Electrical solutionsfor fossil fuel and

nuclear power plants

Fossil fuel and nuclear power plants are today’s major source of electricity as they offer superior availability and cost-effectiveness.

You need efficient solutions to manage and optimise your electrical system’s entire life cycle – from design and optimal operations, to maintenance and upgrades – to avoid failures which could result in the loss of revenue or penalties.

A power plant’s electrical power system delivers the produced electricity to the grid. It also supplies the power which is crucial to running the plant itself. This dual-function electrical infrastructure is vital to all power plants.

The construction period of these large, complex power plants is also critical. They have to be brought on-line as fast as possible while maintaining a high safety level and respecting the environment, without jeopardising equipment quality and system reliability.

To meet all these challenges, you can turn to Alstom Grid. We are a committed partner who know how to supply electricity to your plant and deliver your electricity to the grid, whatever the type of power plant you operate - conventional, gas or nuclear.

Meeting the challenges...World electricity demand continues to grow. The total electricity consumption will increase by 66% between 2008 and 2030. In developing countries, the growth can be doubled.

Coal-firedCoal is the predominant source of electricity around the world (34% of electricity generation), far ahead of nuclear or gas. This is because the process of generating electricity from coal is well known and, of course, coal is inexpensive and plentiful. Coal-fired power plants are large, complex projects in which the electrical systems play a key role in timely commissioning and long-term availability.

Alstom Grid engineering and project management expertise ensure smooth management of the electrical systems supply and installation.

Whatever type of power generation...

GasBecause of its low capital cost and limited environmental impact, the share of natural gas in global electricity generation has grown rapidly. It is projected to reach 22% by 2030. Open or combined-cycle power plants often have a short construction schedule. Here again, the electrical systems contribute substantially to plant rapid commissioning and its long-term availability.

Alstom Grid engineering and project management know-how will help you streamline the supply and installation of the necessary electrical equipment.

NuclearAround 14% of the world’s electricity comes from nuclear power plants. As nuclear power emits no greenhouse gases, and uranium resources are essentially inexhaustible, this clean generation is expected to expand significantly in the coming years, buoyed by climate change concerns and the rising cost of fossil fuels. The electrical systems of nuclear power plants are subject to a very stringent product qualification process.

Alstom Grid has vast experience in supplying equipment to nuclear power plants, particularly in China, France and Germany.

The electrical balance of plant systems (eBoP) supplies vital power to run the plant, supplying power to all plant auxiliaries. It is key to the efficient, reliable power plant operation. Alstom Grid can offer you complete eBoP solutions for all power plant types. Using innovative electrical power applications, we can build and maintain a safe and efficient power system you can depend on, day in, day out.

eBoP – the arteries of power plants...and

Protection and control equipmentThe Alstom Grid range of protection relays offers a comprehensive solution for all power train and eBoP applications covering generator, transformer, feeder, motor, and busbar protection applications. MiCOM P40 protection relays have a large number of years of experience in the field with over 100,000 MiCOM P40 series relays sold worldwide since 1999.

numerous integrated communication protocols allow easy interfacing to substation control or SCADA systems. From simple wired serial buses to Ethernet station and process bus architectures with IEC61850 MiCOM protection, Alstom Grid has the solution.

The MiCOM P34x generator protection range of relays provides protection for a wide range of applications from small generator and generator-transformer applications to large generators.

The top range P345 model includes a comprehensive range of protection required for large generators such as pole slipping, 100% stator earth fault using 3rd harmonic voltage and low frequency injection methods. The P346 is an economical solution for smaller generators or generator transformer protection, providing differential protection of the generator and transformer, plus standard generator and transformer protection functions in one box as well as transformer condition monitoring features, such as transformer top oil and hot spot temperature, through fault and loss of life functions.

For the step-up and auxiliary transformer protection the P64x transformer protection range is available, which offers differential protection for 2, 3 or 5 winding transformer and generator-transformer applications, plus all the standard transformer protection and condition monitoring functions required.

Power transformersAlstom Grid is a world leader in power transformers.

Generator step-up transformers are constantly faced with voltage changes, either due to load rejection or switching operations, followed by generator over excitation. They must also withstand over-loads, so winding gradients must be adjusted and the cooling capacity remain sufficient. The high rated currents require absolute control of the magnetic field inside the tank to avoid localised overheating of associated metallic parts.

All of these situations are taken into account during the design process of your unit. Generator step-up transformers require very specific know-how, production equipment and testing capabilities, as high or very high voltage and rated power are often required. We have supplied step-up generator transformers up to 1,100 MVA 420 kV (three-phase) and 245 MVA 765 kV. Over and above standard transformers, we can provide you with hermetic transformers, boasting a substantially longer service life. Our transformers can be filled with biodegradable vegetable oil on request.

Alstom Grid offers innovative, sustainable, high quality service solutions in order to optimise your electrical infrastructure, heighten your return on investment and support your assets life cycle.

Power system analysis and engineeringTo plan new installations or to improve the performances of existing power plants through an upgrade or an expansion, our network Consulting experts support customers in analysing, specifying and designing network systems to meet customer specific requirements. The conducted studies allow them to take the appropriate decision to set up an effective network.

Asset management and maintenanceWith the goal of improving efficiencies and downtimes while lowering costs, operators have to get the most of their equipment in the long term. Alstom Grid supports its customers in this challenge by providing long Term Maintenance, a set of tailored expert services executed on a multi-year partnership. Our partnership is comprehensive to fit with specific needs. It can include strategic spare parts management, scheduled inspections (oil analysis, vibration measurements, thermographs etc.) and condition-based maintenance with remote monitoring systems.

Renovation, Modernisation and Extension (RME)High voltage substations and generator circuit breakers are critical for a power plant’s reliability and network performance. After decades of operations, operators may foresee risks of increasing failure rate. They may also address the need for evolving power demand or the need for standard or technological enhancement. Service experts answer this challenge by providing rME to give a second life to their equipment. It can include complete substation refurbishement, equipment replacement, transformer mid-life overhaul, GCB forklift upgrade, electrical ratings increase and add-on technologies such as condition monitoring.
