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

Power System Protection




Definition


Overcurrent Coordination
A systematic study of current responsive devices in an electrical power system.

Design

Open only PD upstream of the fault or overload
Provide satisfactory protection for overloads
Interrupt SC as rapidly (instantaneously) as possible
Comply with all applicable standards and codes
Plot the Time Current Characteristics of different PDs


Protection vs. Coordination

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
