A novel voltage fluctuation and flicker generating main circuit topology is proposed in this paper, combined with passive and active to realize voltage fluctuation and flicker. The fundamental frequency power is supplied by system source and the other frequency fluctuation power is supplied by active components, so the capacitor of generator is easy to realize larger because of lower active loss. Full-bridge diode rectifier is adopted to maintain the stable DC-bus voltage, the later inverter is controlled by instantaneous value voltage and current double closed-loop to make sure good static and dynamic performance. The inverter output two frequency voltage waveforms, and added to fundamental frequency sinusoidal voltage waveform by transformer so that the typical sinusoidal modulation voltage fluctuation and flicker waveform is obtained. The simulation model is set up on the platform of Matlab/Simulink. Finally, the simulation and experimental results show that the proposed main circuit and control strategy is feasible and efficient.
本文提出了一种新的电压波动和闪变产生主电路拓扑结构,将无源和有源相结合,实现电压波动和闪变。基频功率由系统源提供,其他频率波动功率由有功元件提供,因此由于有功损耗较低,发电机的电容容易实现较大。采用全桥二极管整流器保持直流母线电压稳定,后端逆变器采用瞬时值电压电流双闭环控制,保证了良好的静态和动态性能。逆变器输出两频电压波形,并通过变压器加入基频正弦电压波形,得到典型的正弦调制电压波动和闪变波形。在Matlab/Simulink平台上建立仿真模型。最后,仿真和实验结果表明了所提出的主电路和控制策略的可行性和有效性。

Based on the database of typical weather condition in northern cold region of China, this paper compares different function buildings’ cooling and heating load’s imbalance rate. The effect of different building functions on cooling and heating load is analyzed. On the above basis, underground heat exchanger pipe group model of ground source heat pump (GSHP) is established. As a monthly time step to change heat flux, the continuity change of soil temperature field around the tube is studied. Combined the above pipe group model, ‘soil representative accumulated temperature’ of buildings of different functions is obtained. According to this indicator, whether the GSHP is suitable for buildings of different function can be judged.

GCA-CG Based Groundwater Level Prediction with Uncertainty in Lower Reaches of Tarim River 基于GCA-CG的塔里木河下游地下水位不确定预测
Pub Date : 2009-10-16 DOI: 10.1109/ICEET.2009.380
Yue Chen, Yuhong Li
It is well known that no uniform prediction approaches were obtained regarding ground water level, though the neural network and some other so-called artificial intelligence methods consistently provide the smallest uncertainty and different medians warranting further research on their abilities. In the present paper, the lower reaches of Tarim River is taken as the study area, a grey correlation analysis and cloud generator (GCA-CG) based groundwater level prediction model is proposed. The most important characteristic feature of the novel model is that the observation data with uncertainty is taken into consideration. First of all, based on the GCA theory, the most important influencing indicator of groundwater level is selected. And then, the CG of knowledge reasoning is applied to predict the groundwater level. Finally, a numerical experiment based on the historical observation data is performed to verify the presented ground water level prediction model, which shows us that the fitting precision is 91.09% before water transportation and 87.84% after the water transportation. From the theoretic foundation and experiment results, we can see that the model could be widely used in other systems with uncertainty.
众所周知,虽然神经网络和其他一些所谓的人工智能方法始终提供最小的不确定性和不同的中值,但对于地下水位没有统一的预测方法。本文以塔里木河下游为研究区,提出了一种基于灰色关联分析和云发生器(GCA-CG)的地下水位预测模型。该模型最大的特点是考虑了观测数据的不确定性。首先,基于GCA理论,选取地下水水位最重要的影响指标;然后,将知识推理中的CG应用于地下水位预测。最后,利用历史观测资料进行了数值试验,验证了所建地下水位预测模型的拟合精度:输水前为91.09%,输水后为87.84%。从理论基础和实验结果可以看出,该模型可以广泛应用于其他不确定系统。

Based on the experiment of the phosphorus forms and the effect factors of phosphorus release from sediment in the urban shallow lake (taking Lake Xuanwu as a example)¿the results showed that when the water body had higher pH value during the excess alga period, phosphorus in the sediment was released deeply and the total dissolved phosphorus(TDP) was increased from 0.049mg/L to 3.255mg/L as 66 times as the origin concentration. The organic phosphorus(OP) in the sediment was transformed into inorganic phosphorus(IP) and became the important phosphorus forms that influenced the phosphorus release from sediment. The results also showed that the dissolved phosphorus(DOP) and alkaline phosphate(APA) in the sediment had positive correlated with the TDP of the water, which proved that microbial hasten the process of phosphorus release from the sediment. After the excess alga period ending, the pH value of waterbody would decrease slowly, phosphorus in sediment would not release any longer and sediment would become the collection of pollutants in the water environment again.
通过对城市浅水湖泊(以宣武湖为例)沉积物中磷形态及磷释放影响因素的实验研究,结果表明:藻过量期水体pH值较高时,沉积物中磷深度释放,总溶解磷(TDP)从0.049mg/L增加到3.255mg/L,是原浓度的66倍。沉积物中的有机磷(OP)转化为无机磷(IP),成为影响沉积物磷释放的重要磷形态。沉积物中溶解磷(DOP)和碱性磷酸盐(APA)与水体TDP呈正相关,说明微生物加速了沉积物中磷的释放过程。过量藻期结束后,水体pH值缓慢下降,沉积物中的磷不再释放,沉积物再次成为水环境中污染物的集合。

Pub Date : 2009-10-16 DOI: 10.1109/ICEET.2009.516
Hua Cai, An-na Shi
With the rapid growth of corporate in modern society, based on the enterprise level, we pay close attention to corporate social responsibility in no-market environment, and other related non-market strategy patterns on the level of the strategic management. In no-market environment, such as strict government control, by analyzing of game between main interests about Pollution of Electromagnetic Radiation, under the circumstance of the government making standard but not directly getting involved, we propose to analyze strategic CSR and no-market strategy by dynamic game tree. Furthermore, we propose that the corporate decides the corporate social orientation and invests in environmental protection by applying acts of no-market strategy, not just enhances the social image in more from the moral dimension of promoting competitive strength and enhancing product differentiation advantages.
随着企业在现代社会的快速成长,基于企业层面,我们密切关注非市场环境下的企业社会责任,以及战略管理层面上其他相关的非市场战略模式。在政府管制严格的非市场环境下,通过分析电磁辐射污染主要利益主体之间的博弈,在政府制定标准但不直接参与的情况下,提出用动态博弈树分析策略性企业社会责任和非市场战略。进而提出企业在环境保护方面的社会定位和投资是通过运用非市场战略行为来决定的,而不仅仅是从提升竞争实力和增强产品差异化优势的道德维度来提升企业的社会形象。

Aimed at the characteristic of MSWI fly ash in China that high content of chlorine, the volatilization of copper chloride (CuCl2) was studied. Firstly, the volatilization experiments of CuCl2 (about 28 mg) were carried out in a high temperature TG-DTA system, the considerable factors included atmosphere (Nitrogen and Air), heating rate (10¿/min, 15¿/min and 20¿/min) and different ratio of CaO/SiO2(mole ratio in 0.6, 0.8, 1.0, 1.2 and 1.4); Subsequently, the intrinsic kinetic model of CuCl2 volatilization was worked out. For experimental study the results show that: Two reaction peaks appeared in TG and DTG curves of CuCl2 volatilization; The volatilization rate of CuCl2 in Air atmosphere are lower than that in Nitrogen atmosphere obviously; The changing tendency of volatilization rate of CuCl2 with the increase of CaO/SiO2 is approximately U form. For Kinetics study the results show that: The two reactions can be described by 1-order kinetic model and 1/2-order kinetic modelin Nitrogen atmosphere, while 2/3-order and zero-order in Air atmosphere; The reaction order and activation energy all reduced with the increase of CaO/SiO2.
针对国内生活垃圾飞灰氯含量高的特点,对氯化铜(CuCl2)的挥发进行了研究。首先,在高温TG-DTA系统中对CuCl2(约28 mg)进行了挥发实验,主要影响因素包括气氛(氮气和空气)、升温速率(10¿/min、15¿/min和20¿/min)和CaO/SiO2的不同摩尔比(摩尔比分别为0.6、0.8、1.0、1.2和1.4);随后,建立了CuCl2挥发的本征动力学模型。实验研究结果表明:CuCl2挥发的TG和DTG曲线出现两个反应峰;CuCl2在空气气氛中的挥发速率明显低于氮气氛;CuCl2的挥发速率随CaO/SiO2的增加呈近似U型变化。动力学研究结果表明:两种反应在氮气气氛下均可描述为1级和1/2级动力学模型,在空气气氛下可描述为2/3级和零级动力学模型;随着CaO/SiO2的增加,反应级数和活化能均降低。
