In its future growth, national policy, or institutional factors will directly influence its direction of development. Employing new institutional economics' basic theories, this paper analyzes non-grid-connected wind power's evolution and development path choice from the view of institutional innovation and institutional change. Then a development mode of non-grid-connected wind power is put forth to accomplish the institutional change according to the characteristics of institutional changes. Under this mode, government should play an active role in economic efficiency and institutional construction to promote sustainable development of wind power.","PeriodicalId":171339,"journal":{"name":"2010 World Non-Grid-Connected Wind Power and Energy Conference","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115735470","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, some research efforts have been focusing on how to efficaciously reclaim more of the heat energy during the aluminum reduction process. In this study, we propose a new aluminum reduction cell structure with a lava thermo-exchanger. Three-dimensional thermal field analysis was carried out on the novel aluminum reduction cell with the lava thermo-exchanger. Analytical results show that the novel aluminum reduction cell structure can satisfy the actual requirement of the aluminum reduction industry and at the same time, it also has a high heat recycling efficiency.","PeriodicalId":171339,"journal":{"name":"2010 World Non-Grid-Connected Wind Power and Energy Conference","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123071316","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

But, offshore wind farms are difficult construction, with high requirements in the quality and reliability of wind power units, and rigorous requirements towards oppugning atrocious weather on the sea such as typhoons. Therefore, to develop offshore wind power healthily, rapidly, and in order, besides deeply studying and analyzing complicated wind resource and environmental conditions on the sea, the forceful technology support is indispensable. This article first analyzes connotation and general framework of construction system of offshore wind farms, then emphasizes the evaluation of wind resource on the sea and location of wind farm, high-power special wind turbine on the sea, installation of offshore wind farm, disembarking and transmission of sea wind, anti-typhoon and other natural disasters, as well as large scale application of wind power on the sea, to illustrate construction system of offshore wind farm, Finally a scientific basis and guidance is provided for large scale offshore wind farm building.","PeriodicalId":171339,"journal":{"name":"2010 World Non-Grid-Connected Wind Power and Energy Conference","volume":"351 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128027023","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Non-grid applications will be applied as well. Because of fluctuation of wind and solar power, integration of new energy including non-grid solutions were important to offer a steady consumption of power. Proper storage and comprehensive utilization of power were needed to make full use of power. Several types of storage of power was introduced and a certain example for Combined Heat and Power (CHP) was given in this paper. In Demark, combined heating/cooling and power system was used to make improvement of energy efficiency, in which hot water was used as medium. By district heating and CHP, the rate of energy effeciency was increased about 50%, compared with conventional power plants. Fossil fuel was replaced with biomass storage to solve the enviornmental problems. Average use of CHP was just 9%, so CHP could be developed greatly in the future.","PeriodicalId":171339,"journal":{"name":"2010 World Non-Grid-Connected Wind Power and Energy Conference","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124109756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
