摘要
提出了一种快速自适应谐波检测算法和三角载波电流控制相结合的方法,以基波电流作为控制参考,运用于三相三线制有源电力滤波器中。仿真结果表明该方案在电网电流存在畸变的情况下,能很好地自适应跟踪谐波,并且具有很好的动态响应和较高的检测精度等优点。
A three-phase three-wire active power filter based on combining a rapid adaptive harmonic detection with triangular carrier current control, by using the first harmonic of the current as the reference control, is presented. The simulation results show that while the current of power network distorts, this program can have a good adaptive tracking harmonic, and has a good dynamic response and higher detection accuracy advantages.
