Signal and power integrity are crucial for ensuring high performance in high speed digital systems. As the operating frequency of digital systems increases, the power and ground bounce created by simultaneous switching noise (SSN) has become a limiting factor for the performance of these devices. SSN is caused by parasitic inductance that exists in the power delivery network (PDN), and voltage fluctuations...
Black start studies are typically performed as part of system restoration plan when an isolated section of the grid completely shuts down and there are no neighboring systems to assist with the energization. In these cases, pre-selected units with the ability to start themselves with a well established energization plan are used to restart the system. As a case study, a power system comprising of...
This experiment investigates on the possibility of inducting energy directly from transmission line for inspection robot on high-voltage transmission line. In this experiment, the first aspect analyzed was the influence of amount of current flowing through high-voltage line on the energy induced. The second aspect analyzed in the experiment was the influence of resistance in the secondary side on...
This paper puts forth a framework for estimating the transmission line parameters (including series resistance and reactance and shunt susceptance), line temperature and sag employing synchronized phasors obtained by Phasor Measurement Units (PMU) in real time. The estimated temperature and sag can be utilized for dynamic thermal rating for increased power transfer. The proposed algorithms harness...
When a fault occurs on a transmission line, fault-generated high-frequency signals contains a lot of information about fault. This paper proposes a fault location scheme for transmission lines based on spectrum characteristic of high-frequency components, the difference of adjacent two natural frequencies in one ends of transmission line is used to compute fault distance. This method need not identify...
This paper presents the measured impedance by a distance relay in the presence of thyristor controlled series compensator (TCSC), one of the series connected FACTS devices, on a transmission line, considering its metal oxide varistor (MOV) operation, in the case of inter, phase to phase and three phase, faults. The measured impedance at the relaying point is affected by the power system structural...
