TRANSCRIPT
CCNS for ENDESA – Chile
ENDESA-Chile is the largest privately owned electricity generation company in Chile measured by installed capac-ity and one of the largest electricity generation companies in Latin America. They have chosen ABB’s Converged Corporate Network Solu-tions also for their mission critical communica-tion infrastructure.
Converged Corporate Network Solutions for the RALCO-Projects make use of latest Utility Communication equipment
Reference
About ENDESA –Chile & the RALCO-project
ENDESA-Chile owns and operates about twenty generation facilities in Chile with a total installed capacity of 4 GW, which is about 40% of the country’s power generation. About 70% of the plants are hydroelectric, the remaining stations are oil or gas fired thermal installations.
Due to the extremely stretched topology of Chile, the electricity supply system is divided into three regions (North, Central, South). The new Ralco dam on the Biobio river is under construction to cover the growing energy demand in the central part. When fully operational, it will generate about 570 MW.
Growing Communication Needs
The related infrastructure also needs to be strengthened with the growing energy pro-duction. New substations and control centers have been built to increase the availability of the power supply in the southern regions of Santiago de Chile. Therefore, the partly existing utility communication systems also had to be extended. The following are the major requirements:
Optical STM-1 and PDH connections between Charrua and Central Ralco stations
60 Mbps IP connectivity between the SCADA-sites in above stations and Antuco for operational & office traffic
Optical links shall be repeaterless, even for distances of more than 140 km
2 Mbps IP-based video-surveillance Fully redundant teleprotection-signalling
solution Standard & Hotline telephone services
One communication network
Implemented Solution
Twelve sites for communication installations were identified and realised. Figure 2 shows some of the network details such as:
All SDH and PDH optical links are 1+1 protected, based on ABB’s versatile uni- versal FOX-family multiplexer
Additional system redundancy is added by integrating all stations in a 2 Mbps ring structure, closed via existing radio-links
Teleprotection-signalling is sent as main- path over the 1+1 PDH links, using the TEBIT-card as teleprotection-device, integrated in the FOX
Teleprotection-signalling has a dedicated back-up – path via Power Line Carrier (PLC) using ETL580 in combination with ABB’s latest protection equipment NSD570
The 145 km STM-1 stretch can be made without repeaters by using ABB’s LHC550 long-haul optical devices
High IP-bandwidth combined with TDM- traffic can be achieved by using AXX155E, which multiplexes E1- & IP-signals in a seamless way into STM-1
An IP-backup path is established by FOX LAWA4 card, which routes priority IP-traffic via alternative radio paths

“Communication is an importantpuzzle part for the overall success of the
RALCO-project. Reliable delivery ofrevenue generating electricity is notpossible without a state-of-the-art
underlying communication infrastructure.Cost pressure does not allow us to run
dedicated networks for the variousapplications; with ABB’s ConvergedCorporate Network Solutions we areextremely well prepared to serve the needs of the various interest groups,
such as SCADA-, teleprotection- & alsoIT-crews with their increasing bandwidth
requirements. By using ABB’s fiberoptic long haul technology an othertarget could be achieved: no costly
repeater stations for communicationmeans are needed. Together with an effi-
cient network management tool, thishelps to cut operational costs further.”
