【摘要】：近年来,海上风电产业得到高度重视且发展迅速,成为最受青睐的新能源产业,但随着海上风电场的不断建设运营,对水域通航安全造成一定的干扰。虽然海上风电场不占用土地资源,但是作为海上较大面积的碍航物,它的存在对附近海域的通航环境造成不容忽视的影响,如海上风电场对附近港口、附近锚地、航道的干扰,对习惯航路、渔业养殖、海上油田及海底管线的影响等。海上风电场的建设在我国尚处于起步阶段,理论技术和实践经验匮乏,特别是对于近海风电场在通航安全方面的研究甚少,因此对海上风电场在通航安全方面的研究非常迫切和必要。鉴于此,本文从通航安全角度出发,在风电场工程规划前期进行海上风电场场址优选,从各规划场址中选择对通航安全影响最小的场址进行风电开发建设,前瞻性得降低风电场工程对通航安全造成的影响。首先分析了海上风电场影响通航安全的因素,包括水文气象、港口环境、交通环境、安全保障和其他因素,并结合风电场特点及通过分析和专家咨询筛选指标并确定优选指标体系。为了充分反应决策者的主观经验与偏好和客观信息之间的差异,本文采用层次分析法和熵值法组合赋权方式确定优选指标的权重,进一步运用灰色关联分析法获得各场址指标值与理想值的关联系数,最后应用灰色综合优选模型对规划场址排序优选。本文以唐山海域的四个规划风电场场址为实例,运用构建的优选模型对其进行排序优选,结果表明本文海上风电场场址优选模型得到了较好的应用,为以后各水域海上风电场规划场址的开发建设顺序提供决策参考。
[Abstract]:In recent years, offshore wind power industry has been highly valued and developed rapidly, becoming the most favored new energy industry, but with the continuous construction and operation of offshore wind farms. Although the offshore wind farm does not occupy the land resources, as a large area of sea obstruction, its existence of navigation environment in the nearby sea area can not be ignored. For example, the disturbance of offshore wind farm to the nearby port, nearby Anchorage, waterway, the influence on customary navigation, fishery breeding, offshore oil field and submarine pipeline, etc. The construction of offshore wind farm is still in its infancy in our country. Lack of theoretical technology and practical experience, especially for offshore wind farm in navigation safety research is very little, so the offshore wind farm in navigation safety research is very urgent and necessary. In view of this. From the point of view of navigable safety, this paper selects the site of offshore wind farm in the early stage of wind farm project planning, and selects the site that has the least influence on navigation safety to develop and build wind power from each planning site. Firstly, the factors influencing navigation safety of offshore wind farm are analyzed, including hydrometeorology, port environment, traffic environment, safety protection and other factors. In order to fully reflect the difference between the subjective experience and preference and objective information of decision makers, the characteristics of wind farm and the selection index system are determined through analysis and expert consultation. In this paper, AHP and entropy method are used to determine the weight of the optimal selection index, and the grey relational analysis method is used to obtain the correlation coefficient between the site index value and the ideal value. Finally, the grey comprehensive optimal selection model is applied to the priority selection of the planning sites. This paper takes the four planned wind farm sites in Tangshan sea area as an example, and uses the constructed optimal selection model to sort and select the sites. The results show that the optimal selection model of offshore wind farm site is well applied in this paper, which provides a decision reference for the development and construction sequence of offshore wind farm planning site in each water area in the future.
