【摘要】：逆變電源廣泛應用于人們平時的生活、工作中,隨著社會的不斷發(fā)展進步,人們對電源的質量要求也越來越高,保證逆變電源的電能質量、輸出穩(wěn)定、調節(jié)迅速正是現(xiàn)代用電設備的基本要求,也是電源廠商追求的性能指標。然而由于現(xiàn)在社會對電源容量的要求進一步提高,單臺逆變器已經無法在功率密度上滿足人們的需求,從而使得逆變器并聯(lián)技術越來越受現(xiàn)代逆變器研究者們的青睞,并將它作為一種可以實現(xiàn)大功率、高可靠性的技術手段。本文主要從逆變器波形控制和并聯(lián)運行性能進行研究,并通過單機運行、雙機并聯(lián)運行等實驗手段驗證了該課題的可行性。本文首先介紹了逆變器波形控制和并聯(lián)控制的方法策略,并通過定性分析比較了各種控制手段的優(yōu)缺點,然后針對大功率高性能逆變器技術要求,提出了一種電壓外環(huán),電流內環(huán)的雙環(huán)PID控制方式,并通過matlab建模仿真驗證了其控制方式對逆變器輸出波形的改善,有效地提高了逆變器輸出系統(tǒng)的動態(tài)性能和抗負載擾動能力。本文還通過矢量分析、功率分析闡述了雙環(huán)控制對逆變器并聯(lián)運行的影響,并在此基礎上選取了一種基于分散邏輯控制的并聯(lián)控制手段,最后本文通過在三相組合式逆變器并聯(lián)系統(tǒng)上的單機、并機的實驗有效地驗證了課題的分析假設:雙環(huán)控制能使逆變器輸出波形具有較好的動態(tài)性能和抗干擾能力,分散邏輯控制能有效地抑制并聯(lián)系統(tǒng)中的環(huán)流,并能穩(wěn)定運行。
[Abstract]:Inverter power supply is widely used in people's daily life and work. With the development and progress of society, the quality of power supply is becoming more and more high, which ensures the power quality of inverter power supply, and the output is stable. Rapid regulation is the basic requirement of modern power equipment, and also the performance index pursued by power supply manufacturers. However, due to the further improvement of power supply capacity in the society, the single inverter can not meet the needs of people in power density, which makes the inverter parallel technology more and more popular with the researchers of modern inverter. And it can be used as a high-power, high-reliability technical means. In this paper, the waveform control and parallel operation performance of the inverter are studied, and the feasibility of the subject is verified by the single machine operation and the parallel operation of the two machines. In this paper, the methods of waveform control and parallel control of inverter are introduced, and the advantages and disadvantages of various control methods are analyzed and compared qualitatively. Then, a voltage outer loop is proposed to meet the technical requirements of high power and high performance inverter. The double loop pid control method of the current inner loop is used to verify the improvement of the inverter output waveform by matlab modeling and simulation. The dynamic performance and anti-load disturbance ability of the inverter output system are improved effectively. Through vector analysis and power analysis, the influence of double loop control on the parallel operation of inverter is discussed, and a parallel control method based on decentralized logic control is selected. Finally, through the single machine on the three-phase combined inverter parallel system and the experiment of the machine, the analysis hypothesis of the subject is validated effectively: the double loop control can make the inverter output waveform have better dynamic performance and anti-jamming ability. Decentralized logic control can effectively suppress the circulation in parallel system and can operate stably.
