摘要/Abstract

摘要： 随着局域配电网中非线性负载的分布式接入，以谐波就地补偿为目标的并联型有源电力滤波器（shunt active power filter, SAPF）传统配置方式需要接入大量治理设备，存在治理效率低、成本高问题。因此，出现了面向局域配电网谐波全局综合抑制的SAPF优化配置问题。首先利用诺顿等效法建立局域配电网谐波电压优化补偿目标函数；其次，结合非线性规划原理和几何辅助分析法对优化问题进行求解，确定SAPF在系统中的安装位置和最优配置容量，提出一种基于SAPF的电网谐波电压优化综合抑制算法；最后，通过搭建IEEE-18节点仿真模型，对所提出的算法进行验证。在网络非线性负载的不同分布情况下，配置结果都具有良好的治理效果，可通过更少数量、容量的SAPF实现配电网整体谐波畸变的高效抑制。

Abstract: With the decentralized access of non-linear loads in the local distributed network, the traditional shunt active power filter (SAPF) configuration method with the objective of local compensation of harmonics requires integration of a large number of control equipment, which leads to both low control efficiency and high control cost. Therefore, the optimization of SAPF configuration is needed for global comprehensive suppression of harmonics in the local distributed network. Firstly, the Norton equivalent method is used to establish an objective function for optimal compensation of the harmonic voltage in local distributed network. Secondly, the optimization problem is solved using the non-linear programming principle and the geometric aided analysis method to determine the installation position and optimal configuration capacity of SAPF in the system, and a comprehensive suppression algorithm is proposed for harmonic voltage in the power network based on SAPF. Finally, a simulation model of an IEEE-18 node system is established to verify the feasibility of the proposed algorithm. The results show that in the case of different distribution of nonlinear loads, all the configuration results have good control effects, and the overall harmonic distortion of the distributed network can be effectively suppressed through fewer SAPFs with less capacities.

Key words: shunt active power filter (SAPF), harmonics, local power network, aided geometric method, harmonic suppression
