The 28 September 2003 blackout in Italy raised doubts about the ability of distance relays in distinguishing voltage collapse and remote short-circuits. The combined presence of reduced voltages and high power flows may trigger distance relays, with the consequent tripping of healthy lines, reducing the system survivability. The paper addresses an analysis of the behavior of distance protections during...
Operator training is a relevant aspect of power system operation. In control centers, operators manage the power system through a man machine interface that is a source of further complexity for this critical infrastructure. This paper presents an approach for improving the features of power system Operator Training Simulator (OTS). The OTS program is aimed at training control center operators through...
Modern education in the area of power systems cannot be based only on theoretical knowledge. The main problem of education in this areas is due to the continuous and fast development of technology. The curricula must adapt themselves to technological development and, consequently, principles of laboratory education have to follow this trend as well. In this paper, the approach of a ldquomulti-functionalrdquo...
The monitoring of dynamic performances by means of WAMS allows keeping track of oscillation modes during the system operation and consequently detecting undesirable on comings of possible undamped oscillation behaviors of electric variables. In this paper, the problem of monitoring power system oscillation modes by means of a wavelet-based spectral analysis is addressed. A monitoring architecture,...
Real-time monitoring of power system dynamics can help in identifying poorly damped modes of oscillation and possible threats to the security of the system. System monitoring can avoid or mitigate the effects of black-outs if equipped with a good man-machine interface. In this paper, a monitoring architecture based on wavelet spectral analysis and WAMS is proposed. The wavelet analysis of real-time...
