Transients in Electric Power Systems

Course overview No.: 35616 & 35618

German title: Ausgleichsvorgänge in Elektroenergiesystemen

The students learn mathematical models and solution methods tailored to the electrical three-phase system. Lecture is held on Mondays from 01:00 pm to 02:30 pm. The exercises are held on Mondays from 02:45 pm to 03:30 pm.


After successful completion of the module, students are able to work with appropriate computer programs and are able to:

  • interpret transient processes in networks and describe the multi-time scale character of electrical energy systems
  • apply modal components in stationary and rotating reference frame and space vectors for the calculation of transients
  • describe electrical equipment mathematically for simulations in the time domain
  • calculate transient processes after switching operations and faults
  • formulate the state-space representation of electric power systems
  • use the extended nodal approach and construct an differential-algebraic equation system for electric power systems
  • perform a numerical integration of (algebro-)differential equation systems
  • use the difference conductance method to calculate transients
  • explain the origin of overvoltages and estimate the magnitude of overvoltages
