摘要

为保证滤波器失谐情况下仍具有最佳的滤波效益

提出一种基于最佳偏调谐的滤波器优化设计方法。该方法选取各滤波支路补偿容量作为优化变量

考虑无功功率平衡、谐波电压、谐波电流限制等

以母线电压畸变率最小为目标函数

建立含最佳偏谐率变量的优化模型。通过迭代求解

可得到各滤波支路最佳补偿容量和最佳调谐频率

保证失谐情况下滤波器具有最佳滤波效果。对具体工程实例计算表明

与传统经验优化方法相比

该方法设计的滤波器在失谐情况下具有更佳的滤波效果。

Abstract

This paper proposes an optimal design method for passive filters based on an optimal tuned frequency

which can ensure the detuning filter still has the best efficiency.The optimization model based on the optimal tuned frequency selects the capacitance of each branch as an independent optimization variable and minimizes the total voltage harmonic distortion

considering the reactive power balance

the harmonic voltage and harmonic current limits.The optimal compensation capacity and the optimal tuned frequency can be obtained through the iterative algorithm.A study case shows that the filters designed with the proposed method has better efficiency as compared to those filters designed with experience.
