Selectivity study for the Severstal site

As part of the construction of the Severstal industrial site in Russia, Capsim carried out a study of the protection plan of all the HV and LV electrical grids. [...]

Reliability of the network and selectivity study

The site studied was a very large facility undergoing reconversion that would result in it accommodating new consumption units and new generators (biomass plant) using the existing electrical grid. In this configuration, the operator, via a suitable structure, must ensure the supply of utilities (steam, electricity, etc.) for all of the industrial units present on the site. The realization of this service relies directly on the concepts of availability and reliability of the grids and the generators.
In this context, the project involved producing:

• An audit of the electrical grid consisting of identification of the strong and weak points of the HVA distribution network, in order to make the HVA grid reliable,
• A complete review of the protection plan in light of the results from the dynamic study and the replacement of analogue protection relays by a new generation digital relays.

Study for updating the protection plan of a 10 kV port distribution grid

The distribution grid of the Arsenal de Toulon is one of the largest private grids in France with more than 150 transformer stations.
Because of the obsolescence of certain protection devices and the limitations of the current protection plan, the management sought assistance to successfully complete the work with a view to updating the protection plan for the 10 kV - 50 Hz high voltage grid supplying its site. Moreover, it wished to improve the reactive energy compensation of the network in order to reduce its energy bill. [...]
