Response of Marine‐Terminating Glaciers to Forcing: Time Scales, Sensitivities, Instabilities, and Stochastic Dynamics [PDF]

, 2018
Recent observations indicate that many marine‐terminating glaciers in Greenland and Antarctica are currently retreating and thinning, potentially due to long‐term trends in climate forcing.

Simulation and analysis of single-phase grounding fault in small current grounding system

Journal of Physics: Conference Series, 2019
Abstract The characteristics and distribution of single-phase grounding faults in small current grounding system are not easy to capture, and it is not easy to collect and cover all possible situations in operation site. This paper builds a fault simulation model of distribution network based on PSCAD.

Potential climatic transitions with profound impact on Europe [PDF]

, 2011
We discuss potential transitions of six climatic subsystems with large-scale impact on Europe, sometimes denoted as tipping elements. These are the ice sheets on Greenland and West Antarctica, the Atlantic thermohaline circulation, Arctic sea ice, Alpine

Research of Single-phase Grounding Fault Simulation for Small Current Grounding System

DEStech Transactions on Environment, Energy and Earth Sciences, 2017
Our country generally uses small current grounding system (the neutral point no direct grounding system). Due to the fault current is too small to identify. So the distribution network operators have been plagued by this kind of fault line selection accuracy. This research establishes simulink model to analyze the fault of single-phase grounding system

Grounding System Adequacy of HV/MV Substations in Areas With Reduced Accessibility [PDF]

, 2015
The adequacy of grounding systems has to be verified periodically in the operational time. With urban development and buildings growth adjacent to power systems as HV/MV substations, it is very rare to have area around with sufficient accessibility for ...
