Electrical grid engineering, protection relay selectivity studies

Modeling of electrical grids and electro-technical study services

Engineering and high-voltage expertise

Based on our high-voltage expertise, we conduct preliminary surveys and draw up detailled bills of specification for upgrading your systems and rendering them more reliable.

Using powerful calculation tools to conceptualize electrical grids, we are able to conduct various electrotechnical studies:

Electrotechnical studies:

  • Short-circuit studies in compliance with CEI 60909
  • Protection relay selectivity studies
  • Study of power flow and voltage plan
  • Dynamic stability studies: short circuit, load impact, source changeover
  • Charting [U;Q] and RTE protectability studies for connection of electricity generators
  • Formulation of regulation strategies in P and Q for electricity storage systems
  • Harmonic pollution studies
