光伏供电在5G通信基站建设中的应用研究发布时间：2023-03-07T09:25:57.010Z 来源：《中国建设信息化》2022年10月20期作者：王军伟[导读] 本文主要对光伏供电在5G通信基站建设中的应用进行分析与研究，以供同仁参考。
王军伟中国铁塔股份有限公司广东省分公司摘要：本文主要对光伏供电在5G通信基站建设中的应用进行分析与研究，以供同仁参考。
关键词：5G基站；电力供应；光伏供电；方案研究一、前言随着5G大规模应用普及，5G基站的覆盖场景也不断拓展，其建设形式更多的由传统的宏基站、室分、微基站、可附建的资源更广等，而一直以来基站的建设就面临着征址难、基站功耗大等系列问题。
为了更好地解决基站功耗大的问题，光伏发电与电能相结合，可以解决光伏发电输出功率不稳的问题，并能平滑电力输出，提高光伏发电的质量。
二、在5G通信基站建设中光伏供电建模光伏组件是太阳能转化为电能的核心部件，由若干单体电池串、并联连接和严密封装成组件，太阳能转化为电能的效率取决于光伏组件原材料及技术参数要求。
光伏组件从原材料上分为单晶光伏组件和多晶光伏组件，符合通信基站供电的电池片数量一般有48片、60片、72片、120片，组件容量（峰值功率Wp）为250~445Wp。
一定数量光伏组件按照系统的总功率需求组合成太阳能方阵为通信基站系统供电，太阳能方阵总功率计算如下：太阳能方阵总功率QP=负载功率QW×用电时间(HE)/日照峰值时间(HS)/损耗系数R式中，负载功率QW由通信基站设备负载功耗确定；用电时间根据夜间（HE）（阴雨天最低日照时间）确定；日照峰值时间（HS）根据基站所在位置的日照时长确定；损耗系数R默认按照0.75取值。
三、在5G通信基站建设中光伏供电系统组成光伏发电是利用半导体界面的光伏效应将光能直接转变为电能，通过计算用电时间和充放电时间，按照基站功耗需求适当配置由光伏组件组成的太阳能方阵进行发电及储能电池组，从而实现不间断的为基站进行供电，其组成如图1所示。

太阳能是目前最具前景的新型能源：用之不竭，且太阳能的使用不会破坏地球生态及环境；安全，无污染，利用成本低，且不受地理条件限制。
太阳能利用的形式多种多样，其中太阳能电池技术可将太阳能直接转换为电能，被认为是最有效的利用太阳能的方式。
太阳电池发电具有很多优点，如安全可靠，无噪声，无污染等，这些优点是常规发电和其他发电方式所不及的。
太阳能电池的分类有很多种，按用途分有航天用电池和民用电池，按其结构可分为晶体电池（单晶Si、多晶Si）、薄膜电池、化学太阳能电池、多元化合物薄膜太阳能电池等。
目前市场上的太阳能电池主要是硅基太阳能电池，其中又以多晶硅太阳能电池为主流。
然而，能够提供太阳能电池用的高纯硅厂家主要在国外，包括美国、日本和德国，且近年来多晶硅原料已经明显出现市场缺口，由此带来了其价格的迅速攀升。
东方日升电池片技术规格书一、东方日升电池片技术规格书引言概况1.1 东方日升电池片技术规格书是指建设东方日升电池片技术规格书的建设成本，即预期开支或实际开支的东方日升电池片技术规格书的全部费用。
东方日升电池片技术规格书建设周期长、投资大、协作部门多，在东方日升电池片技术规格书方面，具有单件性、多次性（投资估算、设计概算、东方日升电池片技术规格书预算、竣工结算）、方法的多样性及依据的广泛性、复杂性等特征。
目前，由于东方日升电池片技术规格书全过程、全方位投资管理的理念尚未形成，东方日升电池片技术规格书的各个阶段及环节制度和措施不够完善，脱节严重，导致东方日升电池片技术规格书中损失浪费现象比较普遍。
造成这种状况的主要原因是，在东方日升电池片技术规格书过程的各个阶段（包括投资决策阶段、东方日升电池片技术规格书设计阶段、招投标阶段、施工管理阶段及竣工决算阶段），造价控制仍存在诸多问题。
1.2 长期以来，我们对东方日升电池片技术规格书的理解往往只停留在预结算上，对东方日升电池片技术规格书管理缺乏全面而系统的定位，缺乏全过程、全方位、动态的管理。
对东方日升电池片技术规格书的控制，主要侧重于审查施工图预算和对竣工结算进行审核，对其他阶段的控制显得薄弱。
据有关部门资料数据分析：在东方日升电池片技术规格书的投资决策和设计阶段，影响东方日升电池片技术规格书东方日升电池片技术规格书造价的可能性为30%～75%，而在建设施工阶段，影响东方日升电池片技术规格书的可能性仅为5%～25%。
由此可见，将控制东方日升电池片技术规格书的主要精力放在东方日升电池片技术规格书建设中、后期的做法无疑是缺乏依据和有失全面的。
因此，要实现东方日升电池片技术规格书合理有效的控制，及东方日升电池片技术规格书投资最佳的社会和经济效益，就必须抓住重点，使东方日升电池片技术规格书管理工作始终贯穿于东方日升电池片技术规格书的全过程，实行全方位、全过程的科学系统的管理。

太阳能电池片作为中间产品，既可单独销售，也可作为下游产品组件和灯具原材料。
太阳能电池片在发行人产品结构中占据核心地位，生产电池片有较高的技术要求和较高的科技含量。
电池片光电转换效率、生产过程中的破碎率、日产能等技术指标的高低，将直接影响下游组件产品的输出功率和制造成本，进而影响组件产品的市场竞争能力。
主要产品的功能与用途行业主要竞争对手情况我国太阳能电池片生产企业相对比较集中，2008 年度前五家企业的产量占全国总产量的56.74%，前十家企业产量占全国总产量的78.72%。
报告期内，发行人市场份额逐年增加，2006 年-2008 年我国太阳能主要生产企业及其市场份额的情况如下表所示：主要产品及工艺流程图二、主要市场概况截至2009 年12 月31 日，发行人主要用自产电池片生产组件；用生产电池片、组件过程中产生的低效片、破碎片作为生产灯具材料的主要来源；电池片销售收入主要由于发行人根据市场上交易性机会进行部分电池片的销售。
上述三种产品的收入合计占主营业务收入的比重达100%，具体明细如下表：三、主要竞争优势工艺技术改造优势东方日升非常重视对技术研发的投入和自主创新能力的提高，通过引进人才，联合高校和科研院所等方式形成了专业稳定的科研队伍。

The ground wire and frame will be reliable grounding through the reserve grounding holes, by the installation bolts M5X10 ~ 15 matching plain washers, spring washers and nuts. Modules and ground cables shall be connected perfectly by wiring nose. Negative grounded inverters can be installed to prevent PID phenomenon.7.4 Where common grounding hardware (nuts, bolts, star washers, spilt-ring lock washers, flat washers and the like) is used to attach a listed grounding/bonding device, the attachment must be made in conformance with the grounding device manufacturer's instructions.7.5 Common hardware items such as nuts, bolts, star washers, lock washers and the like have notbeen evaluated for electrical conductivity or for use as grounding devices and should be used onlyfor maintaining mechanical connections and holding electrical grounding devices in the proper position for electrical conductivity. Such devices, where supplied with the module and evaluated through the requirements in UL 1703, may be used for grounding connections in accordance with the instructions provided with the module.7.6 The electrical connection shall conform to local electrical laws and regulations, "Y" type electrical connection mode is not allowed in module system electrical connection.7.7 Modules are equipped with bypass diodes（rated voltage 45V, rated current 20A）; improper installation may damage diodes, cables or wiring box.7.8 Please wrap the connectors after taking out the modules without immediate installation so as to prevent damage caused by wind or rain. Use of lubricant for connectors is prohibited, because it leads fracture of connectors.7.9 Do not remove the waterproof rubber rings out of the junction box or connectors.7.10 Use of diesel oil for heating is strictly prohibited at installation site, which may lead to connector failure because the gas after combustion of diesel and other petroleum products.8 Maintenance8.1Modules need to be inspected and maintained regularly, check all electrical connections to ensure that there is no open circuit and well connected.8.1.1 Check the open circuit voltage of each module:8.1.2 Covered the modules completely by non-transparent material.8.1.3 Disconnect the wire terminals8.1.4 Remove the non-transparent material off the modules; check and measure the terminal open circuit voltage.8.1.5 If the measured voltage is reduced by 1/4, it supposed to be bypass diode damaged. Please test the bypass diode performance.8.2 It’s recommend that adopt the following maintenance to ensure the modules maintain the best performance:8.2.1 Check whether the modules have appearance defects: whether the surface of the modules are damaged or abnormal, whether the modules are occluded by objects, whether the fixing between the modules and the frame is loose or not, and contact qualified or experienced maintenance personnel to adjust or repair after finding the abnormalities.8.2.2 Clean modules once a year as much as possible, depending on local conditions. When dirt appears on the surface of modules, it will reduce the power generation. When cleaning, a soft sponge or a rag can be used to wet the glass surface of the modules. A mild, non-abrasive detergent can be used to remove fouling. The use of corrosive chemical cleaners is strictly prohibited. In order to reduce electric shock or burns, it is recommended to clean modules in the morning or evening.8.2.3 Mechanical and electrical checks are required every six months to ensure the modules’ connectors clean and reliable connected.And ensure good electrical connection and no corrosion.8.2.4 It need ask qualified person to check the modules if have any doubt on the modules.8.2.5 Please note that all maintenance instructions, such as brackets, charging rectifier, invertersand batteries, shall be complied.9 Meaning of crossed –out wheeled dustbin:Do not dispose of electrical appliances as unsorted municipal waste, use separate collection facilities.Contact your local government for information regarding the collection systems available.If electrical appliances are disposed of in landfills or dumps, hazardous substances can leak into the groundwater and get into the food chain, damaging your health and well-being.When replacing old appliances with new ones, the retailer is legally obligated to take back your old appliance for disposals at least free of charge.10 Disclaimer of LiabilityBecause the use of the manual and the conditions or methods of installation, operation, use and maintenance of photovoltaic (PV) product are beyond the control of Lianyungang Shenzhou New Energy Co.,Ltd.
