1、第49卷第6期Vol.49No.62013年6月HighVoltageApparatusJun.2013·93·基于DSP的調(diào)容式消弧線圈補(bǔ)償裝置的設(shè)計劉毅11121，付周興，南福東，路寧，馬誠（1.西安科技大學(xué)電氣與控制工程學(xué)院，西安710054；2.寶雞供電局，寶雞721004）摘要：筆者對自動調(diào)諧消弧線圈的發(fā)展現(xiàn)狀及存在的問題進(jìn)行了研究和分析，針對2.2kV·A/220V的調(diào)容式消弧線圈及其2kvar的電容調(diào)節(jié)柜，設(shè)計了基于TMS320F2812控制可控硅投切電容器的調(diào)容式消弧線圈，并闡明了其工作原理以及硬件和軟件設(shè)計方案。結(jié)果
2、表明，調(diào)容式自動跟蹤消弧補(bǔ)償系統(tǒng)能實現(xiàn)電容電流的在線測量，電網(wǎng)運(yùn)行狀態(tài)的自動識別和對地電容電流的完全補(bǔ)償?shù)裙δ?，達(dá)到了電網(wǎng)電容電流自動補(bǔ)償?shù)囊螅煌瑫r完成了LCD128×64顯示模塊實時參數(shù)的人機(jī)交互界面。經(jīng)試驗得出調(diào)容試消弧線圈各級補(bǔ)償電流實際值，并與理論值進(jìn)行比較且分析了誤差原因。所以，該裝置具有調(diào)諧速度快，范圍寬，可靠性高，對電網(wǎng)無諧波污染，具有良好的應(yīng)用前景。關(guān)鍵詞：消弧線圈；TMS320F2812；可控硅投切電容器；自動補(bǔ)償；液晶顯示模塊中圖分類號：TM475文獻(xiàn)標(biāo)志碼：A文章編號：1001-1609（2013）06-009
