The limitation of transmission lines thermal capacity plays a crucial role in the safety and reliability power systems. Dynamic line rating approaches aim to estimate line’s temperature assess its compliance with limitations above. Existing physics-based standards based on environment conditions measured by several sensors. This manuscript shows that estimation accuracy can be improved adopting...

Currently the operators of electrical distribution networks face a number of challenges, such as load growth, the proliferation of distributed generation and ageing infrastructure. This is drawing attention to techniques which will allow more efficient asset utilisation and facilitate network dynamic management. Power system component real-time ratings are a cost effective solution for increasi...

A thermal bridge is a part of the building envelope where the otherwise uniform thermal resistance is significantly changed by: • Full or partial penetration of the building envelope by materials with a different thermal conductivity and/or • A change in thickness of the structure and/or • A difference between internal and external areas, such as occur at wall-floor-ceiling junctions. INTRODUCT...

Cascading failure causes a major risk to society currently. And dynamic thermal rating (DTR) technique is cost-effective approach mitigate the by exploiting potential transmission capability. From perspectives of service life and Braess paradox, it important challenging jointly optimize DTR placement its operation schedule for changing system state, which two-stage combinatorial problem with on...

While ASTM E119-07a is commonly employed to establish a fire rating for a fire resistive material (FRM)/steel assembly, the test method provides little quantitative information on either the thermophysical or adhesion properties of the FRM, beyond indicating that they are sufficient to achieve the measured rating. As part of the Building and Fire Research Laboratory (BFRL) Structural Performanc...

primary mgcl2.3.3etoh adduct (pct1) was prepared by melt quenching method and then submitted into a programmed thermal dealcoholation project using a fluidized bed reactor. during thermal dealcoholation program, different mgcl2.netoh support samples with n= 3.0, 2.7, 2.4, and 2.1 were selected and named as pct2 to pct5, respectively. structural analysis of the support samples showed a significa...

Dynamic rating is an approach which implies to operate electrical network closer its thermal limits. This may be very beneficial for wave farms, as they are expected present a highly fluctuating current profile while benefiting from the large inertia of soil where their export cable will buried. However, implementation this still in infancy offshore wind it that first under form small-scale tes...
