【摘要】：隨著電力電子技術(shù)的迅速發(fā)展，大量新型電力電子設(shè)備得到了廣泛應(yīng)用，這些非線性負(fù)載消耗大量無(wú)功能量的同時(shí)向電網(wǎng)注入大量諧波電流，諧波治理問(wèn)題已經(jīng)受到廣泛關(guān)注。因此，，治理電力諧波的手段與方法已成為當(dāng)今電氣工程領(lǐng)域中的重要研究課題。 單周控制（OCC）是一種新型大信號(hào)非線性控制技術(shù)，其系統(tǒng)具有可靠性高、控制精度好、動(dòng)態(tài)跟蹤響應(yīng)快等優(yōu)點(diǎn)，并已在眾多領(lǐng)域中被廣泛采納。本文就單周控制在有源濾波器控制中的應(yīng)用進(jìn)行了研究和仿真分析。 本文首先詳細(xì)介紹了單周控制理論的概念和基本原理，建立了基于單周控制的APF功率級(jí)模型，并對(duì)其進(jìn)行理論推導(dǎo)，總結(jié)出模型各變量之間的關(guān)系。對(duì)單周控制單相APF控制方程進(jìn)行推導(dǎo)，根據(jù)電路實(shí)際工作情況，引出重要中間量Vm，并分析其調(diào)整過(guò)程和各主要器件參數(shù)值的選取方法和準(zhǔn)則；整定了PI調(diào)節(jié)器中P、I環(huán)節(jié)的物理意義及應(yīng)滿足的條件，對(duì)控制器參數(shù)選擇具有指導(dǎo)作用。 本文對(duì)基于單周控制技術(shù)的單相APF的仿真電路進(jìn)行設(shè)計(jì)，通過(guò)采用PSIM6.0仿真軟件進(jìn)行濾波仿真，證明了這種控制方式在單相APF應(yīng)用的正確性和可行性。 在單周控制單相APF研究的基礎(chǔ)上，推導(dǎo)出單周控制三相APF的控制方程，根據(jù)方程式的形式設(shè)計(jì)出相應(yīng)的仿真電路。最后采用PSIM6.0軟件進(jìn)行濾波仿真，證明了上述分析的正確性和可行性。
[Abstract]:With the rapid development of power electronics technology, a large number of new power electronic devices have been widely used. These nonlinear loads consume a lot of reactive energy and inject a large number of harmonic currents into the power network at the same time. The problem of harmonic control has been paid more and more attention. Therefore, the means and methods of harmonic control have become an important research topic in the field of electrical engineering. Occc is a new type of large signal nonlinear control technology. Its system has the advantages of high reliability, good control precision, fast dynamic tracking response and so on. It has been widely adopted in many fields. In this paper, the application of one-cycle control in APF control is studied and simulated. In this paper, the concept and basic principle of one-cycle control theory are introduced in detail, and the APF power level model based on one-cycle control is established, and its theoretical derivation is given. The relationship between each variable of the model is summarized. The single-phase APF control equation of one-cycle control is deduced. According to the actual working conditions of the circuit, the important intermediate value Vm is derived, and the adjustment process and the selection method and criterion of the main device parameters are analyzed. The physical meaning and the conditions to be satisfied of the PSI link in the Pi regulator are set up, which can guide the selection of the controller parameters. In this paper, the simulation circuit of single-phase APF based on one-cycle control technology is designed, and the correctness and feasibility of this control method in single-phase APF are proved by using PSIM6.0 simulation software. On the basis of single-phase APF research of one-cycle control, the control equation of one-cycle control three-phase APF is deduced, and the corresponding simulation circuit is designed according to the form of equation. Finally, the filter simulation is carried out by PSIM6.0 software. The correctness and feasibility of the above analysis are proved.
