  • Loss calculations and loss optimization,

  • Transient calculations (e.g., inrush currents, switching overvoltages),

  • Stability investigations / dynamic calculations,

  • Power quality investigations,

  • neutral point treatment,

  • grounding,

  • reliability calculations,

  • Assessment of grid connection requests / connection planning,

  • Simulation of critical network situations,

  • Black out prevention & network reconstruction investigations,

  • Fault analysis and clearing,

  • Investigations on reactive power balance and load management.

 

What services do we offer for optimization & development?
  • Technical and economic optimization of individual equipment, plants, or entire networks,

  • design of operating equipment regarding technical and, if necessary, economic target functions (e.g., transformer and cable dimensioning),

  • thermal simulation of cables for continuous and alternating loads based on project-specific electrical parameters and ground properties

  • Reliability calculation,

  • Target network planning/network expansion planning considering demographic, economic and technological developments,

  • network connection point optimization

NETWORK OPTIMIZATION & NETWORK DEVELOPMENT

Network operators must regularly test whether their networks meet current and future requirements. This test has become increasingly important due to energy and mobility changes. In addition, existing design principles are only valid to a limited extent under the new boundary conditions.

Our survey methodology is innovative in many respects and is based on measurements, generator and consumer time series, operational experience, and demographic, normative and political developments.

RECONSTRUCTION PLANNING OF GRID INFRASTRUCTURES:

The transition to a sustainable energy supply with a decentralized generation structure and increased energy exchange with neighboring countries pose new challenges for the existing grid infrastructure. Therefore, the security of supply of transport and distribution networks must be ensured by their reconstruction.

We are always at your side, from the planning and organization to the implementation of your projects. Our experienced engineers support you in your conversion planning and combine all specialist departments such as network planning and system management, construction of substations and lines, and long-distance transmission technology and approval service.

What services do we offer for network infrastructure planning?
  • Development of reconstruction concepts as well as consideration of variants,
  • Creation and visualization of chronological sequence plans,
  • Coordination and communication between departments,
  • identification of dependencies, interface coordination,
  • Review and quality assurance of technical concepts,
  • Detailed circuit planning for the entire conversion process,
  • Sensitivity analysis with parallel conversion projects,
  • network planning evaluation of conversion steps regarding their technical feasibility,
  • Common-mode consideration of network states,
  • Documentation of partial planning, meetings, and decision preparation.
