with increasing the presence of microgrids (mgs) in the power systems, investigating the mg stability during transient faults is necessary. this study investigates the transient stability analysis of a mg supplied by multiple inverter interfaced distributed generations (iidgs) during fault. the transient stability of a mg is highly depends on the iidgs control strategy. a mg, simulated on matla...

The Wenchuan earthquake of 12 May 2008 is the most destructive earthquake in China in the past 30 years in terms of property damage and human losses. In order to understand the earthquake process and the geo-morphological factors affecting the seismic hazard, we simulated the strong ground motion caused by the earthquake, incorporating three-dimensional (3D) earth structure, finite-fault ruptur...

Fault simulation of a test set in an order different from the order of generation (e.g., reverse or random order fault simulation) is used as a fast and effective method to drop unnecessary tests from a test set in order to reduce its size. Recently in [1], we proposed an improvement to this type of fault simulation process that makes it even more effective in reducing the test set size. The pr...

Fault diagnosis of downhole traction robot has characteristics special mechanical structure, complicated working condition and lack research data. In this paper, a method fault analysis tractor hydraulic system based on model is presented. The failure mode mechanism key components in telescopic are analyzed. proposed the mathematical component. Based AMESim, established, single multi-fault simu...

PROOFS (Parallel RestOrative Orderindependent Fault Simulator) is a hybrid of concurrent, differential, and parallel fault simulation algorithms. It retains fault dropping advantage of concurrent method, word level parallelism of parallel method and low memory requirement of differential, while minimizing their individual disadvantages. Parallel simulation of faults reduces simulation time of P...

Cosmogenic chlorine-36 reveals dates of the multiple prehistoric earthquakes that have produced a scarp on the Hebgen Lake fault. Apparent chlorine-36 ages are stratigraphically correct, follow a predicted theoretical pattern, and produce geologically reasonable model ages of 24, 20, 7.0, 2.6, 1.7, and 0.4 thousand years ago. This result demonstrates the feasibility of using cosmogenic chlorine...

The recent 2011 Mw 9.0 Tohoku, Japan, and the 2004 Mw 9.15 Sumatra–Andaman superquakes have humbled many in earthquake research. Neither region was thought capable of earthquakes exceeding Mw ∼ 8:4. Appealing proposed relationships to predict the size of earthquakes in subduction zones, such as that between earthquake magnitude and parameters such as lower plate age and convergence rate (Ruff a...

(Draft Paper) This paper discusses an industrial application of a neural network based automatic scheme for fault detection and diagnosis. Faults in a lime kiln are isolated and detected, using two multilayer feedforward networks. One is used to model the industrial process according to its nonlinear structure. The fault detection method is based on the output prediction error between the real ...

In this paper, performance evaluation of different schemes for location of fault in series compensated transmission lines are presented. A fault location algorithm using two end measurements and another fault location algorithm using one end measurements for transmission lines with series compensator at midpoint are simulated and results are obtained. Both the schemes are compared on the basis ...
