Abstract: This paper establishes a simulation model for a doubly fed induction generator (DFIG) connected with a power grid by using the vector control scheme. The model consists of a wind turbine, a doubly fed generator, power converters and a vector control strategy. The simulation model is built by using PSCAD/EMTDC. We also investigate the operating characteristics of a grid with the DFIG by considering respective wind speed fluctuation and short-circuit fault in the grid. Experiment results verify the correctness of the simulation model and the relative stability in the operating process of the simulated grid. This work provides a useful simulation platform for further studying the transient stability of the DFIG connected with power grid and more effective control strategies

Abstract: A hybrid evolution strategies algorithm based on dynamic demes is proposed in this paper. Evolutionary strategy algorithm is likely premature, and even simulated annealing with the character of local search is impossible to escape this range, when change the population based on the maximum entropy principle so that the individual out of this range, which can quickly converge to the global optimum. The numerical computation results indicate that the algorithm can gain higher global convergence rate and higher speed

Abstract: Emission trading means that, on the premise that environment and resources belongs to the nation and the total amount of emission is under regulation, the government sells the permit of a certain amount of emission to the polluter by issuing tradable emission licences. This paper discusses the emission trading in China in the recent 30 years. By reviewing the research field,research orientation and the status quo, this paper aimed at do some fundamental theoretical research on the application of the emission trading theory and the establishment of the emission trading market in China

Abstract: This paper presents the basic concept of waste and principal theory of hazardous waste management. While elaborating serious damages caused by solid waste, the paper also introduces relevant management policies of the US concerning hazardous waste. After the analysis of the current state of solid waste management in China, the paper proposes to accelerate the improvement of solid waste management system in our country. We are expecting a domestically effective solid waste management and an avoidance from similar pollution events overseas

Abstract: With the increasing application of information technology in the manufacture and design , vehicle performance has been improved constantly. The basic concept of vehicle information technology is first put forward, the significance of this research is analyzed, and a brief description of present domestic and international study condition is given. On the base of studies level at home , research contents of vehicle information technology is discussed and the application development tendency of vehicle information technology in vehicle is pointed out

Abstract: Under the background of the combination of design and management, the meaning and the role of design management are summarized. With the extensive application of information technology, a product design management system model based on information technology is proposed. The basic frame and the basic ideas of the system model are analyzed. The main technologies used by the new design management system are discussed. In a word, the new product design management system will be strategic resources and an inevitable choice in the process of developing new products

Abstract: As the economics developing, the traditional design can not meet the changeable customers demand. So the research on methods of new products design becomes valuable. In this paper, the methods of shoes style creation design were discussed. On the base of knowledge, several kinds of methods were put forward to realize shoes style creation design, including exciting creation-intelligence encouragement, expanding creation thought and way, analyzing style, reverse design, series design by analogy and judgment and part modification, reference and association. And a standard for shoes style creation design was also raised. The research mentioned above offers a new thought of shoes style creation design.

Abstract: For the current development position about logistics service of dangerous goods that the service link is single which mainly focus on warehousing and transportation sectors, as a consequence it factitiously separates the integrity of the entire supply chain services, from the perspective of supply chain integrator, this paper systematically analyses the advantage of high-end dangerous goods logistics service based on the supply chain integrator, besides, we also design a high-end dangerous logistics system in the comprehensive use of the FDID technology ,centering on the dangerous logistics center system, integrating the dominant resources, we aim at ensuring the security during the operation of dangerous goods logistics at utmost

Abstract: Based on data for the year in Heilongjiang Province, 1995-2009，Using co-integration and Granger causality test method to test causality between Heilongjiang Provincial Expressway Construction and industrial structure ,found that there exists co-integration relationship between the Heilongjiang Provincial Expressway Construction and operation and three industries. Finally, highway construction, relevant policy recommendations are given to adjust the industrial structure of Heilongjiang Province

Abstract: With the rapid development of China's economy, construction of the project has made rapid development，and the demand of modern construction materials for projects demanding is higher. High-quality engineering materials technology training is in engineering materials technology development to protect. Based on the analysis of high-quality construction materials and technical personnel on the basis of the basic characteristics, the author summarized the problems in the process of training engineering materials personnel in china and searched into the china engineering materials personnel training mode that includes the university of semi-structured model of teaching and the social talents’ life-long learning
