【摘要】:針對(duì)同步旋轉(zhuǎn)坐標(biāo)系下的三相四線制LCL并聯(lián)型有源電力濾波器控制技術(shù)的缺點(diǎn),提出一種采用PR準(zhǔn)比例諧振調(diào)節(jié)器的三相四線制LCL并聯(lián)型有源電力濾波器的控制技術(shù).該控制策略采用PR準(zhǔn)比例諧振調(diào)節(jié)器控制三相四線制LCL并聯(lián)型有源電力濾波器的電流輸出,使三相補(bǔ)償電流輸出實(shí)時(shí)跟蹤船舶上負(fù)載引起的諧波電流.針對(duì)PR準(zhǔn)比例諧振調(diào)節(jié)器在諧振頻率處有限增益導(dǎo)致的靜差問題,定性地分析各個(gè)參數(shù)對(duì)三相補(bǔ)償電流輸出的控制精度與動(dòng)態(tài)性能的影響并進(jìn)行了MATLAB仿真實(shí)驗(yàn).結(jié)果表明:采用三相四線制LCL并聯(lián)型有源電力濾波器PR準(zhǔn)比例諧振調(diào)節(jié)其控制,能夠?qū)崿F(xiàn)高精度電流補(bǔ)償.
[Abstract]:For three-phase synchronous rotation coordinates LCL four wire shunt active power filter control technology shortcomings, proposed a control technique for a three-phase PR using the quasi proportional resonant regulator LCL four wire shunt active power filter. The output current control strategy based on PR quasi proportional resonant regulator to control the three-phase four wire system the LCL shunt active power filter, the harmonic current tracking ship three-phase compensation current output load caused by PR. According to the quasi proportional resonant regulator at the resonant frequency of the resulting finite gain problem of static error, the qualitative analysis of each parameter control precision and dynamic performance of the three-phase compensation current output effect and the the MATLAB simulation experiments. The results show that the three-phase four wire shunt active power filters LCL PR quasi proportional resonant control regulation, can achieve high precision current compensation.
