摘　　要：为了有效地推进农网改造工程,在建立基波潮流、谐波潮流、无功功率补偿和农网规划数学模型的基础上,提出了一种改进型遗传算法的农网运行优化方案,即采用遗传算法寻优与灵敏度信息指导相结合之法,编制出农网基波及谐波潮流、无功补偿和优化运行软件程序包。结果表明,在线可观测基波、谐波潮流和无功补偿等状况,优化后比优化前电流谐波总畸变率平均下降了1.66%,3、5、7次谐波放大水平平均降低了约1.2%,农网年运行费用节省了13.2%。To promote the rural power network renovation engineering effectively, an optimal operation scheme of rural power network using modified Genetic Algorithm is proposed on the basis of setting up mathematics models such as fundamental load flow, harmonic component current, reactive power compensation and optimal planning of a rural power network in this paper. The related software program packages are drawn up through combining optimal solution method of genetic algorithm with sensibility information. The results indicate that the fundamental load flow, harmonic current and reactive power compensation can be observed on line, the total harmonic distortion rate of current has averagely dropped by 1.66 percent and the amplification levels of 3, 5, 7 order harmonics have also nearly dropped by 1.2 percent after optimizing the rural power network, and operation expense for the rural power network can be saved by 13.2%.
