摘要
研究了现有常用的电流波形畸变检测方法,包括ip-iq法、傅里叶分解法、自适应法和FBD法等,比较了各种方法的优缺点。通过软件仿真,重点对FBD谐波电流检测法和自适应谐波电流检测法进行分析。在实验室条件下搭建有源电力滤波器系统,谐波检测算法采用FBD法,电流跟踪采用基于载波PWM控制算法,试验所得结果证明了理论的正确性和方法的可行性。
The commonly used harmonic detecting method was researched,including ip-iq method,Fourier method,adaptive method and fryze buchholz dpenbrock（FBD） method.Some simulations were made about FBD method and adaptive detecting method to illustrate characteristics of them.In the circumstance of laboratory,a test system of active power filter was built,FBD method was adopted in harmonic detecting and triangular carrier current control strategy was adopted in current tracking method.The results obtained in simulation and test platform show the rationality of the system design and correctness of algorithm.
