摘要
介绍了电力系统的谐波问题,阐述了有源电力滤波器(APF)的基本工作原理和瞬时无功功率理论,在此基础上,建立了三电平APF的数学模型,并且结合三电平SVPWM简化算法完成了APF系统实验研究,解决了APF在煤矿高电压大功率场合下的应用问题,实验结果证明了该方案具有良好的谐波补偿效果。
The article describes the power system harmonic problems,expoundes the basic working principle of active power filter(APF) and elaborated instantaneous reactive power theory,on these bases,establishes a mathematical model of the three-level APF,and completes the APF system with the three-level SVPWM simplified algorithm,solves problem of the APF application in high-voltage high-power occasion of coal mine.Experimental results show that the program has a good harmonic compensation effect.
