Requirement Following the commissioning of the all electric ship’s power station, a phenomenon active power “pumping” (of several MW) between 2 diesel generators has been observed. This phenomenon is characterised by active power transfer in Read more…
Background The dynamic behaviour of mechanical torque sources driving alternators is fundamental in order ensure that the system frequency remains within the acceptable limits during load variations (connection/disconnection of loads, intermittence of renewable energy productions). Read more…
Background Overvoltages, overloads, power losses during a process, deterioration of distribution equipment or generators; these are all electrical incidents which sometimes occur in facilities or on electricity grids. Requirement Although they may sometimes have critical Read more…
Background 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 acceptance testing phase of the system parameters Read more…
Background A number of electrical phenomena corresponding to abrupt variations in the electrical variables of a system or a grid can be grouped together under the category of "electromagnetic transients". Here one can include phenomena Read more…
Background The design of an electrical power system or a multiphysical energy system (mixing various physical domains) goes through a certain number of steps and technical choices which are subject to hazards and risks, particularly Read more…
Requirement For the extension of the EDF Saint Raphael source substation, EDF wished to validate the sizing of the earthing system of the substation. Realization CAPSIM built a numerical model of the earthing system of Read more…
Background 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, for a company or on an industrial site, requires Read more…
Background The use of simulation software for analysis, design, understanding and control of electrical grids and systems is becoming increasingly common if not standardised. It often allows optimal choices to be made while limiting technical Read more…
Background The hybridisation of Diesel power stations or “fuels saving” is a strategy which consists in combining thermal power stations (Diesel, GTG, etc…) with renewable energy production sources (solar, wind) and eventually energy storage systems. Read more…
