【摘要】：近些年交流調(diào)速系統(tǒng)得到了迅速的發(fā)展,交流變頻調(diào)速系統(tǒng)憑借著容量大、結(jié)構(gòu)簡(jiǎn)單、節(jié)能等優(yōu)點(diǎn),已經(jīng)開始漸漸取代直流調(diào)速系統(tǒng)的地位。在煤礦開采的過程中,煤礦的挖掘、運(yùn)輸?shù)榷夹枰涣髡{(diào)速系統(tǒng)。交流調(diào)速系統(tǒng)主要由變頻器和電動(dòng)機(jī)組成,現(xiàn)在大多采用把變頻器與電動(dòng)機(jī)分成兩個(gè)獨(dú)立的系統(tǒng),然后用長(zhǎng)電纜進(jìn)行連接的方式。由于井下的空間有限,生產(chǎn)環(huán)境惡劣,這樣的交流調(diào)速系統(tǒng)不僅會(huì)占更大的空間,還可能會(huì)使電能在傳輸過程中發(fā)生行波反射、噪聲干擾等使得電動(dòng)機(jī)的輸入端電壓發(fā)生變化,甚至達(dá)到額定電壓的幾倍,對(duì)電動(dòng)機(jī)的安全穩(wěn)定運(yùn)行造成不利的影響。所以隔爆型變頻調(diào)速一體機(jī)把變頻器和電動(dòng)機(jī)封裝在一起,使其體積變小,重量減輕,也降低了故障率,減小電磁干擾,更適合完成井下作業(yè)。但是變頻器電源本身自帶的諧波分量卻對(duì)電動(dòng)機(jī)產(chǎn)生了加速絕緣老化,降低電動(dòng)機(jī)效率,使電動(dòng)機(jī)的損耗增加等負(fù)面影響。目前工程上采用了LC無源濾波器對(duì)變頻器輸出的電能進(jìn)行濾波。無源濾波器的結(jié)構(gòu)簡(jiǎn)單,便于維護(hù),成本較低。但是LC無源濾波器存在只能濾除特定諧波的弊端。所以近些年也開始了在變頻器的輸出側(cè)使用有源濾波器的研究。有源濾波器能夠動(dòng)態(tài)的濾波各次諧波,濾波效果好,性能優(yōu)越。但是有源濾波器難以對(duì)大容量負(fù)載進(jìn)行諧波補(bǔ)償,成本也比較高。所以本文提出使用綜合了無源濾波器與有源濾波器的優(yōu)點(diǎn)的混合型有源濾波器來對(duì)變頻器輸出側(cè)進(jìn)行濾波。本文以撫順煤礦電機(jī)有限責(zé)任公司最新研制的產(chǎn)品隔爆型變頻調(diào)速一體機(jī)為背景,采用MATLAB/Simulink軟件仿真的方式研究了使用無源濾波器與有源濾波器相結(jié)合的混合型有源濾波器對(duì)變頻器電源諧波的抑制作用。介紹了交流調(diào)速系統(tǒng)的優(yōu)勢(shì)和現(xiàn)狀,詳細(xì)介紹了隔爆型變頻調(diào)速一體機(jī),分析了變頻器電源諧波的產(chǎn)生以及在電動(dòng)機(jī)中產(chǎn)生的附加損耗和諧波對(duì)電動(dòng)機(jī)的負(fù)面影響,介紹了各種有源濾波器與無源濾波器,分析了由有源濾波器與無源濾波器綜合而成的混合型有源濾波器的優(yōu)點(diǎn)。通過MATLAB/Simulink軟件搭建了由380V工頻電源供電的變頻器,由整流變壓器、整流電路、升壓斬波電路、濾波電路和逆變電路構(gòu)成,并且對(duì)每一部分電路進(jìn)行了驗(yàn)證。用隔爆型變頻調(diào)速一體機(jī)的實(shí)際參數(shù)設(shè)置系統(tǒng)模塊并進(jìn)行仿真。分析仿真結(jié)果并設(shè)計(jì)了相應(yīng)的濾波器。最后通過仿真驗(yàn)證了由有源濾波器與無源濾波器綜合而成的混合型有源濾波器能夠有效的削弱變頻器電源諧波,對(duì)電動(dòng)機(jī)有很好的保護(hù)作用。
[Abstract]:In recent years, AC speed regulation system has been developing rapidly. With the advantages of large capacity, simple structure and energy saving, AC frequency conversion system has gradually taken the place of DC speed regulation system. The mining and transportation of coal mines all need AC speed regulation system. The AC speed regulation system is mainly composed of frequency converter and motor. Now most of them are divided into two independent systems. Because of the limited underground space and the harsh production environment, such AC speed regulation systems not only occupy more space, but also may cause traveling wave reflection in the transmission of electric energy. Noise interference makes the input voltage of the motor change even several times the rated voltage. It has an adverse effect on the safe and stable operation of the motor. Therefore, the flameproof inverter and the motor are encapsulated together, which makes it smaller in volume and lighter in weight, and also reduces the failure rate and electromagnetic interference. It is more suitable for underground operation. However, the harmonic component of inverter power supply itself has accelerated insulation aging and reduced motor efficiency. At present, the LC passive filter is used to filter the electric energy output from the inverter. The structure of the passive filter is simple and easy to maintain. The cost is low. But the LC passive filter has the disadvantage that it can only filter the specific harmonics. So in recent years, the study of using active filter on the output side of frequency converter has been started. Active filter can filter every harmonic dynamically. The filtering effect is good, the performance is superior, but the active power filter is difficult to compensate the harmonics of the large capacity load. Therefore, this paper proposes a hybrid active power filter which combines the advantages of passive filter and active power filter to filter the output side of inverter. In this paper, Fushun Coal Mine Motor Co., Ltd. The newly developed flame-proof variable-frequency speed governing integrator is the background. In this paper, the effect of hybrid active power filter (APF) combined with passive filter and active filter on harmonic suppression of inverter power supply is studied by means of MATLAB/Simulink software simulation. The advantages and present situation of AC speed regulating system are introduced. This paper introduces the flame-proof variable-frequency speed governing integrator in detail, analyzes the harmonic generation of inverter power supply, the additional loss and the negative influence of harmonic produced in the motor, and introduces various active filters and passive filters. This paper analyzes the advantages of hybrid active power filter which is composed of active power filter and passive filter. The inverter powered by 380V power frequency power supply, rectifier transformer, rectifier circuit and boost chopper circuit are built by MATLAB/Simulink software. Filter circuit and inverter circuit, Each part of the circuit is verified. The system module is set up and simulated with the actual parameters of the flameproof frequency conversion speed governing integrator. The simulation results are analyzed and the corresponding filter is designed. Finally, the simulation results are verified by the simulation. The hybrid active power filter, which is integrated with the passive filter and the active filter, can effectively weaken the harmonic of the inverter power supply. It has a good protective effect on the motor.
