MODELING RELAYS FOR POWER SYSTEM
PROTECTION STUDIES

by
SANDRO GIANNY AQUILES PEREZ



ABSTRACT
Numerical relays are the result of the application of microprocessor technology in relay
industry. Numerical relays have the ability to communicate with its peers, are
economical and are easy to operate, adjust and repair. Modeling of digital and
numerical relays is important to adjust and settle protection equipment in electrical
facilities and to train protection personnel. Designing of numeri ....etc

A dense gas is defined as any gas whose density is greater than the density of the ambient air through which it is being dispersed. This result can be due to a gas with a molecular weight greater than that of air or a gas with a low temperature due to auto-refrigeration during release, or other processes. The importance of dense gas dispersion has been recognized for some time. Early field experiments (Van Ulden, 1974; Puttock et al., 1982; Koopman et al., 1984) have confirmed that the mechanisms of dense gas dispersion differ markedly from neu ....etc

Abstract

Comparative studies on DWT-OFDM and FFTOFDM systems are presented. The model for DWT-OFDM includes zero-padding and vector transpose for transmitting the OFDM signal. MATLAB simulation commands are also described. The discrete wavelet transform-OFDM (DWT-OFDM) has to satisfy the orthonormal bases and the perfect reconstruction properties to be considered as wavelet transform. Different wavelet families have been used and compared with the conventional ....etc

ABSTRACT
The design, fabrication and testing of a novel neurochip structure for extracellular stimulation and recording of cultured neural networks are presented. The neurochip has 16 neuron wells, spaced 100 µm apart, in a 4 x 4 array, which are fabricated on a 9 mm by 3 mm silicon membrane, 20-µm-thick. The fabrication of the chips involves photolithography and micromachining on both sides of the membrane, which is located at the bottom of a 500-µm-deep cavity. Experimentally, the biocompatibility h ....etc

Photocatalysis is an advanced oxidation process and receiving widespread attention in recent times for completely mineralizing organic contaminants in water and air. As a first part of our study, the parameters (dissolved oxygen, catalyst concentration, and light intensity) influencing intrinsic kinetics of phenol degradation is investigated using immersion-well batch reactor with 6 and 125 W UV-A lamps. At high light intensity, dissolved oxygen concentration in the slurry decides the optimum catalyst loading. At low light intensity comparable ....etc

ABSTRACT
The stability of an interconnected power system is its ability to return to normal or stable operation after having been subjected to some form of disturbance. With interconnected systems continually growing in size and extending over vast geographical regions, it is becoming increasingly more difficult to maintain synchronism between various parts of the power system.
