Description

光伏嗅探器
技术领域
[0001] 本发明涉及电カ电子技术、电カ线载波通信技术、太阳能技术、太阳能发电技木、应用于太阳能并网和离网发电。
背景技术
[0002]目前太阳能发电主要是将多个太阳能电池组件串并联后,再与太阳能逆变器连接实现并网或离网发电。
[0003] 太阳能电站尤其是太阳能电池组件很容易发生故障,故障的原因可能是太阳能电池组件沾染灰尘、花粉、鸟粪、积雪,也有可能是安装缺陷、生产缺陷等等。
[0004] 因为太阳能电池组件串联在一起,串组里流过的最大电流取决于性能最差的太阳能电池组件。一个有缺陷或者损坏的太阳能电池组件,使这个串组里正常工作的其它太阳能电池组件性能同样变差。所以,判断太阳能电站的运行状况以及在大量的太阳能电池组件之中定位发生问题的太阳能电池组件,对于及时排除太阳能电站的故障,提高太阳能电站的发电效率显得非常重要。在这方面,目前缺少ー种简单、有效、低成本的方案来实现。
发明内容
[0005] 针对上述问题,本发明的主要目的在于提供ー种安装简便、低成本的光伏嗅探器(201),光伏嗅探器(201)直接安装在太阳能电池组件(101)的太阳能接线盒里。利用现有的电缆以电カ线载波通信方式传送数据,不需要增加额外的通信线缆,和现有的太阳能发电系统完全兼容。数字信号控制器(103)控制检测模块(104)对太阳能电池组件(101)的输出电压、电流进行检测,以及对太阳能接线盒的内部温度进行检测,当光伏嗅探器(201)接收到智能监控器(207)发出的上传数据指令吋,这些测量数据和太阳能电池组件(101)的序列号一起由通信模块(105)以电カ线载波通信方式经汇流箱(202)、直流配电柜(203),由逆变器(204)中继,传送到智能监控器(207),智能监控器(207)再通过路由器(208)从网络(209)将数据上传至监控网站服务器(210),监控网站服务器(210)根据太阳能电池组件(101)的电压、电流、温度来判定它是否工作正常。如果数据不正常,则产生报警提示,维护人员可以根据报警提示去检查及维护太阳能电池组件(101)。
附图说明
[0006] 图1为光伏嗅探器内部结构图。
[0007] 图2为光伏嗅探器的系统应用图。
[0008] 附图1:辅助电源(102)、数字信号控制器(103)、检测模块(104)、通信模块(105)。
[0009] 附图2:光伏嗅探器(201)、汇流箱(202)、直流配电柜(203)、逆变器(204)、交流配电柜(205 )、公共电网(206 )、智能控制器(207 )、路由器(208 )、网络(209 )、监控网站服务器(210)。具体实施方式
[0010] 在附图1中,光伏嗅探器(201)通过辅助电源(102)从太阳能电池组件(101)获取电源,产生稳定的直流电压,给数字信号控制器(103)、检测模块(104)、通信模块(105)供电。
[0011] 在极端情况下,当太阳能电池组件(101)被完全遮盖时,辅助电源(102)无法从太阳能电池组件(101)产生稳定的电压,其它模块也将无法正常工作,这时没有信号送往监控网站服务器(210),而同一时刻周围其它太阳能电池组件(101)工作正常,系统可以判定该太阳能电池组件(101)处于非正常工作状态。
[0012] 数字信号控制器(103)对检测模块(104)和通信模块(105)进行控制。
[0013] 检测模块(104)的输入端连接太阳能电池组件(101)的输出端,它由数字信号控制器(103)控制,每隔一定时间对太阳能电池组件(101)的输出电压、电流、以及接线盒的内部温度进行检测,检测结果暂时存储于内部存储器中。
[0014] 通信模块(105 )接收智能监控器(207 )发出的指令,将智能监控器(207 )传送过来的电力线载波信号解调成数字信号,然后将指令传递给数字信号控制器(103);当接收到智能监控器(207)的数据发送指令时,由数字信号控制器控制(103),将存储在内部存储器的检测数据,调制成电力线载波信号,上传至智能监控器(207 )。
