Generation, Transmission & Distribution, Consumers & Industrial Applications, Manufacturers, Infrastructur, Research & Development, Authorities & Legislations.

Productiontop

Large and medium sized synchronous generators are still the main source for electric power generation. These generators are continuously upgraded, replaced and modified to increase the production and to improve the efficiency. Different kinds of small generators, embedded in the distribution systems, are emerging rapidly in most power systems today. Large wind power farms, of the same size as large traditional generators, are now connected directly to bulk power systems. These trends in modern power production systems require a broad engineering overview as well as detailed knowledge about the components and phenomena involved, for proper design and operation.

Gothia Power performs studies necessary to plan, design and operate generators e.g:

    • Basic design features
    • Real and reactive power control
    • Machine protection coordination
    • Technical and economical comparisons
    • Steady state behaviour as a part of large power grid
      • Synchronization
      • Pullout power
      • Optimal operating etc.
    • Transient machine behaviour
    • Dynamic studies in multi-machine systems

Measurementtop

Measurements are the main source of knowledge extensions in all technical areas. Measurements, in combination with analysis, modelling and simulations, have been the basic concept within research, development, planning and operation of electric power systems, since the beginning of the electricity era. Together with partners, specialised in field measurements, Gothia Power performs measurements and analysis to:

    • Evaluate Power Quality Issues
    • Verify Electromagnetic Compatibility
    • Study Electric Transients in Power Systems
    • Test and Verify Dynamic Performance of Governors and Voltage Controllers
    • Study Phasors based on GPS-synchronization

Transmission & Distributiontop

Power system planning and design requires great knowledge and insight of existing systems to provide a firm base for accurate assessment of projects for future network development. Technical aspects influencing network protection, reliability, future loads, etc. need to be considered. However, it is essential that any project under consideration must be examined and evaluated from its technical conditions, as well as, from its economical potential, to ensure that every project decided is sound and cost effective.

Gothia Power performs studies necessary to plan, design and operate transmission and distribution networks, including areas as:

    • Power flow and losses
    • Faultcurrent calculations
    • System protection design and coordination
    • Load shedding
    • Real and reactive power compensation and control
    • System control and stability
    • System earthing
    • Network configuration and voltage performance
    • Modelling of network components
    • Economic principles of network planning
    • Laws, Regulations and Standards
    • Concession investigations
    • Commission of inquiry on faults, blackouts

Researchtop
