摘　　要：油田配电网处于供电系统的末端,直接面向采油设备,是保障供电可靠性与运行经济性的关键环节。油田配电系统拓扑结构复杂,设备种类繁多,线路潮流存在一定的波动性,网损率普遍高于普通配电网络。分布式光伏电源的接入,将改变油田配电网络的潮流大小以及潮流方向,由此影响网络损耗。对此研究了分布式光伏接入后的网损计算方法,结合具体油田配电网拓扑结构与设备参数,对某油田配电网进行仿真,详细分析了分布式光伏接入位置和接入容量对油田配电网网损的影响规律,为油田配电网中光伏接入及优化降损举措提供理论支撑。Oil field distribution network is at the end of the power supply system and directly serves the oil production equipment,which is the key link to ensure power supply reliability and operation economy.Oil field distribution system has a complex topology,a wide equipment diversification,and a certain extent of volatility in line currents,so the network loss rate is generally higher than in ordinary distribution networks.The integration of distributed photovoltaic power sources will change the size and direction of the tidal current in the oilfield distribution network,thereby affecting the network loss.Research on the calculation method of network loss with distributed photovoltaic has been introduced in this paper.By combining the topological structure with equipment parameters of specific oil field distribution network,the actual network structure of an oil field distribution network is simulated,and the influence of distributed photovoltaic access location and access capacity on network loss is analyzed.This work is expected to provide theoretical support for photovoltaic access and loss reduction measures of oilfield distribution network.
