| Sumario: | This work is devoted to intensification of the power efficiency of computerized systems of con-trol by the pumping units group of oil pumping stations of the main lines. The criterion of the energy efficiency is a minimum total energy loss. The goal set can be reached by the develop-ment of algorithms of the energy efficient control. The most important scientific result based on the identification of the mathematical models of the objects controlled is the efficient algorithm for controlling the group of oil pumping units. It allows determining in real time the operation modes of separate pumping units, upon which the total energy losses will be minimal. The sig-nificance of the results obtained consists in the energy losses decrease across the main oil pipe-line during the combined control by the pumping units groups. Their practical significance con-sists in decreasing the cost of oil transportation at the expense of decreasing the energy con-sumed by the pumping units. The main stages of plotting the modes maps were presented of the efficient operation of the pumping units based on the definition of the necessary rotation fre-quencies and positions of the regulating valves. Experimentally was performed the analysis of the operation modes of the pumping unit using different methods for productivity regulation, and their comparative energy efficiency was shown. The experimental data extrapolation was carried out, and, on its basis, the possible economic effect was determined brought by the use of the energy-conserving systems of the controlling the group of pumping systems. |
