BASIC INSTRUMENTATION MEASURING DEVICES AND BASIC PID CONTROL


INTRODUCTION
Instrumentation is the art of measuring the value of some plant parameter,
pressure, flow, level or temperature to name a few and supplying a signal
that is proportional to the measured parameter. The output signals are
standard signal and can then be processed by other equipment to provide
indication, alarms or automatic control. There are a number of standard
signals; however, t ....etc

ARTIFICIAL INTELLIGENCE APPLICATION TO POWER SYSTEM PROTECTION


INTRODUCTION:

The microprocessor technology brings unquestionable improvements of the protection relays- criteria signals are estimated in a shorter time; input signals are filtered-out more precisely; it is easy to apply sophisticated corrections; the hardware is standardized and may communicate with other protection and control systems; relays are capable of self-monitoring. All t ....etc

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
