Requirements and Trends for Soccer Stadiums
In the years between 1890 and 1940, the construction of soccer stadiums boomed for the first time, when soccer became a mass phenomenon in many countries in the world. Some of these stadiums, which are now more than a century old, are still being used today.
The second construction wave followed at the end of the Eighties, when it was found that the architectonic and technical equipment of many old stadiums could not be defended any more. This trend for moderniza-tion and for a new construction of stadiums continues unabated to this date.
Operators, planners and architects have risen to the challenge and designed stadiums that meet modern requirements and provide the utmost of safety for the visitors. Last not least to satisfy the FIFA regulations, the safety of all people in the stadium has top priority in all decisions.
The technical “heart” and core of all electricity powe-red facilities in a stadium is the electric power distri-bution system. If this system functions reliably and efficiently, all electrical systems are on the safe side. The concepts applied to ensure this must meet the comprehensive specifications and regulations of international committees. These include
• the IEC (International Electrotechnical Commission),
• the IAAF (International Association of Athletics Federations),
• the FIFA (Federation of International Football Associations),
• and the IOC (International Olympic Committee).
These specifications also include that operation of the systems applied be uninterruptible.

Energy Efficiency in Sight
The technical requirements on the amenities of modern soccer arenas are high, which usually goes in line with a high demand of electricity. Floodlighting, for example, consumes lots of electricity, in addition, electricity is required for air conditioning the buil-dings, for lighting, catering, lawn heating and for supplying the media. World championship stadiums consume 3.5 million kWh of electricity on average and an additional 4 million kWh of heating energy per year. In addition to the power demand for operating the actual games venues, numerous facilities for media coverage must be power supplied during big sports events.
The FIFA soccer world championship is the sports event with the largest media attention worldwide. The top-priority goal during events is an uninterrup-tible and reliable power supply for all media facilities (TV broadcasting) and for the floodlights. Field light-ing, necessary for the new high-definition television standard (HDTV), normally consists of high-intensity gas discharge lamps, which are extinguished during power failures and can only be reignited a few minutes later. This means that TV broadcasting of the event would be interrupted during a power failure.
The delay or cancelling of an event owing to a power failure is not acceptable. Careful planning of the power supply system is therefore of utmost importance. When the normal power supply fails, operation must be ensured by an emergency power supply system, for example by means of generators and uninterruptible power supply systems (UPS).
With Green Goal™, the FIFA has developed a concept for the sustainable environmental protection of soccer stadiums. The main targets of the program are the reduction of drinking water consumption, the avoi-dance or reduction of waste and the reduction of total energy consumption. These measures shall contribute to neutralizing the global warming gas output in its climatic effect. The program was first used during the FIFA soccer world championship in Germany 2006™ and shall be extended to all FIFA events.
Energy-saving measures form an integral part of the FIFA‘s Green Goal for planning and building a new stadium. This includes the use of regenerative fuels, such as solar energy by installing photovoltaic systems, insulating the outer building shell to reduce power losses and the use of a central building management system in order to control building functions efficiently. The use of variable-speed drives and energy-saving motors for fans in ventilation sys-tems, or for circulating pumps in heating systems is a further leverage for reducing energy consumption.

The Technology Platform:Totally Integrated Power
Integrated power distribution from the infeed to the consumer
Totally Integrated Power™ (TIP) refers to integratedelectrical power distribution in commercial and industrial buildings; from the medium voltage supply fed in by the utility company right up to the final electrical consumer.Totally Integrated Power is underpinned by an array of helpful tools and support for accurate design, dimensioning and configuration of electrical power distribution within buildings. A coordinated product and systems portfolio for the construction of these systems is rounded off by standardized interfaces between the system components and the higher-level human-machine interface systems as well as for the connection to control and management systems.In this way considerable savings can be made acrossthe whole project cycle – from the planning stage,installation and start-up right through to operation –in both new buildings and renovations. The necessaryinvestments in the sports arena’s electrical infra-structure can be optimized in line with demand and also with subsequent operating costs. This optimization potential represents significant added value for everyone involved in the project
Optimum planning for cost- and time-effective solutions
An optimally dimensioned power distribution systemis a key economic factor for sports arenas. Unused capacities cost money. The tried-and-tested TÜV-certified SIMARIS® design dimensioning software by Siemens provides electrical engineering consultants with an indispensable tool for planning the electrical network for a new or renovated sports arena.SIMARIS design brings many benefits, including sim-pler network calculation and selectivity verification.The software also recommends suitable coordinateddevices from the integrated Siemens power distribu-tion product portfolio. Electrical network upgrade reserves can be incorporated right from the planning stage to allow for later changes of use or extensions of a sports arena.Electrical engineering consultants can make time savings of up to 100% by using SIMARIS design for the various network planning stages. Thereafter, SIMARIS configuration supports power distribution board manufacturers and installation contractors in the configuration of low-voltage power distribution boards. ALPHA SELECT, on the other hand, makes the selection of suitable distribution boards fast, safe and easy.In addition, Siemens also provides advice and supportfor electrical engineering consultants through virtually all the planning stages.

Schematic Outline of a Power Distribution System for Soccer Stadiums
The reliability and availability of power supply for all media facilities (TV broadcasting) and for flood-lighting are besides the protection of persons the most important requirements to the electric power supply in a stadium.
To be compliant with the FIFA Guideline 2007 (“Football Stadiums: Technical recommendations and requirements”) an interruption, impairment or cancellation of an event owing to a power failure is not acceptable. The floodlights supply and TV broad-casting and the supply of all media consumer (OB van, TV studio, cameras etc.) in conjunction therewith must be ensured without interruption by the stadium operator according to this guideline.

As this block diagram shows the required reliability of supply for the individual loads is oriented towards their importance
• UPS loads: unimpaired maintenance of the reliability of supply during the match owing to an uninterrup-tible power supply (UPS).
• SPS loads: In an emergency, the safety of persons is maintained by a so-called safety power supply (SPS). In practice this is also often safeguarded by the UPS.
• RPS loads (RPS = redundant power supply): important consumers which are often connected to at least one redundant supply, in the event of a power failure a short interruption is, however, tolerated.
• NPS loads (NPS = normal power supply): These “normal” consumers are of no particular importance, they can be connected to the normal mains. In the event of a fault, the temporary outage of these consumers is tolerated. Alternative supply via emergency generators is not provided for these consumers.
The following schematic and principal diagram outlines the most important components of electric power distribution in a stadium and their interplay to ensure an optimal reliability of supply and operational safety of electrically operated facilities and equipment. This power distribution concept can, of course, be adapted to the specific requirements of a particular stadium:

There are two possible operating modes for diesel generators:
They could be run up in the event of a fault and connected into supply or they can run in parallel to the normal grid during a sports event right from its start, which shortens connection times considerably. A cost-effective variant would be the use of mobile generators which are only available during a sports event.
Reliability of supply could be further increased by a combination of generators and UPS systems. In any case, this ensures uninterruptible continued supply of the most vital power consumers, independent of the fact whether generators are connected into supply or not, and the generators basically offer a second redundant power supply.
UPS systems of a high-quality design provide the additional advantage that they can balance short-time voltage or frequency fluctuations; when the higher-level network fails, an immediate changeover is made to the internal batteries.
During other non-sports events it is sufficient to run up these emergency generators (diesel generators) only when needed, as there is sufficient capacity from the UPS systems during the bridging time, which ensures trouble-free continued supply of the safety-supply loads.
The FIFA guideline emphasizes a clear separation and distinction between UPS loads and SPS loads in network design. The same also applies to the design of the associated UPS systems
The stadium is supplied with 10kV by two separate medium-voltage grids of the local utility company (e.g. substation North and South city). They feed into the transformer substations at the medium-voltage level.
Power supply is divided into load center locations (e.g. medium-voltage substations East and West). The low-voltage main distribution systems (LVMD) are assigned to the transformer substations and divided into LVMD-NPS and LVMD-SPS. There is a coupling between the normal and the safety supply side which is equipped with interlocking mechanisms to prevent undefined network operation situations.
If one of these higher-level supply networks breaks down, an emergency connection is closed at the low-voltage level between the LVMD-SPS West and East to ensure continued operation of the system. If appro-priate, this extra-ordinary operating state requires automatic load shedding of the normal mains loads.
Emergency power supply is provided at the low-voltage level by a diesel emergency generator in the substations West and East, which ensures continued uninterrupted operation of essential power consumers such as floodlights and media facilities in order to comply with the FIFA requirements.
The systems suitable for emergency power supply are diesel generators and also – for a short period of time – UPS systems.
It is especially field lighting where emergency power supply is of vital importance. Otherwise high-intensity gas discharge lamps (HID lamps), which are frequently used, would extinguish during a voltage break-down. The live broadcast of the match on TV would be interrupted and it would take a couple of minutes until the full illumination would be available again.

Visualization of Power Distribution in Building Management Technology
In order to visualize operating states and fault messages, and to run the venue profitably, interfa-cing to a building management system is required. To do this, the entire power distribution system ranging from the medium-voltage level to the low voltage level is designed to include the option for passing and receiving information via bus systems. From the power feed-in to the loads, the energy flow can thus be established, visualized and also controlled, if necessary. This is an essential prerequisite to optimize energy cost. In order to interface peripheral equipment and to transmit data to the building management system, standardized bus systems with fiber-optic cables are used (PROFIBUS DP and Industrial Ethernet).
The DESIGO building management system helps operate the sports venue efficiently and supports in optimally controlling room conditions, e.g. in the VIP lounges and the catering area. With DESIGO, the sports venue operator has a great variety of comfortable access and control options at hand to operate heating / ventilation / air conditioning. An additional feature is the visualiza-tion and control of the entire power distribution system.

Medium-voltage Switchgear
Today, gas-insulated medium-voltage switchgear is state-of-the-art for safe operation of a sports stadium. The 8DH or NX Plus C product series are particularly suited for sports stadiums.
All systems have been type-tested in compliance with the latest standard IEC 62271-200 / VDE 0671-200 and they meet the high requirements of the arcing fault qualification.
In order to reduce transmission losses and to attain a profitable solution, power is supplied to the building from the medium-voltage grid of the local power utility company. In the building, a medium-voltage utilities substation with transformer feeders is used for this purpose. The normal voltage level is 10 kV. With the same power output, the specific losses are significantly lower at the medium-voltage level than at the low-voltage level (230/400 V). The medium-voltage utilities substation or further substations should be erected directly in the load centers of the building, if possible.
In its basic version, medium-voltage supply for a stadium consists of a utilities substation, trans-formers, possibly a medium-voltage ring with the associated substations. Safety is ensured by the integrated medium-voltage circuit protection technology.
The utilities substation contains feed-in panels for power feed-in from the utilities company, a load transfer panel for stadium supply, a metering panel to record consumption and directly fed transformer outgoing feeder panels with switch-disconnectors for connecting the central low-voltage main distribution system.
The medium-voltage switchgear station consists of the following enclosed and panel-wise partitioned compartments:
• Busbar compartment
• Circuit-breaker compartment
• Cable connection compartment (if available)
• Low-voltage compartment
Distribution Transformers
GEAFOL transformers by Siemens cover a power rating from 50 kVA up to 40 MVA and operating voltages up to 45 kV. Built up from a special combination of foils and tape windings made of aluminum in conjunction with a cast-resin insulation, Siemens GEAFOL transfor-mers provide the utmost of safety.
Besides excellent electrical, mechanical and thermal properties, the specific mixture made of epoxy resin and silica flour as a shell ensures a usability which is environmentally friendly, weatherproof and also requires no maintenance.
In low-loss design, these transformers are also suitable for economical long-term use yielding simultaneous cost savings thanks to lower internal magnetization losses.
16
Type-tested Low-voltage Switchgear/ Distribution with Central Reactive Power Compensation In sports stadiums, a power-optimized technology is used, featuring a high installation density both with circuit-breaker-protected (Siemens SENTRON 3WL / 3VL) and fuse-protected device technology (Siemens 3N). With its completely modular design and fully enclosed functional compartments, the SIVACON S8 low-voltage switchboard by Siemens ensures the maximum of safety for man and machinery and limits the effects of arcing faults and fault propagation to a minimum in case of failures. Its safety and quality is verified by typetesting and arcing fault tests as well as by typetested interfacing to busbar trunking systems.
Central reactive power compensation is used for a more efficient utilization of the electrical energy. Important economic advantages are, on the one hand, the saving of energy cost and on the other hand the more costfavorable dimensioning of the distribution system. The current load on the distribution is substantially cut, power losses are reduced and thus electrical energy is saved.
The following installation technology is available:
• Circuit-breaker panel with SENTRON 3WL up to 4,000 A or 3VL up to 1,600 A
• Universal installation technology for cable feeders up to 630 A in fixed-mounted and plug-in design
• 3NJ6 in-line design (plugged) for cable branch lines up to 630 A in plug-in design
• Fixed-mounted panel (front cover) for cable feeders up to 630 A and modular installation devices
• 3NJ4 in-line design (fixed-mounted) for cable feeders up to 630 A
• Reactive power compensation up to 500 kvar
17
Busbar Systems for Power Distribution and Power Transmission Busbar trunking systems are used for power transmission and distribution, they are the link between the transformer and the power consumers. Transmission losses owing to long cable routes must be reduced for economical reasons. Busbars are increasingly replacing cables, in particular for high currents, where a cable would mean the wiring of several conductors, where installation is very difficult and a high fire load is created.
Busbars trunking systems can be used profitably and ensure reliable and sustainable power supply for years.
Profitable, highly available power supply in the smallest possible amount of space is essential for a sports stadium. Such a power supply requires the maintenance of functions for emergency power in the event of a fire, a high degree of flexibility in case of subsequent changes of use in the normal power supply system and a low fire load.
The following busbar systems are applied for power transmission in a sports stadium:
• BD2 from 160 A up to 1,250 A for load center supply in the stadium
• LD up to 6,300 A for power transmission between the transformer substations
Subdistribution Systems and Distribution Boards In a stadium, low-voltage subdistribution systems are first of all used for decentralized power distribution. Depending on their purpose and location of use, distribution boards may be used or required for surface-mounting or flush-mounting, in stand-alone or wall-mounted versions, or as busbar trunking systems, and they may have to provide a certain degree of protection. In their type-tested or also partially type-tested versions, low-voltage subdistribution systems by Siemens are a synonym for the highest degree of safety. The following distribution boards are applied
in a sports stadium:
• ALPHA 160 – DIN wall-mounted distribution boards up to 160 A
• ALPHA 400 – DIN wall-mounted distribution boards up to 400 A
• ALPHA 630 – DIN wall-mounted distribution boards up to 630 A
• Special designs: line-up cabinets, meter cabi-nets and insulated distribution systems
