【摘要】：化石能源消耗引起的环境问题日益突出,风力发电作为技术最成熟的清洁能源在全球范围内得到迅速的发展和应用。近10年来,我国风电发展迅猛,风电装机已跃居全球第一。目前,风电资源富集的西北、东北和华北地区消纳风电的空间趋于饱和,光伏发电也进入大规模发展阶段,迫切需要跨区外送。文章分析我国风电运行面临的主要问题,对位于我国东北和西北地区的大型能源基地通过特高压直流工程实现风、光、火电力大规模、高效率、安全外送的可行性进行系统的分析研究。提出基于年度输电量和典型风、光发电曲线的配套电源装机容量优化计算方法和调度生产模拟方法及其安全经济运行的必要条件。并结合新疆哈密至河南郑州特高压直流工程进行分析计算,优化配套的装机容量,提出重大电网安全技术措施。研究结果表明,在保障电力系统安全稳定的基础上,通过优化风、光、火电装机容量可以最大限度地减少弃风、弃光容量,从而实现我国大型能源基地及其风电、光伏等清洁能源的集约高效开发和利用。对优化调整我国电源结构、加快治理大气污染、实现节能减排目标具有重要意义。
[Abstract]:The environmental problems caused by fossil energy consumption are increasingly prominent. Wind power as the most mature technology of clean energy has been rapidly developed and applied in the world. In the past 10 years, wind power in China has developed rapidly, and wind power installation has leapt to the first place in the world. At present, the space of wind power is saturated in the northwest, northeast and north of China, and photovoltaic power generation has entered the stage of large-scale development. This paper analyzes the main problems of wind power operation in China, and realizes the large-scale and high efficiency of wind, light and fire power through UHV DC project for the large energy base located in the northeast and northwest of China. The feasibility of safe delivery is analyzed and studied systematically. Based on the annual transmission volume and typical wind, the optimal calculation method of power supply installed capacity and the simulation method of dispatching production and the necessary conditions for safe and economical operation are presented. Based on the analysis and calculation of UHV DC project from Hami, Xinjiang to Zhengzhou, Henan province, the paper optimizes the installed capacity and puts forward important technical measures for power grid safety. The results show that on the basis of ensuring the safety and stability of power system, by optimizing the installed capacity of wind, light and thermal power, the abandoned wind and light capacity can be reduced to the maximum extent, so as to realize the large energy base and its wind power in China. Intensive and efficient development and utilization of clean energy such as photovoltaic. It is of great significance to optimize and adjust the power supply structure of our country, accelerate the control of air pollution and realize the goal of energy saving and emission reduction.
