This paper proposes a new scheme of induction motor parameter estimation using Genetic algorithm (GA) for condition monitoring. The flux linkage model and torque model of an induction motor is adapted to the estimation. The scheme is developed to obtain all the motor parameters: stator and rotor resistance, stator and rotor leaking reactance and magnetizing reactance, which paves the way to dia...

We have developed a mobile thin-client server named ”HTTP-FUSE-KNOPPIX-BOX” that incorporates mechanisms for increasing performance, distributing load, and providing fault tolerance to achieve a practical HTTP-FUSE-KNOPPIX-based thin-client environment for mobile systems and other environments with limited hardware resources such as CPU and memory. Software RAID raises file input/output perform...

Mobile ADHOC networks is a wireless network consists of number of nodes. The nodes consists of sending packets from source to destination via path connection. The path connection is of multipath routing and it is very unstable and go down at any time and making the connection on ADHOC network is difficult. If primary path fails to send the packet to destination then the secondary path is used t...

In distributed object systems, application level fault tolerance is often attained by appropriate object replication policies. These policies aim at increasing the exhibited service availability by masking potential faults that do not recur after recovery. Existing middleware support infrastructures allow customizing object replication properties. However, since fault tolerance has a significan...

In this paper, two-dimensional time-stepping finiteelement (TSFE) method is performed for modeling and analyzing of a salient pole synchronous generator with different degree of dynamic eccentricity (DE) fault. TSFE analysis is used to describe the influence of DE fault on the flux distribution within the generator and no-load voltage profiles at low and high field current is obtained for healt...

DC faults may cause severe disruptions in continuity of service to vital loads in a shipboard integrated power system, hence detection, isolation and protection against dc faults must be incorporated in both medium-voltage dc and low-voltage dc systems. A standard z-source breaker can identify and de-energize a faulty dc load on both buses quickly. However, until now, provisions for re-energizi...

Flux coupling in heteropolar magnetic bearings permits remaining active coils to assume actions of failed coils to produce force resultants identical to the un-failed actuator. This fault-tolerant control usually reduces load capacity because the redistribution of the magnetic flux which compensates for the failed coils leads to premature saturation in the stator or journal. A distribution matr...

In this paper, fault-tolerant feature of TOPAS parallel programming environment for distributed systems is presented. TOPAS automatically analyzes data dependence among tasks and synchronizes data, which reduces the time needed for parallel program developments. TOPAS also provides supports for scheduling, load balancing and fault tolerance. The main topics of this paper is to present the solut...

the use of renewable energy in power generation and sudden changes in load and fault in power transmission lines  may cause a voltage drop in the system and challenge the reliability of the system. one way to compensate the changing nature of renewable energies in the short term without the need to disconnect loads or turn on other plants, is the use of renewable energy storage. the use of ener...
