For solving the issue of high line loss of distribution network for oil field

in this paper

a kind of reactive power compensation method which shunts the fixed capacitor at the low voltage side of distribution network for the oil field is proposed. The load characteristics of oil pumps are analyzed. It is pointed out that the waveform of active power of the oil pump is approximately sinusoidal while the reactive power remains almost unchanged. The oil field distribution network can be compensated by the fixed capacitor in accordance the reactive power of oil pump. A kind of improvement method on the power loss analysis of the oil field distribution network with consideration periodic fluctuation of oil pump load and it is pointed that the use of conventional analysis method will lead to small of analysis result of the loss power. On this basis

the maximum reduction of power loss is taken as objective function and the improvement rate of loss reduction and total investment limit as termination condition so to set up the optimization model of shunt fixed capacitor at the low voltage side

and the optimal compensation number and position of the capacitor is solved by the use of random sampling optimization algorithm. The distribution network of two oil fieldsare taken as example for analysis and it is shown by the result that the compensation proposal of the fixed capacitor can reduce effectively the line loss of the oil filed distribution network.
