【摘要】：當(dāng)今社會,隨著工業(yè)生產(chǎn)水平的發(fā)展,產(chǎn)生了很多電能質(zhì)量問題,其中,影響電能質(zhì)量最重要的兩個即為諧波污染和無功功率的消耗。電力電子作為最大的諧波源,在其運行時產(chǎn)生大量的諧波,污染電力系統(tǒng)環(huán)境,并且也會損耗無功功率,降低系統(tǒng)的功率因數(shù),影響電能質(zhì)量。面對諧波治理最主要的措施是在電源側(cè)裝設(shè)APF,而靜止無功補償器SVC是補償無功的重要裝置。本論文主要將二者綜合在一起進行研究,使其在諧波抑制的同時也能進行無功補償,極大地發(fā)揮兩個裝置的優(yōu)點,同時也能相互彌補各自的不足,有效地提高電能質(zhì)量。本論文首先對無功功率和諧波的研究現(xiàn)狀作了簡單的闡述,就此提出了 APF與SVC綜合補償方案,并對其背景作了簡要概述。接著,論文對有源電力濾波器進行闡述。隨后著重論述了諧波電流檢測技術(shù)對APF的重要性,通過對p、q和ip、iq運算方式的介紹,搭建仿真模型,通過波形圖的對比分析可得,ip、iq運算方式的結(jié)果更加精確。此外,還簡述了 APF的幾種控制方法,通過對三角波比較方式的仿真,驗證了其方法的有效性,故本論文選擇了三角波比較控制。然后,通過對靜止無功補償器SVC的介紹(本文主要選擇TCR型),論述了TCR的工作原理與連接方式,并且利用MATLAB仿真技術(shù)搭建了單相TCR與三相TCR仿真圖,通過對二者的對比分析可得,三相TCR的無功補償效果最好。最后,將有源濾波器APF與靜止無功補償器SVC綜合在一起,搭建拓撲圖,并用仿真技術(shù),搭建仿真圖,由所得到的波形圖可得APF與SVC能夠迅速得進行無功補償與諧波抑制,并且綜合方案更高效穩(wěn)定,驗證了 APF與SVC綜合補償方案的高效性。
[Abstract]:Nowadays, with the development of industrial production level, there are many power quality problems. Among them, the two most important factors affecting power quality are harmonic pollution and reactive power consumption. Power electronics is the largest harmonic source. It produces a lot of harmonics, pollutes the environment of the power system, and also loses the reactive power and reduces the power factor of the system. The most important measure for harmonic control is to install APFs on the power side, and the static Var compensator (SVC) is an important device for compensating reactive power. It can compensate reactive power while suppressing harmonics, greatly exerting the advantages of the two devices, and making up for each other's shortcomings at the same time. In this paper, the current research status of reactive power and harmonic is briefly described, and a comprehensive compensation scheme of APF and SVC is proposed, and its background is summarized briefly. In this paper, the active power filter is described, and the importance of harmonic current detection technology to APF is emphasized. The simulation model is built by introducing the operation methods of PQ and IPQ. In addition, several control methods of APF are briefly described, and the effectiveness of the method is verified by the simulation of triangular wave comparison. Therefore, this paper chooses triangle wave comparison control. Then, through the introduction of static Var compensator (SVC), the principle and connection of TCR are discussed. The simulation diagram of single-phase TCR and three-phase TCR is built by using MATLAB simulation technology. Through the comparison and analysis of the two, the reactive power compensation effect of three-phase TCR is the best. Finally, the active power filter APF is integrated with the static Var compensator SVC. Build topology diagram, and use simulation technology, build simulation diagram, from the obtained waveform diagram can be obtained APF and SVC can quickly carry out reactive power compensation and harmonic suppression, and the comprehensive scheme is more efficient and stable, The efficiency of the comprehensive compensation scheme of APF and SVC is verified.
