Nowadays, the presence of nonlinear devices cannot be neglected either for their growing numbers or for their effect on the distribution network. In particular, these devices will produce relevant harmonics, which can cause problems such as increase of losses, over-heating in the power transformer malfunction of the circuit switch and, generally, an untimely aging process of connected devices. As...
In many power system applications it is required to assess the type and frequency of occurrence of power quality (PQ) events. Voltage waveform is one of the most regulated PQ — related issue. Although PQ is dealing essentially with steady-state energy transfer, the emerging power networks require faster control algorithms and therefore it is important to discriminate between steady-state, quasi-steady...
