Abstract

DC side voltage is a very important parameter in the design of parallel active power filter (PAPF), but so far, very little discussion was conducted on it in a quantitative manner by previous publications. In this paper, an extensive analysis on the DC side voltage to the performance of PAPF with SVM control is made, and a specification of the DC side voltage rated values with different compensation results is presented. Two situations are analyzed. For first situation, through equivalent circuit analysis and Fourier Transform analytical expressions, a required minimal value of DC side voltage for full compensation is obtained for six-pulse converter harmonic current. For the situation, of which the DC side voltage is smaller than the above-obtained minimal value, the quantitative relationship between the DC side voltage and the total harmonic distortion after compensation is also elaborated in the paper by using the diagram of curve. Based on these analyses, the specification of DC side voltage rated value for PAPF with SVM control is quite straight forward.

基于补偿特性的支持向量机控制并联有源电力滤波器直流侧电压分析与规范

直流侧电压是并联有源电力滤波器设计中一个非常重要的参数，但迄今为止，文献中对直流侧电压的定量讨论甚少。本文广泛分析了直流侧电压对支持向量机控制PAPF性能的影响，给出了不同补偿结果下的直流侧电压额定值规范。分析了两种情况。对于第一种情况，通过等效电路分析和傅里叶变换解析表达式，得到了六脉冲变换器谐波电流完全补偿所需的直流侧电压最小值。对于直流侧电压小于上述最小值的情况，本文还利用曲线图阐述了补偿后直流侧电压与总谐波畸变的定量关系。基于这些分析，支持向量机控制的PAPF直流侧电压额定值的规定是相当直接的。
