摘要
应用MATLAB7.0中的SIMULINK仿真软件对有源电力滤波器系统进行数学建模,通过分析、比较有三相负载电流的输出波形,可检测到其线路中电流的畸变率从原来的28.87%下降至7.83%,证明本次所设计的有源电力滤波器系统能够抑制电网的谐波,说明了有源电力滤波器的谐波抑制和无功补偿的设计可以达到较好的效果,此设计具有一定的实际意义与工程实现价值.
The thesis constructs the mathematic model of APF by means of the SIMULINK block of MATLAB 7.0 and analyzes the output current wave. It shows that the APF system can effectively suppress the harmonic and the total harmonic distortion of the current has been decreased from28.87% to7.83%. The simulation results prove that the design of this system can inhibit the active power filter harmonic grid. This paper describes the design of active power filter harmonic suppression. The reactive power compensation can achieve good results, and has a certain practical meaning and value of project realization.
