Energy transfer within an arc is of crucial importance in numerous applications, such as thermal spraying and electric propulsion (arcjet magnetoplasmadynamic thruster). Its control will frequently determine the viability a process or device. However, lot numerical works done to model discharge using finite volume element method consider core only, while near-electrode layers are ignored replaced by presumed boundary condition. This greatly limits reliability simulation model. The goal this...
The modular multilevel converter (MMC) and energy storage are hot topics in the field of electrical engineering. versatile static synchronous machine (VSSM) is proposed by combining MMC storage, which can be used new type power systems with a large number non-synchronous electromechanical sources. In this paper, VSSM applied to DC transmission for offshore wind farm integration scheme based on power-frequency grid-following turbine, advantages as an inverter analysed. topology structure,...
A novel coupling procedure describing the complicated plasma-electrode interaction process has been developed and applied into 3D finite volume simulation of a direct current tungsten inert gas welding system. This is achieved by making space charge layer (sheath) incorporated computation domain interact with both bulk plasma cathode through effective electrical conductivity. Both chemical thermal nonequilibrium phenomena as well self-induced magnetic fields have taken consideration model to...
A high-scanning rate leaky-wave antenna (LWA) working at <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Ka</i> -band with continuous backward-to-forward beam-scanning capability, good open stopband (OSB) suppression and wide scanning angle is exhibited. The proposed LWA made by etching an array of cascaded high-Q resonators discontinuities on the substrate integrated waveguide (SIW). resonator designed combining two symmetrically unbalance...
Abstract To upgrade a wet flue gas desulfurization (FGD) wastewater treatment process in typical thermal power plant (TPP) Hunan province, China, new concept for reusing polyaluminum chloride (PAC)-based water sludge (WTPS) as coagulant is proposed. Results show that, an optimal WTPS dosage of 1,000 mg/L, the corresponding removal capacities suspended solids (SS) and chemical oxygen demand (COD) from practical FGD were 58.3% 40.3%, respectively. Through advanced with 50 mg/L PAC, pH 9,...
Steady-state 2D simulation of arc welding with a thoriated tungsten cathode and argon plasma is performed using finite volume method. It realized by self-consistent interaction model that includes chemical thermal non-equilibrium description an along 1D treatment sheath-bulk combination layer represented the boundary cells attached at cathode–plasma interface. A series comparisons experimental data show local effective value sheath conductivity current more constricted tip, leading to...
How to achieve economic and efficient grid connection of large-scale offshore wind power is currently a research focus. This article first proposes medium-frequency HVDC transmission scheme for distant farm integration, introduces the topology structure system. Subsequently, DC cable fault handling strategy suitable system was proposed on this basis, including configuration smoothing reactors multi-port circuit breaker side, energy dissipation devices, strategy. Finally, simulation model...
Flexible direct current (DC) transmission technology is adopted to offshore wind power system because it suitable for the scenario with long distance and large capacity. The converter station an important part of DC system, which can realize rectification by modular multilevel (MMC) or diode rectifier unit (DRU). collection farm adopt frequency medium frequency.
