摘要
电力电子装置产生的谐波已成为电力系统的主要谐波污染源。对带直流电动机负载的可控变流器进行谐波分析,得出结论:三相桥式相控整流电路相当于一个包含高次谐波的电流谐波源。提出了相应的谐波抑制策略。用Matlab/Simulink软件包建立仿真模型,给出实验结果。仿真结果表明措施是可行的。
The harmonics generated by electronic equipment become the major harmonic sources in power systems. Analyses the harmonics in current of converter circuit with DC motor. So reach the conclusion that three -phases bridge phase- control rectifier circuit is equal to a current harmonic resource with high frequency harmonics. The relevant strategies for restraining harmonics arc presented. The simulational model with the soft of MATLAB/SIMULINK was set up and simulation result was given. The simulation results show the strategies is successful.
