摘　　要：在10kV线路上装设无功补偿装置可以有效地改善电压、提高运行经济性的前提下,提出了10kV配电网高低压综合电压无功优化模型,该模型在传统的低压侧补偿、首端电压以及配变分接头调整控制的基础上融入了10kV线路补偿控制,并提出了遗传算法应用于配电网电压无功优化时的初始群体产生两步法,介绍了采用该改进的遗传算法求解该综合优化模型的处理方法和主要步骤。采用门头沟一条实际的10kV配电线路进行优化说明了将10kV侧无功补偿纳入电压无功补偿模型进行综合考虑的必要性与可行性。The installation of the 10 kV line reactive power compensation device can effectively improve the voltage and increase the operating economy. Voltage and reactive power integrated optimization algorithm in 10 kV distribution systems is proposed on this premise .The model adds 10 kV line compensation control to the traditional voltage and reactive power optimization considering low-voltage side compensations, the first terminal voltage and distribution transformer tap .This paper presents an improved genetic algorithm and introduces the approach and main steps of using this algorithm to solve the integrated optimization. Finally, a real 10 kV distribution line of Mentougou has been optimized, which shows that it is very necessary and feasible to add 10 kV line side compensation into voltage and reactive power compensation.
