    摘要:

    随着油田敏感负荷的大量使用,电压暂降问题日益突出;近年来,油田配电网推进信息化建设,为实现电压暂降源区段定位提供了数据支撑。文中基于干线式配电网结构特点与负荷矩模型,以负荷矩近似相等为出发点,建立电压监测值与线路电气距离之间的约束关系,构建了适用于干线式网络负荷分布特征的信息监测点确定方法,并通过距离系数与电压损失之间的线性关系表征线路的稳态电压分布情况,利用电压增量与监测点间电气距离之间的关系进行电压暂降源区段定位。仿真结果证明了该方法的有效性。

    Abstract:

    With the large-scale use of sensitive loads in oil fields, the voltage sag problem has become increasingly prominent. In recent years, oilfield distribution networks have promoted information construction, providing data support for the realization of voltage sag source segmentation. Based on the structural characteristics and load moment model of the mainline distribution network, the constraint relationship between the voltage monitoring value and the electrical distance of the line is established based on the similarity of the load moments. The information monitoring point suitable for the distribution characteristics of the mainline network load is constructed. Determine the method, and characterize the steady-state voltage distribution of the line by the linear relationship between the distance coefficient and the voltage loss, and use the relationship between the voltage increment and the electrical distance between the monitoring points to locate the voltage sag source segment. Simulation results demonstrate the effectiveness of the proposed method.
