This paper proposes an effective model for evaluating vertical signal propagation delay in through silicon via (TSV) based three-dimensional integrated circuits (3-D ICs). The capacitance model for on-chip interconnects is also proposed. All parasitic parameter values for an entire structure can be calculated by the closed-form equations. The delay model is constructed with the first- or second-order...
This paper presents a method for the tuning of a power system stabilizer (PSS) for damping inter-area low-frequency oscillations based on wide area phasor measurements and robust controller design with the linear matrix inequality (LMI) approach. The dynamics of a power system is identified as an approximate model based on voltage phasors obtained by the wide area measurement system (WAMS). Then,...
This paper presents a brief summary of issues on industrial customer's electrical power systems and an approach to analyze the transient behavior of a system with the group of self-generators, substations and many induction motors. Power oscillations and voltage recovery performance after some contingencies are recognized as typical issues on customer's systems. The strong nonlinearity caused by the...
Industrial electric power systems such as factories (steel, petro chemistry and paper pulp) which have customer's power generating plants have very complicated system structures. Most of loads in industrial electric power systems consist of induction motors and synchronous motors. In addition, these systems are usually interconnected with utilities. Therefore, voltage instability phenomena caused...
