The consequence of station blackout in a nuclear power plant
The main purpose of the nuclear power plant is to generate electricity and to supply it to the grid and its auxiliaries systems. Since nuclear safety overrides the production of electricity and therefore nuclear power plants are designed to protect the public and the environment from the radiation …

Application of Ab-initio Quantum Chemistry Techniques to Hypersonic Flows for Plasma Blackout Alleviation
Plasma blackout in hypersonic flows produced by weakly-ionized air plasma sheaths is a phenomenon that attenuates or completely blocks communications with vehicles flying in a high-enthalpy flow environment. The ability to mitigate this issue can be useful from various re-entry vehicles to …

Experimental Design of Electrophilic Gas Injection System for Plasma Blackout Mitigation during Hypersonic Reentry
Radio communication blackout during hypersonic reentry has been a prolonged issue for all planetary missions. Though blackout mitigation techniques were investigated heavily in the 1960s and 1970s, the lack of fidelity in computational tools and integrated ground/flight testing with adequate …

Mitiiation of Blackout in Kigali Using a Microgrid with Advanced Energy Storage and Solar Photovoltaics
A blackout is defined as the loss of electric power for a given period in a particular area. With increasing dependence on reliable electric power, the social and economic ramifications of blackouts are dire, negatively impacting the productivity, safety, and security of communities. To reduce …

Multiple schedules: the effects of temporal factors on behaviour
… decreasing the duration of an intercomponent blackout. Six hens served in this experiment. Blackout durations examined were 1 s, 10 s, 30 s, 60 s, 120 s, 180 s and 297 s. At each blackout duration the reinforcement rates in component schedules were varied. Response rates on both components of …

Internal Representations and the Importance of Active Control in Dynamic Spatial Orientation
… briefly blacked out. In Experiments 1 and 2, the blackout was followed by a static image. Subjects in these experiments were required to indicate whether they were in the correct or incorrect orientation following the blackout. In Experiment 3, simulated locomotion continued for a period following …

The Capabilities and Limitations of Flywheel-based Energy Storage System Pertaining to Subways in the Event of a Power Outage
… the city that never sleeps, power outages or blackouts can be a shock, especially if you are on a train amid one. For example, during the infamous 2003 blackout, thousands of people were left stuck and stranded in parts of Northeastern United States. In particular, with no trains or buses in …

A novel safety analysis method for marine cyber-physical systems
… Failure rate for 12 DEP system alternatives blackout is also estimated. The derived results for the scrubber system and DEP system demonstrate that the developed Fault Tree is much richer than for the previous studies. Moreover, it is demonstrated that the increase of the DEP system …

Greenhouse climate model : an aid to estimate the influence of supplemental lighting on greenhouse climate
… June and July. Artificial lighting and movable blackout screen are therefore needed to have a year round production. Replacement lighting requires a high density of lighting devices which implicates a big heat gain due their losses. Understanding the influence of the artificial lighting on the …

Critical point study in the Sabah power grid for cascading failure blackouts
… than before. In April and May 2012, two blackout events took place successively in the power grid of Sabah, which led to the major blackout. Currently, faulty issues in the system can lead to the cascaded failure to the system grid. These issues also can affect the rotor angle of …

Do drinking consequences predict sexual revictimization in a college sample of binge-drinking women?
… were revictimized in the following 30 days. Blackout drinking at baseline predicted incapacitated sexual revictimization among women previously victimized as adolescents, after accounting for quantity of alcohol consumed. Other drinking consequences examined were not predictive of …

WAMS-based Intelligent Load Shedding Scheme for Preventing Cascading Blackouts
… minutes, they are ineffective during a rolling blackout. While traditional Under Frequency Load Shedding Schemes (UFLS) perform quick control actions to arrest frequency decline in an islanded network, they are not designed to prevent unplanned islanding. The proposed Intelligent Load Shedding …

Vehicle to grid (V2G) for reliable microgrid operation: Voltage/frequency regulation and real-time OPAL-RT digital simulation
… emergency situation that happens by a fault or blackout so the system will be disconnected from the grid, in a concept that a home (or residence) is equipped with a PV (Photovoltaic) system and Electric Vehicle (EV) with V2G/V2H (Vehicle to Grid or Vehicle to Home) capability. A Phase to ground …

Evaluation and Standardizing of Phasor Data Concentrators
… can be seen across large areas causing major blackouts. In order to isolate the fault, measurements taken at different times throughout the blackout need to be collected and analyzed. With each measurement device having its own time source, time alignment can be a quite tedious and lengthy …

Stochastic Dynamics of Cascading Failures in Electric-Cyber Infrastructures
… enables the prediction of the evolution of the blackout probability in time. Furthermore, the asymptotic analysis of the blackout probability as time tends to infinity enables the calculation of the probability mass function of the blackout size, which has been shown to have a heavy tail, e.g., …

Power systems modeling for multiple infrastructure damage and repair simulations
… system was also developed, along with a post-blackout restoration procedure. Using these, simulations of a post-blackout recovery were carried out to study the level of risk that communications outages may pose to the electrical network's recovery. These simulations revealed a correlation …
