Authors: Hu Ye Zhou , Zhang Lin , Liu Pai , Liu Xin Yuan , Zhou Ming
Published: March 2014

Large scale wind power penetration has a significant impact on the reliability of the electric generation systems. A wind farm consists of a large number of wind turbine generators (WTGs). A major difficulty in modeling wind farms is that the WTG not have an independent capacity distribution due to the dependence of the individual turbine output on the same energy source, the wind. In this paper, a model of the wind farm output power considering multi-wake effects is established according to the probability distribution of the wind speed and the characteristic of the wind generator output power: based on the simple Jenson wake effect model, the wake effect with wind speed sheer model and the detail wake effect model with the detail shade areas of the upstream wind turbines are discussed respectively. Compared to the individual wake effect model, this model takes the wind farm as a whole and considers the multi-wakes effect on the same unit. As a result the loss of the velocity inside the wind farm is considered more exactly. Furthermore, considering the features of sequentially and self-correlation of wind speed, an auto-regressive and moving average (ARMA) model for wind speed is built up. Also the reliability model of wind farm is built when the output characteristics of wind power generation units, correlation of wind speeds among different wind farms, outage model of wind power generation units, wake effect of wind farm and air temperature are considered. Simulation results validate the effectiveness of the proposed models. These models can be used to research the reliability of power grid containing wind farms, wind farm capacity credit as well as the interconnection among wind farms

A Constitutive Model of Rocks under Uniaxial Tension
Authors: Liu Dong Qiao
Published: March 2014

A constitutive model is proposed to simulate the completely deformation process of rocks under uniaxial tension. Based on the revised elastic modulus method derived from the hypothesis of strain equivalence, we analyzed the relationship between the damage variable and the strain. It is found that the relation can be modeled using a sigmoid curve. This model can describe the complete deformation process of rocks under uniaxial tension satisfactorily. In particular, the nonlinearity near the peak in the pre-peak region is accurately captured by the proposed constitutive model. The rapid decrease of rock strength after peak load can also be captured satisfactorily. The used mathematical function is simple and the damage evolution process is clear. The validity of the model is verified using laboratory test data.

In this work, simultaneous absorption of SO2and NO from N2-NO-SO2simulated flue gas using sodium chlorate as the additive and urea as the reductant was investigated experimentally in a rotating packed bed. In RPB, various rotational speeds, gas flow rates and liquid flow rates were studied by means of the removal efficiency of SO2and NO. The experimental results showed that the removal efficiency of SO2was higher than 99.00% under various experimental conditions and, at the same time, the removal efficiency of NO exhibited different results under various experimental conditions. The simultaneous NO removal efficiency of 82.45% and the SO2removal efficiency of 99.49% could be obtained under the N2flow rate of 0.5 m3/h, SO2flow rate of 6 mL/min, the NO flow rate of 4 mL/min, the rotational speed of 460 rpm and the absorbent flow rate of 40 L/h.

Over the past years, synthesis of pyrrole-imidazole (Py-Im) polyamides has been achieved by solution-phase and solid-phase methods. Comparing with solution-phase synthesis, the solid-phase synthesis has showed great superiority in various aspects. The solid-phase synthesis is a rapid, effective, energy-saving and environment-friendly method, which has been widely used in the synthesis of pyrrole-imidazole polyamides. Many complicated polyamides can be obtained quickly and effectively through this method. By far, the application of the solid-phase synthesis for Py-Im polyamides has made rapid development. Resin as the main carrier, a key substance in solid phase synthesis, consists of two parts: polymer (macromolecular resin) and linking chain (linker). To date, there are many kinds of resins applied in the solid phase synthesis, such as PAM resin, Wang resin, Oxime resin and Clear resin, and so on. In this article, we will focus on the elaboration about the basic principle and application of the four kinds of resins mentioned above in solid-phase synthesis of polyamides. This provides an important reference for development of polyamides.

It is clear that operational reliability of aircraft equipment is very important to aircraft. Because the equipment consists of a variety of components, their material properties can have a great influence upon improvement of operational reliability. In order to obtain better reliability of the equipment, selecting components of the equipment carefully must be done in material properties. Reliability theory FMECA is applied to improve operational reliability of the product. Based on the process of FMECA, all kinds of the failure mode, reasons, effects and criticality of the products can be determined completely. All selected components of the equipment may be confirmed in improving material properties finally. The results indicate that selecting component properly in material properties can be useful and effective for improving operational reliability of all equipments.

Published: March 2014

In the process of anaerobic digestion for methane production, one-third of which is from hydrogen, another two-thirds from acetic acid. From the point of material and energy recovery, the energy conversion efficiency of alone hydrogen or methane production is less than co-generation of hydrogen and methane production. Because hydrogen production is also accompanied by acidification and syntrophic acetogenic fermentation process, it is technically feasible for alone hydrogen or methane production. As the two-phase anaerobic digestion separate the acidifying bacteria and methanogens in different reactors, blocking the synergy of the two different microbial community, we should provide scientific and technological support for two-phase anaerobic application.

Published: March 2014

A new down-the-hole drill (DTH) position method based on binocular stereo vision was presented. In this method, a pair of stereo images containing holes marker were obtained by stereo cameras, which were then segmented by the fuzzy threshold method based on trapezoidal membership functions. The hole mark centre was extracted by image invariant moment principle. Then hole mark 3D locations can be calculated by triangulation principle. Finally, the autonomous position experiments based on binocular stereo vision system were implemented on DTH test-bed. The experiments results show that the binocular stereo vision system applied to DTH drill position is reliable, and the position error is within 25mm.
