Pneumatic conveying technology is an efficient, energy-saving and environmentally friendly means of solid feed conveying. In the process pneumatic conveying, wind speed has a decisive influence on characteristics. Here, computational fluid dynamics coupled with discrete element method simulation experiment were combined, was used as experimental variable to study characteristics material in tube, such particle distribution state, phase mass concentration, coupling force feed, average...
An antenna array is designed with 2×8 45-degree polarized stacked patches around 28 GHz in low temperature co-fired ceramic (LTCC) for the applications of fifth-generation wireless communication (5G). As demonstrated by measured reflection coefficient and realized gain response, bandwidth broadened when compared single-patch array. The proposed antenna-in-package (AiP) can operate from 26.3 to 29.8 GHz, maximum 15.1 dBi, 3-dB beamwidth 11° estimated efficiency 55%. Reasonable agreement...
The electrical capacitance tomography (ECT) technique uses the measured data to reconstruct permittivity distribution in a specific measurement area, which performances of reconstruction algorithms play crucial role reliability results. According Tikhonov regularization technique, new cost function with total least squares and ℓ 1 -norm based regularizer is presented, noises, model deviations influence outliers are simultaneously considered. split Bregman fast-iterative...
Improving the grid-regulating ability by coordinating resources is important when dealing with large-scale renewable energy (RE) accommodation contradictions. When considering status quo of resource endowment and market mechanism in China bilateral “source” “load” at grid-scheduling level, this study regarded flexible loads as “virtual interactive power plants” to participate balance reservation based on scheduling structure load aggregatorse. With objectives reducing curtailment, increasing...
In this paper we have applied TLM methods to the analysis of effects slot with structure overlapping and riveting on shielding effectiveness body. And verified its correctness from algorithm experiment. According simulation results, it is showed that handling a helps suppress leakage internal radiation cavity. We provided basis for modeling valve halls in HVDC calculate effectiveness.
We study a multi-period unit commitment problem under wind energy penetration, in which the load balance is enforced with predefined confidence level across whole system and over planning horizon.Since, except for special cases, chance-constrained problems are non-convex, we analyze two relaxations of based upon robust optimization ideas estimated quantiles marginal distributions net processes.The approximation proposals benchmarked against well-known scenario approximation.Under approach,...
With the development of power system, protection for electromagnetic interference is very important. Although protective measures electronic equipment are improved. But chassis itself shielded by existence defects (such as ventilation holes), leading to shielding performance decline. In this paper transmission line matrix method applied study signals couple in equipments electric system through aperture and interact with built-in PCB circuit, a rivet overlap connection model created, further...
