools for substation engineering and maintenance.
Núcleo has proven experience in the supply of Substation Automation Systems. In addition to the extensive experience accumulated in Spain, Núcleo has more than 100 systems in place at the international level in Honduras, Venezuela, Brazil, India, Morocco and Mexico. In the latter country, the Company launched the first systems under the IEC 61850 standard in 2016. In addition to conventional transformer substations in the electrical cycle, Núcleo worked with step-up substations for wind farms and with railway substations.
