Detection of Single and Dual Incipient Process Faults Using an Improved Artificial Neural Network
Authors
Abstract:
Changes in the physicochemical conditions of process unit, even under control, may lead to what are generically referred to as faults. The cognition of causes is very important, because the system can be diagnosed and fault tolerated. In this article, we discuss and propose an artificial neural network that can detect the incipient and gradual faults either individually or mutually. The main feature of the proposed network is including the fault patterns in the input space. The scheme is examined through a sample unit with five probable occurring faults. The simulation results indicate that the proposed algorithm can detect both single and two simultaneous faults properly.

This paper presents an innovative wormhole detection scheme an using artificial neural network for wireless sensor networks (WSNs). Most detection schemes described in the literature are designed for uniformly distributed sensors in a network, using statistical and topological information and special hardware. However, these schemes may perform poorly in non-uniformly distributed networks. Acco...
full textDetection of High Impedance Faults Using Artificial Neural Networks
High impedance faults (HIF) on electric power distribution feeders are of a great concern to electric power utilities. These faults often occur when a bare conductor breaks and falls to ground through a high impedance current path [1]. Some HIFs draw sufficient current to be cleared by overcurrent protection, however, many HIFs draw only small amount of current, which makes them difficult to de...
