Modelling a power plant's main electrical components makes the simulation of electrical transients possible in order to identify the cause of an incident.

It also facilitates decision-making during the study of alternatives for rehabilitation.

Electrical transient simulation is a valuable tool. The modelling of a hydroelectric power plant's main electrical components offers many possibilities:

  • reproducing various types of electrical faults in order to identify the cause of an incident that occurred during operation
  • evaluating a machine's capacity to withstand electrical transients, such as FRT (Fault Ride Through), as specified in the Transmission Code
  • validating the feasibility of alternatives as part of a renovation study
  • verifying characteristics indicated by suppliers during a tender procedure.

Méthodologie

  • define the study's scope and objectives
  • establish various simulation scenarios
  • gather the parameters and characteristics of the components to be modelled
  • model the layout in the SIMSEN software package
  • validate the model by comparing measurements, if available
  • simulate predefined scenarios and analysing results
  • prepare a study report
