本文选题:蒙西 + 弃风 ; 参考:《华北电力大学》2017年硕士论文
【摘要】:目前,我国正在大力发展风力发电项目,在国家政策的支持下,蒙西地区风力发电项目发展迅速,但是同时产生了弃风问题,导致了风能资源的大量浪费。本文首先结合蒙西地区的电网和地域的特点分析了蒙西地区弃风现象发生的原因,结合蒙西地区冬季供热热量需求量大的特点,提出了使用弃风供热的方案来消纳风电,提出了风电供热的具体实施方案。最后从节煤效益和经济效益角度分析了风电供热系统的可行性和实行条件。调查研究了蒙西电网的风电弃风惊人的事实,分析了我国蒙西地区目前存在的风电消纳问题,考察了国内外解决弃风问题的成功经验。分析了我国蒙西地区、内蒙古自治区乃至全国风电的发展近况,总结了蒙西风电产业在发展过程中具有的特点,给出了蒙西地区大规模弃风现场产生的原因。介绍了风力发电的基本原理,基于此得到蒙西地区风能开发潜力巨大,肯定了治理弃风问题的重要性。在集中供热和电热锅炉的基础上,介绍了风电供热的基本原理。最后,提出了蒙西地区可以实行的风电供热具体方案,给出了供热公司和电力系统改造方案,从而肯定了风电供热实施的可行性。最后,依据热力学和经济学原理分析了风电供热的节煤效益和经济效益,从而给出了风电供热可以实施的热力学和经济学条件。从经济上来讲,风电供热对于供热公司总是不利的,风电供热要得到发展,风电场与供热公司需要合作,共同讨论利益分配的问题,才能真正的实现双赢。
[Abstract]:At present, China is vigorously developing wind power projects. With the support of national policies, wind power projects in Mengxi region are developing rapidly, but at the same time, the problem of wind abandonment has resulted in a large amount of waste of wind energy resources. In this paper, firstly, considering the characteristics of power grid and region in Mengxi area, this paper analyzes the causes of wind abandonment phenomenon in Mengxi area, combined with the characteristics of large heat demand for heating in winter in Mengxi area, and puts forward a scheme of using abandoned wind to heat supply to absorb wind power. The concrete implementation scheme of wind power heating is put forward. Finally, the feasibility and implementation conditions of wind power heating system are analyzed from the point of view of coal saving benefit and economic benefit. This paper investigates and studies the astonishing fact of wind power abandonment in Mengxi power grid, analyzes the problem of wind power consumption in Mengxi area of China at present, and investigates the successful experience in solving the problem of wind abandonment at home and abroad. This paper analyzes the recent development of wind power in Mengxi region, Inner Mongolia Autonomous region and even the whole country, summarizes the characteristics of the wind power industry in the process of development, and gives the reasons for the large-scale abandonment of wind in the area of Mengxi. The basic principle of wind power generation is introduced. Based on this, the great potential of wind energy development in Mengxi area is obtained, and the importance of harnessing the problem of abandoned wind is confirmed. On the basis of central heating and electric heating boiler, the basic principle of wind power heating is introduced. Finally, the specific scheme of wind power supply in Mengxi area is put forward, and the retrofit scheme of heating company and electric power system is given, and the feasibility of wind power heating is confirmed. Finally, based on the thermodynamic and economic principles, the coal-saving and economic benefits of wind power heating are analyzed, and the thermodynamic and economic conditions for wind power heating are given. From the economic point of view, wind power supply is always unfavorable to heating companies. Wind power supply should be developed. Wind farm and heating companies need to cooperate to discuss the distribution of benefits together, in order to achieve a win-win situation.
