Algorithm to determine the rotational speed of the main pumps. Oil and Gas Business: electronic scientific journal

摘要

The article considers the problems of regulation modes of pumping oil through main pipelines switching the number of the pumps. Explain the rationale for the use of variable frequency drives to regulate the performance of the pipeline.Specified technological section of the pipeline recorded balance equation pressures for frequency regulation main pumps, taking into account regulated pumps.In the article speed of the main pumps with the modes and speeds of other pumps of technological area are discussed. The generalized expressions for the speed pumps that are valid for any number of variable pumps at pumping stations are investigated. The algorithm of calculation speeds of main pumps, when all of them have the same speed of rotation is given. The block diagram of the algorithm is shown
