MV/LV Power Distribution and Centralized Facilities Management for Estádio de Luz
As Euro 2004 host country, Portugal is welcoming visitors in grand style to ten new stadiums, in Porto, Braga, Coimgra, Faro, Leiria and two in Lisbon. Much more than simply venues where spectators sit and watch, modern-day stadiums have become veritable works of art.
Estádio de Luz, the “gem of Euro 2004”
The 65,000-square-meter arena has 65,400 seats and two giant 48-square-meter screens. Electrical power is of course indispensable to the functioning of this vast facility, requiring some 115 kilometers of electrical wiring to supply stadium utilities, including lighting, HDTV and radio transmission, sound systems, safety, air-conditioning, hot water production, smoke evacuation, and food and beverage outlets. All this demands 9 MVA of installed power, equivalent to the power consumption of a city of 25,000 inhabitants!
All these electrical systems had to be designed to meet the double challenge of safety and uninterrupted service as stipulated by UEFA, the European Football Association. The problems to be resolved concerned deployment of resources to avoid any interruption in the electrical power supply, coupled with complete automation of all the operating processes.
Backup power and security power supply essential for public facility are provided by electrical generators linked to a battery of uninterruptible power supplies (UPS). To further strengthen service continuity, total selectivity has been configured between all protection devices on the main EDP supply substation and the distribution switchboards. Selectivity is enhanced by the use of standard products throughout the facility.
Configuration of the MV/LV network and operating modes are controlled by the facilities management system, which comprises Telemecanique Premium PLCs and remote Momentum I/O on an Ethernet TCP/IP network. Monitoring is performed by four substations equipped with Monitor Pro software. The system displays animated graphics for operating technicians showing the entire network and detailed status information (MV/LV cubicles, circuit breakers, actuators, etc.), alarms, failures, operating times, plus voltage, intensity and power consumption data. A laptop can be plugged into any point in the Ethernet to quickly troubleshoot the system and implement corrective action.
To successfully deliver this exceptional project, Schneider Electric Portugal coordinated a consortium team led by Philsystec. Philips Lighting was the lighting contractor and Schneider Electric installed electrical systems in partnership with Marobal (engineering and design), Monofásica and Gerco (contractors).
The comprehensive electrical power distribution system and facilities management system combine to guarantee high reliability, safety and availability for all facilities. What’s more, the facilities management system allows easy control and significantly simplifies maintenance operations.
