【摘要】：能源紧张,促进可再生清洁能源产业的迅猛发展,太阳能就是其中之一,把太阳能转换为电能再传输到客户端使用,光伏变压器应运而生。光伏发电利用太阳能为发电能源,为此需要将光伏发电场建在日照时间长、日光照射强烈的西北地区,这些地区的环境都比较恶劣,远离市区,因此无人值班智能化的光伏变电站应运而生且快速发展。如何为用户提供合理化方案,如何快捷有效的合理的使用太阳能以及如何减少故障实现远程计算机操作控制,这就需要对光伏箱式变电站进行智能规化设计。依据智能变电站的发展趋势和光伏发电的特点,本文根据用户智能化的实际需求设计光伏发电专用智能箱式变电站。在统一的自动化平台上,建立起对箱式变电站各个分立系统及元件的综合管理、控制、保护、测量,实现在站控层可以了解箱式变电站的运行状况,电流、电压、负荷率等参数。本文根据光伏箱式变电站的结构特点将变电站划分高压侧、低压侧、变压器三个部分,“目”字形排列,配置相应在线状态检测设备,从而实现对间隔内元器件、保护装置、仪表、测控装置等设备进行优化,在保证供电质量和供电可靠性的情况下实现智能化,进一步提高光伏箱式变电站性价比。
[Abstract]:Energy shortage, promote the rapid development of renewable clean energy industry, solar energy is one of them, the conversion of solar energy to electricity and then transferred to the client for use. Photovoltaic transformers came into being. Photovoltaic generation uses solar energy to generate energy, so it is necessary to build photovoltaic fields in the northwest of China where the sun is long and the sunlight is strong. The environment in these areas is relatively bad. Far away from the urban area, the unattended and intelligent photovoltaic substation came into being and developed rapidly. How to provide the rational scheme for users. How to use solar energy efficiently and reasonably and how to reduce the fault to realize the remote computer operation control. This requires the intelligent planning design of photovoltaic box substation, according to the development trend of intelligent substation and the characteristics of photovoltaic power generation. This paper designs the special intelligent box substation for photovoltaic power generation according to the actual needs of users. On the unified automation platform, the integrated management and control of each discrete system and components of the box substation are established. Protection, measurement and realization in the station control layer can understand the operation status, current, voltage, load rate and other parameters of the box substation. According to the structural characteristics of photovoltaic box substation, the substation can be divided into high-voltage side and low-voltage side. The three parts of the transformer are arranged in the shape of "mesh", and the corresponding on-line state detection equipment is configured to optimize the equipment such as interspaced components, protective devices, instruments, measurement and control devices and so on. Under the condition of ensuring the quality and reliability of power supply, the performance and price ratio of photovoltaic box substation is further improved.
