  • 5000 kVA Multi-Tap Substation: A VanTran Signature Product!

    A VanTran signature product, the last week in September, we had a 5000 kVA multi-tap substation transformer leaving our facility. Earlier this summer, when power lines were accidentally cut on the coast of North Carolina, one of our loyal rental power customers supplied a VanTran Multi-Tap Substation they had in their rental fleet to help assist in getting power back up and running. Because the ...

  • The Future Promise of Vehicle-to-Grid (V2G) Integration: A Sociotechnical Review and Research Agenda

    Abstract Vehicle-grid integration (VGI) describes various approaches to link the electric power system and the transportation system in ways that may benefit both. VGI includes systems that treat plug-in electric vehicles (PEVs) as controllable load with a unidirectional flow of electricity, such as “smart” or “controlled” charging or time-of-use (TOU) pricing. ...

  • How Do Relays Function in Industrial Power Distribution Systems?

    How Do Relays Function in Industrial Power Distribution Systems? Power distribution systems that manage large currents come with components that protect the system from abnormal conditions, which can damage the unit. One of these components is a relay, which is used to isolate, limit or control electrical loads. Relays, or simple switches that are ...

  • Lighting Considerations for Indoor and Outdoor Sets

    Movie sets have meticulous lighting requirements. Optimal lighting conditions can enhance filming by contributing to the mood of the scene and illuminating dark spots in the shot. Bright lighting systems may also help promote safety for crew members setting up electrical wirings and installing fixtures on the set. Read on to learn about unique lighting considerations for indoor and outdoor sets. ...

  • Understanding Static Frequency Converter

    Static frequency converter means that's no rotary parts inside it - also called solid state - the definition is relative to rotary frequency converter which is using an electric motor to output adjustable frequency. Static frequency converter is changing fixed grid power through AC to DC to AC by inner electronic parts and components, the multifunctional inverter converts the mains (50 Hertz or ...

  • How to measure the direction of current harmonics?

    If the generation side of the point-of-common-coupling (PCC) is essentially an islanded setup consisting of a few specific generators, then the amount of harmonics resulting from the generation "source" can be readily identified in a mathematical fashion from the relative impedance on the generation side of the PCC compared to the combined impedance on the load side of the PCC. (The source of ...

  • Context–independent centrality measures underestimate the vulnerability of power grids

    Power grids vulnerability is a key issue in society. A component failure may trigger cascades of failures across the grid and lead to a large blackout. Within complex network analysis, structural vulnerabilities of power grids have been studied mostly using purely topological approaches, which assumes that flow of power is dictated by shortest paths. However, this fails to capture the real flow ...

  • Cascade failures and distributed generation in power grids

    Power grids are nowadays experiencing a transformation due to the introduction of distributed generation based on renewable sources. At difference with classical distributed generation, where local power sources mitigate anomalous user consumption peaks, renewable sources introduce in the grid intrinsically erratic power inputs. By introducing a simple schematic (but realistic) model for power ...

  • Knowing power grids and understanding complexity science

    Complex networks theory has been well established as a useful framework for studying and analysing structure, dynamics and evolution of many complex systems. Infrastructural and man–made systems like power grids, gas and water networks and the internet, have been also included in this network framework, albeit sometimes ignoring the huge historical body of knowledge surrounding them. Although ...

  • Correlating empirical data and extended topological measures in power grid networks

    Power grids are considered complex networks. Their structure and dynamics have been thoroughly studied and many topological measures have been used to classify them, evaluate their behaviour or model their response to malfunctions. Results have been theoretical and correlations between real dynamical behaviour (i.e., major events) and structural measures have not yet been found. New electrically ...

  • Neutronic calculation and power maps investigation of PWR critical lattice experiments using WIMSD-5B and CITVAP v3.1 codes

    The calculation of integral parameters and power distribution is a very important task for fuel assembly design and whole core safety analysis. In this work, we used Monte Carlo (MCNP5) and deterministic lattice cell code WIMSD-5B with the diffusion code CITVAP v3.1 to assess the accuracy of neutronic calculations of three PWR lattice benchmark problems defined by the ANS Ad Hoc Committee on ...

  • Integrated flexible parylene–based inductor with magnetic core for wireless power transmission system

    In this paper, flexible parylene–based MEMS inductors were designed, fabricated and analysed. A magnetic core was added in the centre of spiral coil in order to further enhance the performance of the inductor. FeNi alloy was chosen as the magnetic material due to its relatively high permeability. Parylene was used as substrate and insulation material due to its good bio–compatibility and ...

  • Avoiding the Power Grid with Renewable Energy

    For approximately one hundred years, thriving countries have been dependent on only one form of distributing power; electricity sent over large transmission grids from plants generating electricity, to customers in businesses, homes, and factories.  Generators extract energy from rooftop solar panels, garbage, and sewage, which replace or assist coal, nuclear, and natural gas plants. A ...
