Autonomic Computing Application in Power System Distributions

Maintaining the reliability and stability is an important subject in power system distributions research area. Recently many IT applications have been implemented successfully in power system; such as numerical relays, digital distribution management systems (DMS), and energy management systems (EMS). This paper presents an implementation of an integrated external monitoring system to identify and recover the failure in numerical over current relay using neural network. This approach will then be used as a monitoring unit in self-healing which is one of the main characteristics of autonomic computing. Feed forward neural network is implemented to measure and predict the availability of substation numerical protection in order to enhance their availability.
