Based on the transient circuit model of series compensated line, a new method for identifying the fault location relative to series capacitor (SC) is proposed. Comparing the transient model of series compensated line when fault occurs before the SC and the one when fault occurs after the SC, it is found that the only difference is the value of a model-parameter: it respectively equals 0 and a large...
This paper presents a fault location procedure for distribution networks, based on the use of wavelet packet analysis of the voltage transients associated with the fault-originated traveling waves. The proposed method just needs the measured voltage transients recorded at the observation point without the need of multi-recording nodes and relevant synchronization. Fault-originated traveling waves...
Stream processing is widely used by today's applications such as financial data analysis and disaster response. In distributed stream processing systems, machine fail-stop events are handled by either active standby or passive standby. However, existing high availability (HA) schemes have not sufficiently addressed the situation when a machine becomes temporarily unavailable due to data rate spikes,...
Procurement and the optimized utilization of Petascale supercomputers and centers is a renewed national priority. Sustained performance and availability of such large centers is a key technical challenge significantly impacting their usability. Storage systems are known to be the primary fault source leading to data unavailability and job resubmissions. This results in reduced center performance,...
MCT connected in circuit alters internal electrical parameters of generator. This means the generator mathematical model isn't identical with the generator in experiment. This makes the generator modeling more complicated. Rogowski coil doesn't contact with measured circuit. It won't change parameters of generator. Based on simulation and experiment, the paper introduces a current sensor composed...
