发布时间：2018-08-08 20:13
【摘要】：分析了抽油机负荷叠加特性,根据油田配电网抽油机负荷功率变化特点,将某台变压器所连多台抽油机负荷曲线叠加后的不规则有功功率曲线等效为某单台抽油机负荷有功功率正弦变化的曲线,推导出抽油机负荷叠加后的油田配电网近似线损计算公式。采用该线损计算公式作为评价函数,对油田配电网进行网络重构。利用网络结构划分方法划分出油田配电网的支链邻接表,提出一种禁忌搜索算法,采用单步移动作为领域搜索策略,提高搜索精度。算例结果表明,提出的线损计算公式和禁忌搜索算法能够有效适用于油田配电网网络重构。
[Abstract]:The superposition characteristic of pumping unit load is analyzed. According to the characteristics of load power variation of pumping unit in oil distribution network, The irregular active power curve after superposing the load curves of several pumping units connected with a transformer is equivalent to the sinusoidal variation curve of the load active power of a single pumping unit. The approximate line loss calculation formula of oil field distribution network after the superposition of pumping unit load is derived. The line loss calculation formula is used as the evaluation function to reconstruct the oil field distribution network. A Tabu search algorithm is proposed by using the network structure partition method to divide the branch chain adjacent table of the oil field distribution network. The single step movement is used as the domain search strategy to improve the search accuracy. The results show that the proposed formula and Tabu search algorithm can be effectively applied to the reconfiguration of oil field distribution network.
