技术领域
本发明涉及太阳能光伏发电***,特别是一种具有监测功能的家用型太阳能光伏发电***。
背景技术
太阳能光伏发电技术是人类向太阳索取电能的重要途径。利用太阳能光伏发电***(以下简称PV***)规模可大可小的特点,把该技术推广应用到普通家庭,发挥家用PV***的就地发电就地使用、减少输电损失、故障就地解决的优点,将更能体现光伏发电技术的综合经济效益。如能充分利用家用PV***的优点,大力推广并网型家用PV***,则对建设资源节约型和环境友好型社会具有极大的价值和社会效益。
国外对家用PV***的应用技术有众多研究,其内容有带蓄电***的并网型,光伏融入建筑的建筑一体化型以及对***性能和太阳辐射的检测等。我国在家用PV***方面也做了多年的研究与开发。现在太阳能使用比较普遍,如何更好地监测太阳能发电***,看其是否稳定并入电网,则对光伏发电业务的开展有很大的帮助。
发明内容
本发明的目的在于克服现有技术的不足,提供一种设计科学合理,通过GPRS DTU数据传输进行配置和建模,实现数据读写、报告、日志以及监测等服务。
本发明解决其技术问题是采取以下技术方案实现的:
一种具有监测功能的家用型太阳能光伏发电***,包括光伏方阵、并网逆变器、交流开关箱、交流输出计量电度表及电缆,在光伏方阵上通过电缆连接有并网逆变器,在逆变器上连接有交流输出计量电度表,在交流输出计量电度表上连接有交流开关箱,其特征在于:在与光伏方阵相平行的位置上依次设置有太阳能辐射仪及环境气温仪,还包括一数据采集处理机构,该数据采集处理机构通过通信电缆与并网逆变器相连接。
本发明的优点和积极效果是:
1、本具有监测功能的家用型太阳能光伏发电***,通过对用户光伏发电***进行有效监测,及时发现引起发电上网引起电网波动的干扰因素,并实时监测光伏设备的发电量、上网电量是否存在异常,并采取相应管理措施,有效提高并入电网的稳定性,不仅对用户还是供电企业以及后续光伏发电业务的开展都有很大的帮助。
2、本发明结构设计科学合理,通过数据传输进行配置和建模,实现数据读写、报告、日志、文件以及监测等服务,可以有效地监测家用光伏发电***以及实现发电上网对电网的影响,是一种具有较高创新性的具有监测功能的家用型太阳能光伏发电***。
附图说明
图1为本发明的结构示意图。

具体实施方法
下面结合附图、通过具体实施例对本发明作进一步详述。以下实施例只是描述性的,不是限定性的,不能以此限定本发明的保护范围。
一种具有监测功能的家用型太阳能光伏发电***,包括光伏方阵1、并网逆变器2、交流开关箱4、交流输出计量电度表3及电缆,在光伏方阵上通过电缆连接有并网逆变器,在逆变器上连接有交流输出计量电度表,在交流输出计量电度表上连接有交流开关箱,其创新之处在于:在与光伏方阵相平行的位置上依次设置有太阳能辐射仪10及环境气温仪9,还包括一数据采集处理机构8,该数据采集处理机构通过通信电缆与并网逆变器相连接。
使用时,将本太阳能光伏发电***与负载7连通,太阳能辐射仪安装在太阳电池方阵的同一平面上,即安装倾角也为25°,全年太阳能日辐照量最大值和最小值是设计离网型PV***的重要参数,由于与PV发电量直接相关,因此也可供电网调度部门参考,瞬时最大太阳辐照度与PV***的逆变器等电气部件容量、耐压、抗过载能力设计有关,且是扰动电网的一个因素阴天的日辐照量分档,再列出持续的天数和累积辐照量,供设计蓄电池容量时参考。在严重阴雨天(太阳能日辐照量<500W·h/m2d)的日子里,光伏发电保证率几乎接近于零。换言之,在没有其他辅助发电设备(风力发电、柴油机发电等)的情况下,并网型PV***的负载将几乎完全依靠电网电源6供电(可由与负载相连的电度表5观察出)。对于一个完全由PV***供电的负载(路灯、庭院灯等)来说,会发生蓄电池连续三天放电而得不到充电的情况。因此通过数据传输进行配置和建模,实现数据读写、报告、日志、文件以及监测等服务,可以有效地监测家用光伏发电***以及实现发电上网对电网的影响。
尽管为说明目的公开了本发明的实施例和附图,但是本领域的技术人员可以理解:在不脱离本发明及所附权利要求的精神和范围内,各种替换、变化和修改都是可能的,因此,本发明的范围不局限于实施例和附图所公开的内容。
