Osaamistavoitteet

Student having taken the course should understand the principles of how an electrical power system is planned and operated. They are expected to model and analyse the steady-state and dynamic performance of simple power systems using: power flows; short-circuit fault current calculations and the various forms of power system stability assessments. Student should be able to carry out simulation studies of practical power systems operating under steady-state and dynamic conditions using commercial power system analysis software; to check the sanity of the simulation results by resorting to basic theory; to assess the operation of the actual power system under study and to produce a well laid-out simulations report.
