【摘要】：對Boost型脈寬調(diào)制(PWM)整流器的并聯(lián)環(huán)流產(chǎn)生機(jī)理進(jìn)行了詳細(xì)分析。通過在αβ0坐標(biāo)系下建模,將環(huán)流劃分為共模環(huán)流、差模環(huán)流、高頻環(huán)流3類,揭示了各類環(huán)流的影響因素。在此基礎(chǔ)上,基于比例諧振調(diào)節(jié)器,針對差模環(huán)流和共模環(huán)流分別設(shè)計了獨(dú)立控制器。由于αβ0坐標(biāo)系不需要電網(wǎng)相位信息,因此該控制策略能夠省略鎖相環(huán)節(jié),簡化計算量和控制結(jié)構(gòu)。在600kVA對拖平臺上進(jìn)行了實(shí)驗,驗證了機(jī)理分析的正確性與控制策略的有效性。
[Abstract]:The generation mechanism of parallel circulation of Boost type (PWM) rectifier with pulse width modulation is analyzed in detail. By modeling in 偽 尾 0 coordinate system, the circulation is divided into three categories: common mode circulation, differential mode circulation and high frequency circulation. On this basis, independent controllers are designed for differential mode circulation and common mode circulation based on proportional resonant regulator. Because the phase information of power network is not required in 偽 尾 0 coordinate system, the control strategy can omit the PLL node and simplify the calculation and control structure. Experiments on the towing platform by 600kVA are carried out to verify the correctness of the mechanism analysis and the effectiveness of the control strategy.
