Electromagnetic Transients in future Power Systems

The future power system is going to be highly complex: integration of renewables, smart grids, voltage upgrades, more usage of long cables. Its implementation will require extensive computer simulations during its planning an engineering phases.  Existing simulation tools have limited accuracy for representing some critical components such as transformers and cables. The project will produce models that are sufficiently accurate and compatible with available circuit simulators, and make use of the models in system simulation studies in order to pinpoint bad configurations. The models will be available for other users. 

The main tasks of the project are:

  1. Review of future trends in land base and offshore power systems
  2. Improve component modeling
      a) Transformer modeling
      b) Cable modeling
      c) Circuit breaker modeling
      d) Instrument transformer modeling
  3. Perform demo simulations to investigate:
    - system overvoltages caused by high-frequency interaction between cables and transformers (switching events and faults)
    - winding overvoltages caused by restrikes in vacuum breaker
    - phenomena related to energization and faults in power systems with long cables
