摘要

将配电系统中的谐波滤波器规划作为一个组合优化问题，采用微遗传算法求解。考虑了分布线性和非线性载荷下径向系统滤波器尺寸和定位的优化问题。以电压总谐波失真和有功功率损耗最小为目标函数。系统的谐波电平采用电流注入法计算，负荷潮流采用功率和迭代法求解，适合此类研究的精度要求。结果表明，该方法可使总电压谐波失真和有功功率损耗同时最小化。对一个15总线径向系统的仿真结果表明，该方法可以有效地解决所提出的问题。

Harmonic passive filter planning in radial distribution systems using microgenetic algorithms

The harmonic filter planning in distribution systems is presented as a combinatorial optimization problem, which is solved using microgenetic algorithms. The optimization of filter sizes and localizations on radial system with distributed linear and nonlinear loads has been considered. The minimization of voltage total harmonic distortion and active power losses has been used as an objective function. The harmonic levels of system are obtained by current injections method and the load flow is solved by the iterative method of power sum, which is suitable for the accuracy requirements of this type of study. It is shown that total voltage harmonic distortion and active power losses are minimized simultaneously. The simulation results for a 15 bus radial system show that the proposed method is efficient for solving the presented problem.
