摘要
在配电网中装设有源滤波装置是抑制谐波有效的方法。文章运用改进型的遗传算法对有源滤波装置在配电网中的配置进行优化,提出最优个体保留与最大遗传代数相结合的终止进化准则,即必须经过一定的迭代次数,最优解经过后面的多次迭代后仍为最优。最后通过一经典算例验证,改进型遗传算法既满足了抑制谐波的要求,又将投资费用控制在尽量小,应用于配电网有源装置优化配置具有可行性。
To install active power filters is an effective method to suppress harmonic in the distribu- tion system. An improved genetic algorithm was employed to optimize the active power filters config- uration in the distribution network. A criteria for terminating evolution that maintains the optimal one after the highest genetic generations was proposed. The optimal solution was proved after multi-gen- erations. The optimal solution was confirmed via a typical example. The results indicate that the im- proved genetic algorithm can suppress harmonic while reducing investment costs and is applicable in achieving optimized configuration of the active filters in the distribution system.
