油田动力系统主要包括各种注水泵、输油泵、抽油机及潜油泵等的配套电动机所组成的用电负荷。据统计目前国内各大、中油田这部分负荷约占总负荷的75～80％,这些电机目前几乎全是采用感应式异步电动机,由于该种电机的自身功率因数较低,加之相当数量的生产机械暂处于轻载状态运行,所以造成油田6kV及380V网络的平均功率因数甚低,由此产生了一系统的不良后果:它使电网供电质量降低;增加了输、配电系统的网损;减少了供电设施的负荷能力;影响了网上各用电设备
Oilfield power system includes a variety of water injection pumps, oil pumps, pumping units and submersible pumps and other supporting motor composed of electricity load. According to the statistics, at present, the load of this part of China Oilfield accounts for about 75-80% of the total load. At present, almost all these motors use induction induction motors. Due to the low self-power factor and the considerable amount of production Mechanical temporarily in light load operation, resulting in the oil field 6kV and 380V network, the average power factor is very low, resulting in a system of adverse consequences: it reduces the quality of power supply network; increased transmission and distribution network losses; Reduce the load capacity of power supply facilities; affect the online power equipment
