Abstract：Taking Ridong crude oil pipeline for example, the mathematical model of each pump unit under the peak and valley pricing system is established for optimal operation, which considers the effect of the oil flow, friction, elevation and viscosity. In the case of the guarantee of the daily oil transportation plan, the minimum pump consumptions of the average output and the output as the adjustment of the electricity price are solved, and the optimal configuration of the pumps and the oil transportation schedule are obtained. The calculation results indicate that the cost of energy consumption can be reduced for optimal operation when the daily output of the pipeline is in a certain range under the peak and valley electricity pricing system. At the same time, as the Ridong crude oil pipeline is using on-line mixing transportation technology, through the analysis and comparison of unit energy consumption of oil transportation with different mixing proportion, it is indicated that oil of different mixing viscosity is provided with different energy saving effect, which has some theoretical guiding significance for the Ridong mixed transportation line.
