400kw并网光伏发电站研究

摘要

面对全球日趋严重的能源危机问题，可再生能源的开发和利用得到了人们的高度重视。其中辐射到地球太阳能资源是十分富饶的，绿色清洁的太阳能不会危害我们的生存环境，因而受到了人们的广泛利用。光伏发电作为可再生能源被广泛的应用，技术不断革新。为了提高光伏发电系统的光电转换效率，需要系统实时的进行最大功率点跟踪。

由于国内人民生活水平的提高，科技不断地进步，控制不断地完善，导致不可再生能源消耗严重，甚至殆尽，从而促使可再生能源成为行业的主导。光伏发电成为现阶段一处亮丽的风景线，由于其拥有成熟的开发技术，成本相对较小，几乎无污染的优势，使得在新能源发电行业具有很高的前景，成为世界各国关注的焦点。同时，因为光照强度可变性、随机性以及不可控制性较强，光伏发电系统的稳定性影响较大。光伏发电行业不断革新，发电的数量越来越大。因此新一代的我们要认真去钻研光伏发电的影响。

现如今，全球都将遭受能源匮乏和大气污染严重得重大问题，在当前这种情况下，单相光伏并网逆变器控制系统成为世界各国关注的焦点和研发的重点方向。然而，单相光伏并网逆变器控制系统中的LCL型并网逆变器成为系统的重要角色，对电流的控制成为当前设计人员研究的重点方向。

Abstract

In the face of the increasingly serious global energy crisis, the development and utilization of renewable energy has attracted great attention.Among them, radiation to the earth's solar energy resources is very rich, green and clean solar energy will not harm our living environment, so it has been widely used by people.Photovoltaic power generation as a renewable energy is widely used, technology innovation.In order to improve the photoelectric conversion efficiency of photovoltaic power generation system, the system needs to track the maximum power point in real time.

Due to the improvement of people's living standard, the continuous progress of science and technology, and the continuous improvement of control, the consumption of non-renewable energy is serious or even exhausted, thus promoting the renewable energy to become the leading industry.Photovoltaic power generation has become a beautiful landscape at the present stage. Due to its advantages of mature development technology, relatively small cost and almost no pollution, it has a high prospect in the new energy power generation industry and has become the focus of attention of all countries in the world.At the same time, due to the variability, randomness and uncontrollability of light intensity, the stability of photovoltaic power generation system is greatly affected.The photovoltaic power generation industry continues to innovate, generating more and more electricity.Therefore, the new generation of us should seriously study the impact of photovoltaic power generation.

Nowadays, the whole world will suffer from the serious problems of energy shortage and air pollution. In this situation, the single-phase photovoltaic grid-connected inverter control system has become the focus of attention and the key direction of research and development all over the world.However, the LCL grid-connected inverter in the single-phase photovoltaic grid-connected inverter control system has become an important role of the system, and the current control has become the focus of current designers.

Keywords: Wind Photovoltaic power generation; Maximum power tracking; Inverter; DC/DC
