20兆瓦光伏发电项目工程35kV送出线路EPC工程(论文16000字)
摘 要
新形势下，电力调度中依然存在一些安全隐患，要多措并举地做好电力调度的安全管理。文中论述了电力调度安全管理中存在的主要问题，电力调度安全管理的实现途径。随着市场经济的不断发展,电力体制改革不断深入,越来越多的电力企业开始转变自身的职能,由专供生产转向了营销服务,适应市场经济的发展。
本课题主要研究了光伏发电的应用是落实科学发展观、改善能源结构、抗灾设计原则及主要思想促进我国新能源开发利用的示范性项目,符合国家的产业政策和优化 能源结构、保护环境、减少温室气体排放、节约能源的要求。对促进我国太阳能光伏发电技术的开发与利用,推进光伏产业发展具有非常重要的意义。报告由本项目的背景出发，通过对建设必要性和可行性进行的深入分析和说明，得出本项目建设是可行的，并对方案和工程费用做了简单阐述，通过合理的费用、对线路的规划，设计基本风速，设计覆冰厚度导线的设计应力及安全系数光缆的选择，在光缆的选择上，铝包钢绞线机械性能好、抗腐蚀能力强、投资又不高，因此本工程推荐采用铝包钢绞线作为架空地线，这也是为了确保大数据战略方案中供电基础建设的实施，此项目的实施不仅节省了有色金属，还降低电能损耗和电压损失，提高供电的可靠性，对促进政务信息资源互联互通，提高党委、政府整体管理和服务水平，也有着非常重要的意义。

Abstract
Under the new situation, there are still some hidden dangers in power dispatching, so we should do well in the safety management of power dispatching. This paper discusses the main problems existing in the safety management of power dispatching and the way to realize the safety management of power dispatching. With the continuous development of the market economy and the deepening of the reform of the power system, more and more electric power enterprises begin to change their functions, and turn from special production to marketing services to adapt to the development of the market economy.
The application of photovoltaic power generation is a demonstration project to implement the Scientific Outlook on Development, improve the energy structure, the principle of disaster resistance design and the main ideas to promote the development and utilization of new energy in China. It is in line with the national industrial policy and the optimization of the energy structure, the environment protection, the reduction of temperature room gas emission and energy saving. It is of great significance to promote the development and utilization of solar photovoltaic technology and promote the development of photovoltaic industry. The report from the background of the project, through the in-depth analysis and explanation of the necessity and feasibility of the construction, the project is feasible, and a simple exposition of the project and engineering costs, through reasonable cost, the planning of the line, the design of the basic wind speed, the design of ice covered wire design stress and The selection of the safety coefficient optical cable, in the selection of the optical cable, the aluminum clad steel strand has good mechanical properties, strong corrosion resistance and low investment. Therefore, the aluminum clad steel strand is recommended as the overhead ground wire in this project. This is also to ensure the implementation of the power supply infrastructure in the strategic plan of large data. The implementation of this project not only saves the project. Nonferrous metals also reduce power loss and voltage loss and improve the reliability of power supply. It is also of great significance to promote the interconnection of government information resources and improve the overall management and service level of the Party committee and the government.
