摘要
并联型三相四线制有源电力滤波器(APF)具有良好的滤波效果,其关键是能准确地补偿谐波电流,在此问题上谐波电流检测显得至关重要。为此,提出一种基于自适应有限脉冲响应(FIR)预测与FBD电流检测相结合的电流检测算法,通过Matlab仿真证明了理论的正确性,并在一台15 kVA的样机上验证了这种新算法的可行性与有效性。
Shunt three-phase four-wire active power filter(APF) has a good filtering effect,the key is that the har-monic current can be compensated accurately and current testing is critical on this issue.Therefore,a method based on an current testing algorithm of combining adaptive finite impulse response(FIR) with FBD is proposed and Matlab simulation is done accurately.It is proves that the new algorithm is feasible and effective by the experimental results in a 15 kVA APF prototype.
