油田配电网损耗影响因素仿真分析

Loss Influence Factor Simulation Analysis of Oil Field Distribution Network

油田配电网大多呈辐射状且分支较多,拓扑结构复杂,而且采油设备运行具有周期往复运行的特点,线路潮流存在一定的波动性,导致网损率普遍高于公用配电网。本文结合具体油田配电网拓扑结构与设备参数,并考虑油田负荷运行特点,系统分析了功率因数、电压等级、线路老化、变压器型号等因素对于网络损耗的影响机理;结合实际情况,基于Matlab建模仿真对比分析了针对不同影响因素的降损措施节能空间。为准确掌握油田配电网的网损影响主控因素并实施科学有效的降损措施,提供了理论支撑。

Oil field distribution networks are mostly radial with many branches and the topological structure is much complex.Meanwhile,the oilfield load usually works with cycling characteristics and power flow in the distribution network is with high fluctuation.The network loss rate is generally higher than that of public distribution network.In this paper,combined with the specific oil field distribution network topology and equipment parameters,and the characteristics of oilfield load operation,influence mechanism of some factors is systematically analyzed.The influence elements on the network loss are considered with the actual field situation,such as power factor,voltage level,line aging,transformer model,etc.Based on Matlab modeling and simulation,the energy-saving space of loss reduction measures for different influencing factors is compared and analyzed.It provides theoretical support for accurately grasping the main control factors of the oil field distribution network loss and implementing scientific and effective loss reduction measures.
