1、摘要摘要近年來，隨著工業(yè)的不斷發(fā)展，各式各樣的電器應(yīng)運(yùn)而生。電能的優(yōu)勢(shì)愈加明顯，作用也越來越重要，是現(xiàn)階段不可替代的二次能源。然而，無論是在發(fā)電、輸電、配電、用電等各個(gè)過程中，電能都是以交流的形式輸送的，無功功率的平衡就成為了一個(gè)必須解決的問題。本文所述的飽和電抗器就是其中一種無功補(bǔ)償裝置，其結(jié)構(gòu)相對(duì)簡(jiǎn)單、損耗和諧波的影響都很小，在無功補(bǔ)償方面發(fā)揮著重要作用。論文主要內(nèi)容首先以緒論的形式對(duì)飽和電抗器課題的相關(guān)背景做了介紹。通過回顧飽和電抗器的發(fā)展?fàn)顩r更加體現(xiàn)出飽和電抗器作為無功功率補(bǔ)償裝置的優(yōu)勢(shì)和進(jìn)行飽和電抗器研究的意義。通過對(duì)不同種類的飽和電抗器的性能優(yōu)勢(shì)
2、的比較，使其設(shè)計(jì)更加優(yōu)化、成本更低，從而更好地滿足實(shí)際應(yīng)用中的需要。然后對(duì)飽和電抗器的基本原理做出詳細(xì)的說明，通過各種有缺點(diǎn)的比較確定了飽和電抗器的實(shí)際結(jié)構(gòu)。確定結(jié)構(gòu)后，進(jìn)而對(duì)飽和電抗器建立數(shù)學(xué)模型，畫出等效電路圖。最后根據(jù)數(shù)學(xué)模型和基本原理的分析進(jìn)行相關(guān)的參數(shù)計(jì)算。使用MATLAB仿真軟件對(duì)整個(gè)無功功率補(bǔ)償系統(tǒng)進(jìn)行了仿真，通過對(duì)輸出波形和相關(guān)參數(shù)的分析，對(duì)前面的數(shù)學(xué)模型的建立以及電路分析做出總結(jié)。設(shè)計(jì)出了相關(guān)的控制電路，選用DSP處理器作為控制電路的核心，并設(shè)計(jì)出組成控制系統(tǒng)所需要的各個(gè)單元電路。關(guān)鍵詞：飽和電抗器，無功補(bǔ)償，磁控調(diào)壓式，MATLAB仿真-
