【摘要】：地球资源的日渐消耗,环境的不断恶化,使民众越来越关注并提倡绿色能源,而光伏发电作为这一新能源的代表,因其便于使用且绿色环保,受到越来越多的关注。现阶段的家用光伏发电系统首先是按照既定容量或用户自己申请的容量为用户安装相关设备,且没有依据大连地区居民实际用电需求进行分析,容易造成资源的浪费和成本的损耗；其次,现在居民用光伏发电系统的自动化水平低,设备自身程序无法满足普通用户需要；第三,现在居民家用光伏发电系统主要应用在顶楼或别墅用户,中间楼层的用户因没有足够的空间安装太阳能电池板,导致无法正常安装发电系统；该系统的投资成本高,对于普通收入的一般家庭来说,经济负担比较重。现在已经使用的家用光伏发电系统一般都直接并网,且安装蓄电池这一设备。针对安装条件受限,设备自动化程度低,造价成本过高等问题,通过进行实际情况调查和分析,本课题根据大连地区的地理位置特点和气象条件,通过对大连普通家庭的用电量情况、收入情况和家用电器情况的调查,设计一套适合普通家庭使用的光伏发电系统。并根据现在大连地区的住宅特点多以高层建筑为主,让该发电系统可以适用于中间楼层的居民,将普遍安装在顶楼的太阳能电池板安装于楼体侧面,并根据现阶段实行的建筑要求,设计具体的安装方式,并根据实际需要计算调整电池板的角度。可行性方面,因为上网销售电价和购买电价有较大电价差,因此增加蓄电池的设计,并针对家庭使用的特殊情况,对控制器的程序进行设计。同时结合光伏发电系统的造价成本和收益情况进行经济分析比较,致使光伏发电可以具有普遍性,更适合普通家庭,并在实际使用中更为切实可行。
[Abstract]:With the increasing consumption of the earth's resources and the deterioration of the environment, more and more people pay attention to and advocate the green energy. As the representative of this new energy, photovoltaic power generation is paid more and more attention because of its easy to use and green environmental protection. At the present stage, the household photovoltaic power generation system first installs the relevant equipment for the users according to the established capacity or the capacity applied by the users themselves, and does not analyze the actual electricity demand of the residents in Dalian area. It is easy to cause waste of resources and cost loss. Secondly, the level of automation of photovoltaic power generation systems is low and the equipment itself can not meet the needs of ordinary users. Third, At present, the residential photovoltaic power generation system is mainly used in the top floor or villa. Because the middle floor users do not have enough space to install solar panels, it is impossible to install the power generation system normally; the investment cost of the system is high. For ordinary income families, the financial burden is heavy. Household photovoltaic systems that are now in use are generally connected directly to the grid, and batteries are installed. In view of the problems of limited installation conditions, low automation of equipment, high cost and so on, through the investigation and analysis of the actual situation, this subject is based on the geographical location characteristics and meteorological conditions of Dalian area. Based on the investigation of electricity consumption, income and household appliances of ordinary households in Dalian, a photovoltaic power generation system suitable for ordinary households is designed. According to the current residential characteristics in Dalian area, most of the residential buildings are high-rise buildings, so that the power generation system can be applied to the residents of the middle floor, and the solar panels commonly installed on the top floor will be installed on the side of the building. According to the construction requirements of the present stage, the specific installation mode is designed, and the angle of the battery panel is calculated and adjusted according to the actual needs. In the aspect of feasibility, because there is a big difference in electricity price between selling price and buying price, the design of battery is increased, and the program of controller is designed according to the special situation of home use. At the same time, the cost, cost and income of photovoltaic system are analyzed and compared. The result shows that photovoltaic power generation can be universal, more suitable for ordinary families, and more feasible in practical use.
