| 摘 要： | 为设计静止无功发生器的直流侧电压,分析了直流侧电压的取值对补偿特性的影响,提出了直流侧电压的设计方法.该方法通过输出的无功电流设计完全补偿无功功率时所需的直流侧电压理论最小值,当直流侧电压小于理论最小值时,在正弦调制方法和非正弦调制方法下,分别通过功率因数和谐波电流设计直流侧电压,并且定量分析了在非正弦调制方法下保证电源基波功率因数为1时注入电网的谐波电流值.与工程应用中通过工程经验或者通过仿真来设计直流侧电压的方法相比,该方法可以定量地设计直流侧电压,减小了直流侧电压设计的盲目性.实验验证了所提出的设计方法的有效性.

| Abstract: | The design scheme of DC side voltage in Static Var Generator (SVG) is presented in a quantitative manner. The extensive analysis of the influence of DC side voltage on the performance of SVG is carried out,and a specification of the DC side voltage rated value is presented. A required lowest value of DC side voltage for full compensation (a unity total power factor) is obtained according to the output reactive current. For the situation of DC voltage is smaller than the above-obtained lowest value,the DC si... |
