      近年来,随着国内外大批的太阳能光伏电站的建立和并网发电,作为光伏发电的关键设备光伏并网逆变器具有广阔的市场前景。
        本文主要介绍WEINVIEW触摸屏在太阳能光伏并网逆变器中的应用,在这个系统中,触摸屏和逆变控制器通信,完成相关的数据采集,资料的保存,报警信息的登录,图文并茂显示逆变器运行参数和实时状态,并通过485或以太网和上位计算机进行远程通讯,实现整个并网电站的实时监控和调配。
        关键词:光伏 逆变器 触摸屏 DSP
        1 引言
        随着全球经济的迅猛发展,各行业能耗加剧,石油、煤炭等传统化石能源日趋枯竭。世界各国都把目光投向了可再生能源,希望可再生能源改变人类的能源结构,维持长远的可持续发展。在可再生能源中,太阳能以其独有的优势而成为人们关注的焦点。太阳能是取之不尽、用之不竭、无污染的绿色能源。世界各国都在投入巨资建设大规模的太阳能发电站。我国在光伏研究和产业方面也取得了较快的进展,2006年1月1日实施的《可再生能源法》,标志着太阳能发电已纳入我国的能源发展规划之中。根据2007年9月发布的《可再生能源中长期发展规划》,2020年,我国太阳能发电设备累计装机容量将达到2000MW 。
        太阳能光伏并网逆变器是整个光伏发电系统中最为关键的设备之一,它是把太阳能电池板产生的直流电能转换为交流电能的设备,运行过程中需要多个参数进行监测、计算、显示、记录、保存、报警等处理,需要和上位计算机、逆变控制器、无线GPRS模块进行通讯,实现数据交换。本文主要讲述WEINVIEW触摸屏在太阳能光伏并网逆变器中的应用。
        2 系统原理和方案设计
        太阳能光伏并网逆变器是把太阳能电池板通过光伏效应产生的直流电能进行逆变,转换成同电网同频率、同相位的交流电,接入电网对外进行输电。逆变器运行中要把测量的实时参数送给触摸屏,进行显示、记录等操作,也可和上位机通讯进行远程监控功能。系统结构图如下图所示:
        图1 系统结构图

        3 WEINVIEW画面设计要求
        本系统采用WEINVIEW MT8100I型号触摸屏,高品质10寸宽屏设计,LED背光模组;采用400MHz RISC CPU,使运行速度更快;内置电源隔离保护器,提高了产品的抗干扰能力,适应复杂环境下运行;多种标准的通讯接口和网络协议,方便用户使用;大容量的数据存储功能,并且可以直接存储或备份到U盘、SD卡或上位机上,满足逆变器运行过程中产生的海量数据信息。
        3.1 触摸屏主界面设计
        主界面显示逆变器运行的各种运行参数:PV电压、PV电流、A、B、C三项交流电压和电流、功率因数、电网频率、输出功率、日发电量、总发电量、CO2减排量等,逆变器运行状态指示,实时时间,以及其他操作菜单。下图分别是主界面的中英文显示菜单。
