Reconfiguration of the oil-field distribution network considering time-varying oil pumping loads

The load characteristic of oil pumping unit has been analyzed in this paper. According to the variation feature of power to time in oilfield distribution network that active power may vary as sine curve and reactive power may be a constant, different pumping units that connected in the same transformer equal to an equivalent single pumping unit. The approximate power loss equation of oilfield distribution network is calculated. Take this equation as an evaluating formula to reconfigure oilfield distribution network. Take advantage of the existed structure dividing method to separate the network and form adjacency list. Consider that the rapid adaption of topology cannot reach high accurate results, a Tabu Search algorithm has been proposed. This method takes single step as its neighbor search strategy thus enhanced the accuracy of results. The example shows that the proposed power loss equation and the Tabu Search algorithm are effective to the reconfiguration of oilfield distribution network.
