Hydraulic transients in hydropower plant : Impact on power system dynamic stability [PDF]
, 2014 Futaleufú hydropower plant has 4 Francis turbines rated 118 MW and it is connected to the power system by 2x330 kV lines. Studies carried out in the past did not predict the instable operation of Futaleufú after a 330 kV line fault, when some Futaleufú ...

Electromagnetic Transients on Power Plant Connection Caused by Lightning Event
, 2021 Lightning events can seriously damage the power systems and they represent one of the most dangerous causes of faults in the transmission lines. Usually, when one want to analyze such effects it is necessary to rely on approximate models or to simplify ...

Power-line communication channel model for interconnected networks. Part I : two-conductor system
, 2009 This paper presents a generalized transmission-line approach to determine the transfer function of a power-line network of a two-conductor system (two parallel conductors) with distributed branches. The channel frequency responses are derived considering
