【摘要】:混沌理論在非線性系統(tǒng)研究中已經(jīng)占據(jù)了重要地位,在諸多領(lǐng)域都可以發(fā)現(xiàn)其卓越的研究成果和實(shí)用價(jià)值。就目前而言,電力系統(tǒng)如何能夠安全穩(wěn)定運(yùn)行,已經(jīng)成為人們?cè)絹?lái)越關(guān)注的話題,當(dāng)電力系統(tǒng)產(chǎn)生混沌振蕩現(xiàn)象的時(shí)候,就會(huì)對(duì)系統(tǒng)的穩(wěn)定運(yùn)行產(chǎn)生一定影響,甚至?xí)o整個(gè)互聯(lián)電力系統(tǒng)帶來(lái)巨大的損失。由于電力系統(tǒng)顯著的非線性特征,它會(huì)在一定條件下產(chǎn)生無(wú)規(guī)則的混沌振蕩。為了克服混沌振蕩對(duì)系統(tǒng)造成的破壞,保證系統(tǒng)正常高速的平穩(wěn)運(yùn)行,所以需要進(jìn)行深入的分析并找出切合實(shí)際的控制方法。 通過(guò)對(duì)混沌現(xiàn)象及其發(fā)展歷程的介紹,就目前混沌的研究現(xiàn)狀加以分析和解釋說(shuō)明,指出研究的目的和意義,概述研究?jī)?nèi)容及技術(shù)路線。對(duì)混沌的本質(zhì)定義和基本特性進(jìn)行了分析,并對(duì)混沌分類及判定規(guī)律做了進(jìn)一步說(shuō)明,著重介紹了當(dāng)前應(yīng)用最為廣泛的幾種混沌控制方法。針對(duì)幾種典型的電力系統(tǒng)混沌模型進(jìn)行分析研究,根據(jù)不同數(shù)學(xué)模型的不同性質(zhì)判斷其發(fā)生混沌的條件,,并研究通向混沌的路徑。介紹了滑模變結(jié)構(gòu)控制與模糊控制的相關(guān)理論和抖振問(wèn)題,選取二階互聯(lián)電力系統(tǒng)的數(shù)學(xué)模型為研究對(duì)象,采用滑模變結(jié)構(gòu)控制方法,由于傳統(tǒng)滑模變結(jié)構(gòu)控制的基本特性,所以該方法存在高頻抖振的缺點(diǎn),在控制過(guò)程中加入模糊控制規(guī)則,設(shè)計(jì)模糊滑模變結(jié)構(gòu)控制器,進(jìn)行理論數(shù)值分析并通過(guò)MATLAB仿真平臺(tái)實(shí)現(xiàn)。仿真結(jié)果表明,模糊滑模變結(jié)構(gòu)控制器既抑制了電力系統(tǒng)的混沌振蕩,又對(duì)高頻抖振起到了很好的消除作用,驗(yàn)證了設(shè)計(jì)的優(yōu)越性。
[Abstract]:Chaos theory has played an important role in the study of nonlinear systems, and its outstanding research results and practical value can be found in many fields. At present, how can power systems operate safely and stably. People have become more and more concerned about the topic, when the power system chaotic oscillation phenomenon, it will have a certain impact on the stable operation of the system. It will even bring huge losses to the whole interconnected power system, due to the remarkable nonlinear characteristics of the power system. In order to overcome the damage caused by chaotic oscillation and ensure the system running smoothly and at high speed, it can produce irregular chaotic oscillation under certain conditions. Therefore, it is necessary to carry out in-depth analysis and find out practical control methods. Through the introduction of chaos phenomenon and its development course, the present research situation of chaos is analyzed and explained, and the purpose and significance of the study are pointed out. The essential definition and basic characteristics of chaos are analyzed, and the classification and judging law of chaos are further explained. The most widely used chaos control methods are introduced in this paper. Several typical chaotic models of power system are analyzed and studied. According to the different properties of different mathematical models, the conditions of chaos are judged. The related theories and buffeting problems of sliding mode variable structure control and fuzzy control are introduced. The mathematical model of second order interconnected power system is chosen as the research object and the sliding mode variable structure control method is adopted. Because of the basic characteristics of the traditional sliding mode variable structure control, this method has the shortcoming of high frequency buffeting. Fuzzy control rules are added to the control process and fuzzy sliding mode variable structure controller is designed. The simulation results show that the fuzzy sliding mode variable structure controller can suppress the chaotic oscillation of power system. It also plays a good role in eliminating the high frequency buffeting and validates the superiority of the design.
