EDF selects Symphony Plus for French coal-fired plants

2013-03-27 - EDF, one of the world’s leading electric utilities, has selected ABB to supply Symphony Plus total plant automation systems and long-term service support for three 600 MW units at the Le Havre and Cordemais coal-fired power plants in France.

EDF operates 23 fossil-fired power plants in its home market, France. Together the plants produce around 16.9 terawatt-hours (TWh) of electricity annually. Although most of EDF’s fleet in France are nuclear power plants, coal remains part of the company’s long-term strategy and energy mix.

Recently, EDF initiated an extensive program to modernize Le Havre 4 and Cordomais 4 and 5 units to extend their operating life by 20 years to 2035. These three units are the largest coal-fired units in the EDF fleet and were built to an identical design in the early 1980s. Each has a generating capacity of 600 megawatts (MW).

The modernization program is comprehensive and complex in scope, involving the revamping of electromechanical and process equipment, as well as the replacement of obsolete distributed control systems with state-of-the-art Symphony Plus total plant automation systems.

The Symphony Plus solution for each unit consists of a distributed control system, turbine control and protection, S+ Operations, which is an intuitive easy-to-use human machine interface (HMI), and a process optimization package for which ABB is also offering performance guarantees. ABB is also supplying a Symphony Plus simulator for operator training and process simulation.

ABB is responsible for design, engineering, installation, commissioning and training, and will install the new Symphony Plus systems during scheduled annual shutdowns over a four-year period ending in 2016.

One of the highlights of the EDF-ABB collaboration is the 21-year maintenance contract that the two companies have signed, in which ABB will provide corrective, preventive, adaptive and remote maintenance for all three units.

Powerful, versatile and scalable
Symphony Plus is the latest generation of ABB’s total plant automation platform for the power and water industries. This powerful, versatile and scalable platform is designed to maximize plant efficiency and reliability through automation, integration and optimization of the entire plant.

Symphony Plus enables plants and personnel to perform at maximum efficiency. It balances performance objectives like asset availability, operational reliability and production efficiency with business goals like asset life extension, carbon reduction and regulatory compliance. In so doing, it provides plant owners with an essential tool for achieving sustainable profitable growth.

There are more than 6,000 Symphony installations in operation all over the world, more than 4,000 of which are in power and water applications.
