Wind energy efficiency (WEE) is used to estimate the net contribution of CO2 emission reduction from wind-generated electricity, which is an essential index to measure the efficiency of a power grid to accommodate wind energy. This paper takes into account that China's power grids mainly consist of coal-fired units, and it analyzes the cost components in accommodating wind power by means of unit commitment. This paper reveals how WEE changes with the operation modes and the parameters of coal-fired units, and the wind utilization proportion both in theory and by case study. The results show that the rules, approaches, prediction needs are quite unique in a coal power plant intensive grid. In addition, theory basics of wind-coal coordinating operation is provided in this paper. © 2013 State Grid Electric Power Research Institute Press.

This study investigates cracking resistance behaviors of ultra-high volume fly ash conventional dam concrete (UHVFACDC) at early age using a temperature-stress testing machine (TSTM), with a comprehensive consideration of temperature history, constraint, deformation and stress of concrete from the prospective of wholism to overcome the deficiency in the traditional methods of thermal cracking property evaluation of concrete at early age. The experimental results show that in comparison with the reference concrete, this fly ash concrete has lower hydration temperature rise, and cracking temperature and its cracking temperature drop is larger. And during hardening, it manifests a smaller coefficient of thermal expansion and a higher degree of tensile creep. All this indicates that UHVFACDC of great early-age cracking resistance is a promising type of green high-performance dam concrete. © 2016 All right reserved.

The paper aims to deal with the numerical simulation of cavitation phenomena inside the centrifugal pump and analyze the development of cavitation based on improved cavitation model, Standard k-ε and RNG k-ε turbulence model. When cavitation flow and non-cavitation flow were simulated and analyzed, the pressure of blades under incipient cavitation, developed cavitation and serious cavitation were gotten. The paper also gave the principle of incipient cavitation and divided the region into five cavitation regions based on bubble relative length. The results show that with the decreasing of inlet total pressure, bubble appears firstly in suction surface of the blade, and then moves along the blade profile, and next forms attached cavitation bubble. After this stage, bubble is gradually out of the mainstream movement and close to the pressure surface. Finally, the flow passage is filled with bubble, which hinders the flow. The number σ=0.3067 of incipient cavitation is a greater dimension hierarchy than that of σ=0.0281 under design condition. Seen from the impeller meridian plane, bubble appears firstly in the near the hub, goes towards forward cover plate, and attaches near the front cover. Cavitation in centrifugal pump is subdivided again into the five stages, that are incipient cavitation, critical cavitation, developing cavitation, complete cavitation, broken cavitation.

In situ diffusion experiments are performed in underground research laboratories for understanding and quantifying radionuclide diffusion from underground radioactive waste repositories. The in situ diffusion and retention, DR, experiment was performed at the Mont Terri underground research laboratory, Switzerland, to characterize the diffusion and retention parameters of the Opalinus clay. Several tracers were injected instantaneously in the circulating artificial water and were then allowed to diffuse into the clay rock through two porous packed-off sections of a borehole drilled normal to the bedding of the clay formation. This paper presents a single-site multicomponent reactive transport model of Cs+, a tracer used in the DR experiment which sorbs onto Opalinus clay via cation exchange. The reactive transport model accounts for the diffusive-reactive transport of 11 primary species and 22 aqueous complexes, and the water–rock interactions for 5 cation exchange and 3 mineral dissolution/precipitation reactions. Most of the solutes except for Cs+ diffuse from the Opalinus clay formation into the injection interval because the concentrations in the initial Opalinus clay pore water are larger than those of the initial water in the circulation system. Calcite dissolves near the borehole while dolomite precipitates. Dissolved Cs+ sorbs by exchanging with Ca2+ in the exchange complex. The computed dilution curve of Cs+ in the circulating fluid is most sensitive to the effective diffusion, De, of the filter, the selectivity coefficient of Na+ to Cs+, KNa–Cs and De of the borehole disturbed zone. The apparent distribution coefficient of Cs+, Kad, in the formation varies in space and time from 100 to 165 L/kg due to the temporal changes in the water chemistry in the formation. The results of a sensitivity run in which the initial chemical composition of the Opalinus pore water is the same as the initial chemical composition of the water in the circulation system show that the changes in Kad are negligible. The dilution curve of Cs+ computed with the reactive transport model coincides with that obtained with the Kd model. The tracer concentrations along the overcoring profiles computed with the Kd model, however, differ significantly from those computed with the reactive transport model. Therefore, a reactive transport model is needed for the appropriate interpretation of the Cs+ overcoring data from the DR diffusion experiment. © 2015, Springer-Verlag Berlin Heidelberg.

Activity handover within engineering construction projects is time consuming, takes longer than the actual activities, and therefore, can cause duration delays. This paper presents relay chain seamless handover (RCSH) technology, which is based on relay technology theory and actor-network theory. This study systematically elaborated the RCSH processes, activity relay flows, and methods to address balancing speed under varying conditions. Our analysis results indicate that as compared to traditional activity handover, RCSH improves handover quality and guarantees the duration. RCSH technology was successfully applied in the third phase of the Three Gorges Dam Project, specifically for its concrete construction duration and quality control. Through the use of RCSH, effective overall planning, and efficient coordination of various production links, along with seamless activity handover in the third phase of the project were accomplished— with no additional time consumed by the handover process—and the construction of a concrete dam without a crack was achieved. © Wang et al.

Foam glass production process is a typical nonlinear, large time delay, large inertia, strong cross-coupling, time-varying and complex control object. In this study, a new temperature control strategy is proposed by analyzing the working mechanism of the kiln and the temperature control problem in it. In the application, the Optimized Fuzzy Neural Network (OFNN) is applied to model the foam glass kiln and its weights and threshold value of the neural network are optimized by the Clonal Selection Algorithm (CSA) of the immune system theory. The structure of the controller is modified at any time in the process of production according to the temperature output error and its aim is to achieve the most stable temperature control of the foam glass production process in the kilns. The application of the model in the control system is successful and effective to improve the glass product quality. © 2013 Asian Network for Scientific Information.
