Through the renewal of a framework agreement until 2020, DF Núcleo strengthens its position as a benchmark supplier of substation Integrated Control Systems (ICS) for the transmission network operated by Red Eléctrica de España (REE).

The agreement covers the supply and set-up of over 10 Substation Automation Systems (SAS), meaning that DF Núcleo would have more than 120 automated substations in Spain. The company will use a version of the SHERPA C5000 system, adjusted to meet the requirements of REE, to develop these projects.

Through the execution of this agreement, DF Núcleo will have more than 120 automated substations in Spain
The technology solution supplied by DF Núcleo is based on the SHERPA C 5000 SAS system, developed in-house, which combines the Company's extensive substation control experience with the latest advances in automation.

The SHERPA C5000 supplies information on the entire substation to operating stations with the purpose of allowing operations to be carried out in greater safety, avoiding operating errors and even streamlining circuit replacement in case of unforeseen events.

The system consists of the following components:
  • System Operation Interface (SOI): a substation operation and supervision system including robust and reliable safety components.
  • Substation Control Centre (SCC): this unit is used to access data and operate the substation from the Power Control Centre, using remote control protocols (IEC60870-5-101, IEC60870-5-104 or DNP3.0).
  • Local Control Unit (mULC): control equipment fitted with a graphic interface that performs bay control functions. This equipment can also be integrated with third party equipment.
  • An integrated management and maintenance system, consisting of substation engineering and maintenance tools.

Evolution of the system
The SHERPA C5000 has been designed in accordance with the specifications of the IEC-61850 standard, which regulates and promotes the interoperability of equipment installed in substations. It also sets out steps to be taken to achieve a Digital Substation, mainly by incorporating a process bus to replace the copper point-to-point connection of all components.

DF Núcleo is currently working on pilot programmes to develop the prototype that will define how all ICS systems nationwide will be renovated, based on the IEC 61850 standard, Ed. 2. In this sense, the company already has a portfolio of products certified to this standard:
Local Substation SCADA: iSHERPA
I/O acquisition equipment, bay controllers and gateways: SHERPA R5000, SHERPA R5000 Compact and SHERPA R5000 Compact+
