1 引言
隨著全球經(jīng)濟(jì)的迅猛發(fā)展,各行業(yè)能耗加劇,石油、煤炭等傳統(tǒng)化石能源日趨枯竭。世界各國都把目光投向了可再生能源,希望可再生能源改變?nèi)祟惖哪茉唇Y(jié)構(gòu),維持長遠(yuǎn)的可持續(xù)發(fā)展。在可再生能源中,太陽能以其獨(dú)有的優(yōu)勢而成為人們關(guān)注的焦點(diǎn)。太陽能是取之不盡、用之不竭、無污染的綠色能源。世界各國都在投入巨資建設(shè)大規(guī)模的太陽能發(fā)電站。我國在光伏研究和產(chǎn)業(yè)方面也取得了較快的進(jìn)展,2006年1月1日實(shí)施的《可再生能源法》,標(biāo)志著太陽能發(fā)電已納入我國的能源發(fā)展規(guī)劃之中。根據(jù)2007年9月發(fā)布的《可再生能源中長期發(fā)展規(guī)劃》,2020年,我國太陽能發(fā)電設(shè)備累計(jì)裝機(jī)容量將達(dá)到2000MW 。
太陽能光伏并網(wǎng)逆變器是整個(gè)光伏發(fā)電系統(tǒng)中最為關(guān)鍵的設(shè)備之一,它是把太陽能電池板產(chǎn)生的直流電能轉(zhuǎn)換為交流電能的設(shè)備,運(yùn)行過程中需要多個(gè)參數(shù)進(jìn)行監(jiān)測、計(jì)算、顯示、記錄、保存、報(bào)警等處理,需要和上位計(jì)算機(jī)、逆變控制器、無線GPRS模塊進(jìn)行通訊,實(shí)現(xiàn)數(shù)據(jù)交換。本文主要講述WEINVIEW觸摸屏在太陽能光伏并網(wǎng)逆變器中的應(yīng)用。
2 系統(tǒng)原理和方案設(shè)計(jì)
太陽能光伏并網(wǎng)逆變器是把太陽能電池板通過光伏效應(yīng)產(chǎn)生的直流電能進(jìn)行逆變,轉(zhuǎn)換成同電網(wǎng)同頻率、同相位的交流電,接入電網(wǎng)對外進(jìn)行輸電。逆變器運(yùn)行中要把測量的實(shí)時(shí)參數(shù)送給觸摸屏,進(jìn)行顯示、記錄等操作,也可和上位機(jī)通訊進(jìn)行遠(yuǎn)程監(jiān)控功能。系統(tǒng)結(jié)構(gòu)圖如下圖所示:

3 WEINVIEW畫面設(shè)計(jì)要求
本系統(tǒng)采用WEINVIEW MT8100I型號觸摸屏,高品質(zhì)10寸寬屏設(shè)計(jì),LED背光模組;采用400MHz RISC CPU,使運(yùn)行速度更快;內(nèi)置電源隔離保護(hù)器,提高了產(chǎn)品的抗干擾能力,適應(yīng)復(fù)雜環(huán)境下運(yùn)行;多種標(biāo)準(zhǔn)的通訊接口和網(wǎng)絡(luò)協(xié)議,方便用戶使用;大容量的數(shù)據(jù)存儲功能,并且可以直接存儲或備份到U盤、SD卡或上位機(jī)上,滿足逆變器運(yùn)行過程中產(chǎn)生的海量數(shù)據(jù)信息。
3.1 觸摸屏主界面設(shè)計(jì)
主界面顯示逆變器運(yùn)行的各種運(yùn)行參數(shù):PV電壓、PV電流、A、B、C三項(xiàng)交流電壓和電流、功率因數(shù)、電網(wǎng)頻率、輸出功率、日發(fā)電量、總發(fā)電量、CO2減排量等,逆變器運(yùn)行狀態(tài)指示,實(shí)時(shí)時(shí)間,以及其他操作菜單。下圖分別是主界面的中英文顯示菜單。
