Reactive power compensation work of rural power grid is playing an important role on improve voltage quality and decrease of line loss, and which is related to rural power grid's economic, safety and reliable operation. As the growth of rural power load, a part of 10 kV rural power distribution line could not satisfy consumers' need because of big power supply radius, low power factor, big line loss, so the reactive power compensation potential is needed. This paper mainly expounds the significance and methods of the power grid for reactive power compensation planning, the configuration of parallel capacitor device, the methods and characteristics of the reactive power compensation and the integration efficiency analyses. Based on 10kV rural power grid of Zhouzhi shaanxi, we carried on an research and exploration by calculated the reactive power compensation method and capacity, determine the installation location, analysis the efficiency, which could provide the reference for modify the rural power grid and improve the quality and benefit of power supply of enterprises.%农网无功补偿工作对于改善电压质量、降低线损起着重要作用，关系到农村电网的经济、安全、可靠运行。随着农村用电负荷的增长，部分供电半径大、功率因数低、线路损耗大的10kV农网配电线路无法满足用户需求，必须要进行无功补偿势。针对上述情况本文主要阐述了电网制定无功补偿规划的意义和方法；并联电容器装置的配置情况；无功补偿的方式及其特点和综合效益分析。以陕西省周至县10kV农网为例对无功补偿方式及容量计算、安装位置确定和效益分析进行了研究与探索，为农网改造和提升供电企业的供电质量与效益提供参考。
