Services overview
Power grid studies
Dynamic stability study
An electricity grid may sometimes be subject to abrupt changes in its operating conditions, either in normal operation or due to an incident….
Power flow and voltage plan study
Existing electricity grids are sometimes subject to modifications: restructuring of the grid, equipment modifications, load modifications…
Short-circuit current calculation
At any point on an electricity grid, there is a risk that a short circuit will appear. Such short-circuits immediately cause circulation of large …
Selectivity study
Within an industrial electricity grid, the protection of goods and people requires a protection plan to be put in place…
Harmonic analysis
The presence of increasingly large power-electronics equipment (inverters, converters, motors with variable-frequency drive supplies, etc.) …
Sizing an electricity distribution grid
As part of the design and development of distribution grids, whether they be public (e.g. town grids), or private (e.g. industrial sites)…
Study of Earthing system
Study of electromagnetic transients
A number of electrical phenomena corresponding to abrupt variations in the electrical variables of a system or a grid can be grouped together…
Simulation engineering
Development of calculation tools
The risks associated with a project can be reduced by anticipation. For this purpose, numerical simulation is often a very useful alternative …
Training
The use of simulation software for analysis, design, understanding and control of electricity grids and systems is becoming increasingly …
Energy systems
Functional analysis
Good performance of a project begins with a clear definition of the requirements. Installation of a back-up generator, new equipment or a new simulation tool …
Reliability study
The design of a system must ensure that it is capable of carrying out the functions for which it has been created. These conditions often require strict …
Incident consultancy
Overvoltage, overload, loss of power to a process, deterioration of distribution equipment or generators; these are all electrical incidents which sometimes …
Assistance with the design of systems
The design of an electrical power system or a multiphysics energy system (mixing various physical domains) goes through a certain number of steps and technical…
