并聯(lián)混合型有源濾波器的研究
[Abstract]:With the continuous expansion of power system scale and the extensive application of a large number of nonlinear power electronic devices, the power network is subjected to more and more serious "harmonic pollution", so it is urgent to treat harmonics. The hybrid active power filter (Hybrid Power Filter,HAPF), which combines passive filter and active power filter, can reduce the investment cost of harmonic compensation system and improve the performance / price ratio of the compensation system. In order to achieve a better purpose of harmonic suppression. Therefore, the study of hybrid active power filter system has important practical significance. Based on the analysis and comparison of the advantages and disadvantages of various filters, this paper proposes a parallel hybrid active power filter (HAPF) for harmonic compensation, and designs the passive filter. Secondly, in order to solve the delay problem caused by the traditional IP-iac harmonic current detection algorithm based on instantaneous reactive power theory, this paper proposes a new IP-IQ algorithm based on the traditional algorithm By increasing the compensation angle, the algorithm compensates the delay generated by the detection process to a certain extent, and compares the two algorithms with the MATLAB simulation software. The results show that the new algorithm eliminates the delay generated by the detection process and has a better compensation effect. Thirdly, after analyzing and comparing various current tracking control methods, hysteresis comparison control method is used in this paper. Finally, the filter effect of only active power filter and shunt hybrid active power filter is simulated and analyzed. The results show that shunt hybrid active power filter can compensate harmonics in real time. The current waveform of the whole system is sinusoidal, and the harmonic compensation effect is remarkable. Therefore, the parallel hybrid active power filter (HAPF) used in this paper is an effective and feasible compensation device for power system harmonics.
