中文摘要:

为了充分利用PWM整流器的容量，实现对电网无功功率的调节及电网电压的稳定控制，本文深入分析了一种基于PWM整流器的无功补偿容量整定方法。重载情况下，PWM整流器在其容量范围内向电网不补偿或少量补偿无功功率，无功功率补偿量由PWM整流器的额定容量和直流负载功率共同决定；轻载情况下，PWM整流器能够补偿电网所缺的所有无功功率。本文还详细分析了直流电容参数的选取方法。最后通过MATLAB/simulink仿真进行了验证，仿真结果表明该整定方法能够实现无功功率的动态补偿。

英文摘要:

In order to fully employ the capacity of the PWM rectifier, realise the regulation of reactive power and the stable control of voltage in the grid, a deep analysis of a reactive power compensation capacity tuning method based on PWM rectifier has been presented in this paper. In heavy load situations, the PWM rectifier does not compensate or compensate a small amount of reactive power, reactive power compensation amount is determined by the rated capacity of the PWM rectifier and the DC load power; in light load situations, the PWM rectifier can compensate the whole reactive power in the grid. This paper also analysis the selection method of the DC capacitor parameter in detail. At last，it validates the system through the MATLAB/simulink, simulation results show that the tuning method can realise dynamic reactive power compensation.
