In this paper principles of extended Kalman filtering theory is developed and applied to simulated on-line electric power systems state estimation in order to trace the operating condition changes through the redundant and noisy measurements. Test results on IEEE 14 - bus test system are included. Three case systems are tried; through the comparing of their results, it is concluded that the pro...

This paper deals with cost – effective optimum design of parallel redundant system. The components in the redundant system are assumed to be identical and failure time follows exponential distribution. This paper suggests optimal spares (S*) required for redundant configuration in parallel redundant system. The results are presented for common cause failures with fault coverage.
