【摘要】：近年來(lái),無(wú)功補(bǔ)償技術(shù)不斷發(fā)展,技術(shù)日益完善、功能越發(fā)全面,應(yīng)用覆蓋面也非常廣泛,同時(shí)無(wú)功補(bǔ)償技術(shù)更加趨于智能化,并且無(wú)功補(bǔ)償裝置的體積也越來(lái)越小。靜止同步補(bǔ)償器作為功能最為全面的無(wú)功補(bǔ)償裝置是研究的重點(diǎn)課題,STATCOM的優(yōu)點(diǎn)是調(diào)節(jié)速度更快、諧波少、體積小、調(diào)節(jié)能力強(qiáng),這些特點(diǎn)都是其他補(bǔ)償裝置無(wú)法比擬的。因此,現(xiàn)在STATCOM是國(guó)內(nèi)外研究的焦點(diǎn)。由于STATCOM屬于非線性、多元化系統(tǒng),在控制策略中時(shí)常存在耦合現(xiàn)象,導(dǎo)致控制性能不穩(wěn)定。同時(shí)STATCOM具有時(shí)變性,屬于動(dòng)態(tài)系統(tǒng),而常規(guī)PI控制參數(shù)很難整定,并且PI控制器存在動(dòng)態(tài)響應(yīng)時(shí)間長(zhǎng)、過(guò)沖大等缺點(diǎn),嚴(yán)重影響控制精度和魯棒性。針對(duì)這些問(wèn)題,本文采用瞬時(shí)功率控制,并進(jìn)行相應(yīng)的解耦,來(lái)解決耦合現(xiàn)象,提高控制性能；同時(shí)本文設(shè)計(jì)了模糊PI控制器,不但擁有模糊控制魯棒性強(qiáng)、適應(yīng)性強(qiáng)的特點(diǎn),也兼?zhèn)淞顺Ｒ?guī)PI控制簡(jiǎn)單的優(yōu)點(diǎn)。最后通過(guò)仿真和實(shí)驗(yàn)進(jìn)行分析,證明STATCOM控制系統(tǒng)的控制性能穩(wěn)定,完成了預(yù)期目標(biāo)所設(shè)定的補(bǔ)償值。同時(shí)本文介紹無(wú)功補(bǔ)償?shù)母艣r及STATCOM國(guó)內(nèi)外發(fā)展現(xiàn)狀,分析了STATCOM動(dòng)態(tài)數(shù)學(xué)模型,并對(duì)STATCOM控制系統(tǒng)及模糊控制器進(jìn)行介紹和設(shè)計(jì)。最后對(duì)實(shí)物進(jìn)行現(xiàn)場(chǎng)數(shù)據(jù)搜集并進(jìn)行分析。
[Abstract]:In recent years, the reactive power compensation technology has been developing, the technology is becoming more and more perfect, the function is more comprehensive, the application coverage is also very extensive, at the same time, the reactive power compensation technology tends to be more intelligent, and the volume of the reactive power compensation device is becoming smaller and smaller. As the most comprehensive reactive power compensation device, static synchronous compensator has the advantages of faster regulation speed, less harmonics, smaller volume and better regulating ability, which are unparalleled by other compensators. Therefore, STATCOM is the focus of research at home and abroad. Because STATCOM belongs to nonlinear and multiplex systems, there is often coupling phenomenon in control strategy, which leads to unstable control performance. At the same time, the STATCOM is time-varying and belongs to the dynamic system, but the conventional PI control parameters are difficult to adjust, and the PI controller has the shortcomings of long dynamic response time and overshoot, which seriously affect the control accuracy and robustness. To solve these problems, this paper uses instantaneous power control and decoupling to solve the coupling phenomenon and improve the control performance. At the same time, a fuzzy PI controller is designed, which not only has the characteristics of strong robustness and adaptability of fuzzy control. It also has the advantages of simple control of conventional PI. Finally, through the analysis of simulation and experiment, it is proved that the control performance of the STATCOM control system is stable and the compensation value set by the expected target is achieved. At the same time, this paper introduces the general situation of reactive power compensation and the development of STATCOM at home and abroad, analyzes the dynamic mathematical model of STATCOM, and introduces and designs the STATCOM control system and fuzzy controller. At last, the field data collection and analysis are carried out.
