During the second quarter of 2008, Efacec carried out an important set of automation systems commissioning, for several clients in Portugal, of which we can highlight the following ones:
|
|
REN, Estarreja Substation |
| |
Recently, Efacec has concluded the works relative to the expansion of an Automation System for the Estarreja Substation (220/60 kV) of REN (Redes Energéticas Nacionais), Portugal. |
| |
The scope of supply for this substation, of the turn-key type, included one transformer bay of 220/60 kV, with the following systems:
- Automation System based on CLP 500SCC
- Transformer Protection System, from third parties |
| |
The Estarreja substation is integrated into REN’s transmission network, in the Centre Region of Portugal, with a 220 kV triple bus-bar topology with a bus-coupler and bypass, and a 60 kV double bus-bar topology with a bus-coupler. |
| |
The substation composition is the following one:
- 4 Lines of 220 kV
- 1 Bus-coupler bay of 220 kV
- 4 Transformers of 220/60 kV
- 10 Lines of 60 kV
- 1 Bus-coupler bay of 60 kV
- 2 Capacitor banks |
| |
The Efacec automation units communicate with the UC 500E central unit (in a hot standby redundant configuration) through the IEC 60870-5-104 protocol. Both UC 500E communicate with the National Dispatch through the IEC 60870-5-101 protocol. For the four transformers it was implemented the automatic voltage regulation function. |
| |
The installed solution is distinguished by its technological component, defined according to REN’s specification, which demanded a high technical complexity system. All systems are functionally compatible with the solutions already implemented by Efacec in previous REN’s projects. |

|
GENERG, Trancoso Switching Station (according to the IEC 61850 standard) |
| |
Recently, Efacec has concluded the implementation of an Automation System for the Trancoso Switching Station (60 kV), for GENERG, Portugal. |
|
| |
The Trancoso Switching Station is located next to the Trancoso Wind Farm (with a total power of 28 MW), from which a 60 kV line has been implemented to transport the produced power up to the EDP network. |
| |
GENERG is a company operating in the renewable energies field, aiming to construct and operate electric power production assets from renewable sources. |
| |
The supplied system is based on a distributed architecture, supported by the CLP 500SCC substation automation platform, constituted by the following hierarchical levels:
- |
Central unit – central processing module, which basic functions are the management of communications with the upstream hierarchical centre, the system database management and the management of communications with the acquisition level |
- |
Bay protection and control units – integrating substation automation functions, distributed human machine interface and a communication local network |
|
| |
The communications between the central unit and the bay units, as well as those between several bay units, are carried out through an optical fibre local network, according to the IEC 61850 standard. The bay management units also assure the automation and interlocking functions. |

|
EDP Distribuição, set of 3 Substations (Inha, Sousa, Monserrate) and Polipropigal Switching Station |
| |
Recently, Efacec has concluded a set of works in the field of distribution substation automation for EDP (Energias de Portugal), relative to the installation of automation systems for several substations, namely Inha (60/15 kV), Sousa (60/15 kV) and Monserrate (60/15 kV), and for the Polipropigal (60 kV) switching station. |
| |
The scope of installations, of the turn-key type, included the following systems:
- Automation systems based on CLP 500SCC
- Protection systems, by Efacec and third parties |
| |
Integrated automation systems were installed in the following facilities:
| - |
Inha Substation (60/15 kV), with the integration of digital protections, by Efacec |
| - |
Sousa Substation (60/15 kV), with the integration of digital protections, by Efacec |
| - |
Monserrate Substation (60/15 kV), with the integration of digital protections, by Efacec and third parties |
| - |
Polipropigal Switching Station (60 kV), with the integration of digital protections, by Efacec |
|
| |
The Efacec solutions are based on distributed architectures, supported by the CLP 500SCC automation platform, integrating digital protections communicating with each other in a peer to peer basis. |
| |
The architectures proposed by Efacec allow to obtain lower costs concerning installation, tests and maintenance, which makes the solutions more attractive, both from technical and investment point of view. |
| |
With these commissioning works, Efacec reinforces its leadership position in Portugal, within the scope of supply of sophisticated automation systems for distribution substations and switching stations. |
| |

| |
|
EDP Produção, set of 14 small hydro Power Plants |
| |
Recently, Efacec has concluded a set of installations relative to remote control systems for small hydro power plants, for EDP Produção. |
| |
The scope of supply, of the turn-key type, included:
- 14 Systems based on the CLP 500FEP platform, with diskless and fanless technology
- 1 Duplicated SCADA system, in LINUX version, based on SCATE X GREEN, for the Control Centre |
| |
The systems installed in the power plants work as gateway of several equipments existing in each power plant, in the scope of a remote control solution for 14 small hydro power plants. The Control Centre implementation allows to carry out the remote control and management of these power plants.
|
| |
This set of important implementations is recognised as a sign of trust, by EDP, concerning the supply of remote control and automation systems by Efacec, for hydro power plants and small hydro power plants. The offered solutions are characterized by their high flexibility, performance and availability. |
