This paper reports on an investigation into the space charge formation and decay at different material interfaces. In particular, influence of interface between electrode polymer or dynamics has been studied. Planar samples were subjected to high DC electric stresses for extended periods time measurements taken using pulsed electroacoustic (PEA) technique. It found that types play a significant role in determining distribution insulation acts as potential barrier electrons while allowing...
A novel combustion system was applied to a 600 MWe Foster Wheeler (FW) down-fired pulverized-coal utility boiler solve high NOx emissions, without causing an obvious increase in the carbon content of fly ash. The unit included moving fuel-lean nozzles from arches front/rear walls and rearranging staged air as well introducing separated overfire (SOFA). Numerical simulations were carried out under original systems evaluate performance emissions furnace. simulated results found be good...
Abstract In this paper, we expolore Multi-Agent Reinforcement Learning (MARL) methods for unmanned aerial vehicle (UAV) cluster. Considering that the current UAV cluster is still in program control stage, fully autonomous and intelligent cooperative combat has not been realised. order to realise planning of according changing environment cooperate with each other complete goal, propose a new MARL framework. It adopts policy centralised training decentralised execution, uses Actor-Critic...
This position paper by the DEIS HVDC Cable Systems Technical Committee provides a review of existing diagnostic electrical and dielectric techniques for testing insulation polymeric extruded cable joints in present Part 1. Here, state art on system is covered with reference to types, design techniques. helps identify routine tests as first target onset new procedures, AC-PD measurements readily-available measurement from manufacturers' practices quality control accessories during VHF/UHF...
In crude oil production, scale deposition significantly reduces production output and elevates operational costs, posing a severe threat to safety. While chemical methods have been extensively explored for the scaling inhibition of inorganic salts, triggered by solid particle in complex oilfield water has largely overlooked. This study involves introduction particles into supersaturated CaCO3 solution, utilizing static conductivity techniques examine their influence on process...
This paper proposes a theoretical model for ship-bottom plate tearing when the ship runs grounding over cone-shaped rock. The non-linear finite element code LS_DYNA is used to simulate scenario, observe deformation modes and also verify proposed model. A simplified, kinematically admissible developed capture major energy dissipation patterns, which include friction, stretching, bending, fracture. Based on upper bound theorem, analytical expression of resistance due in moving direction...
With the rapid development of urban rail transit and underground space development, occurrence excavation near existing tunnels is becoming more common. This unloading will inevitably cause soil deformation outside pit tunnel buried therein. paper presents an investigation into entire process effects on adjacent subway structure under complex construction environments, including soft foundations intersections, based measured data construction. The horizontal vertical displacements deep soils...
High voltage direct current (HVDC) cables are one of the key components for HVDC power transmission system. higher level, larger capacity and reliability still desired industry as part a global strategy. One major concerns related to applications is presence space charge within dielectrics, which distorts electric field distribution contributes accelerated ageing consequent failure cable insulation. The byproducts generated from crosslinking process during manufacture XLPE insulation sources...
HVDC cables play a vital role in the power transmission system for renewable energy and global trade. Nowadays, crosslinked polyethylene (XLPE) extruded have been widely applied industry due to superior performance on thermo-mechanical properties dielectric properties. The low volume conductivity minimized space charge accumulation are two key requirements reliable high voltage direct current (HVDC) cable insulation. This paper reports impact of temperature electric field behavior DC XLPE...
When the amplitude of oscillation unsteady flow is large or there perturbation relative to mean background flow, traditional proper orthogonal decomposition/reduced order model (POD/ROM) based on linearized time frequency domain small disturbance solvers cannot capture main nonlinear features well such as limit cycle (LCO), which very dangerous for structure. Therefore, linear ROMs are not good enough cycles prediction and active control law design. A new ROM dynamically equation NPOD/ROM...
