This paper carried out the parative research on lightning protection of UHVDC transmission lines based ± 800kV project from Qinghai to Henan in China. According existed operating experience, flashover rate reference value for this was proposed. Two methods were used calculate whole line. One method statistical thunderstorm days, and other ground flash density. The results obtained by two mentioned above has been as engineering design.

Abstract A bench‐scale submerged membrane bioreactor (SMBR) was employed to treat vegetable oil plant wastewater with complete sludge retention. Treatment performance and fouling of the SMBR were investigated. The system stably removed high amounts total organic carbon, oil, ammonia from reduced chemical oxygen demand, demonstrating great potential in removing pollutants. layer not only governed by deposition substances composed extracellular polymeric like proteins, polysaccharides etc.,...

FQ highlights the difference between two EEMs of DOM from different units or under conditions in a wastewater treatment process and may usefully reflect behavior fate.

The wind turbine power converter is a critical system component due to relatively higher failure rates compared with the other sub-assemblies. lifetime of device in closely related its mean temperature and variations. In this paper, thermal cycling analyzed multi-physical model developed PSCAD, which includes detailed doubly-fed induction generator modeling, an electrothermal network semiconductors. loss obtained from PSCAD verified that software SemiSel. SemiSel however only shows average...

Energy storage (ES) station can be dispatched by the energy management system (EMS) to realize peak load shifting, frequency regulation and other control. According dispatch instructions, total charging discharging power is allocated among all units reasonably optimally. In this paper, a allocation method proposed. performance parameters operation parameters, instruction real-timely with minimum cost of ES as objective capacity that in next period also taken into consideration. Then respond...

Abstract Based on vehicle dynamic loading, the rut calculation method is put forward, influence law of pavement obtained, and rutting prediction for test road was performed by employing this method. The results indicated that there little difference between calculated value real one roads, maximum error 9 %. Moreover, their deformation shapes are almost same as a whole. Therefore, proposed feasible very complex problem calculation. under load studied using showed high temperature, heavy...

The passivity for discrete-time stochastic T-S fuzzy systems with time-varying delays is investigated. By constructing appropriate Lyapunov-Krasovskii functionals and employing analysis method matrix inequality technique, a delay-dependent criterion to ensure the considered established in terms of linear inequalities (LMIs) that can be easily checked by using standard numerical software. An example given show effectiveness obtained result.

This paper investigates the synchronization problem for neural networks with leakage delay and both discrete distributed time-varying delays under sampled-data control. By employing Lyapunov functional method using matrix inequality techniques, a delay-dependent LMIs criterion is given to ensure that master systems slave are synchronous. An example simulations show effectiveness of proposed criterion.

The state estimation problem is investigated for discrete-time Takagi-Sugeno fuzzy systems with time-varying delays. By constructing appropriate Lyapunov-Krasovskii functionals and employing matrix inequality technique, a delay-dependent linear inequalities (LMIs) criterion developed to estimate the some observed output measurements such that error-state system globally asymptotically stable. An example simulations given show effectiveness of proposed criterion.

In this paper, we present a new architecture for post-silicon validation called ISTA, Internal Signal Trace Analysis. The objective of ISTA is to give the bug location, including occurring time and place, during validation. consists an Error Detector, several hardware probes Probes (STPs) which are embedded in chip, off-chip Instruction Set Simulator (ISS). During validation, information acquired by STPs analyzed detect whether error has occurred if occurred, place bug. offers us ability...

A digital signal processor (DSP) system-on-chip (SoC) can be designed using a variety of architectures and techniques. This often presents different verification challenges compared to conventional SoC or designs. Verification such designs should take into account the goals applications DSP, how they are eventually used. paper proposes an application based methodology demonstrates this technique on real-life DSP design. Our employs library specially devised functions as test building blocks,...

Recently, rapid development of battery technology makes it feasible to integrate renewable generations with energy storage system (BESS). The consideration BESS life loss for different application scenarios is economic imperative. In this paper, a novel linear calculation model BESS-integrated wind farm in scheduled power tracking proposed. Firstly, based on the cycle times-depth discharge (DOD) relation-curve, coefficient unit throughput state charge (SOC) can be determined from times-DOD...
