T. Saengsuwan et al., EXPERT-SYSTEM APPLIED TO THE BACKUP PROTECTION OF A TRANSMISSION NETWORK, Engineering intelligent systems for electrical engineering and communications, 4(1), 1996, pp. 43-48
The paper will describe a new type of protection, designed to provide
back-up protection for a region of a transmission network. The protect
ion uses an expert system, based on the shell GoldWorks III. This dete
rmines the optimum response to the fault, based on the knowledge of th
e network configuration and the operating response of the main protect
ion. The back-up protection clears the fault, if one of the main prote
ction relays and its associated circuit breaker failed to operate. The
paper will include results showing the response of the back-up protec
tion when rested using a power system simulator.
