MODELING OF AUTOMATICALLY CONTROLLED NATURAL GAS COMPRESSION PROCESSES. PART 1. STATIONARY MODES
The issues of modeling of natural gas compression processes in stationary modes are discussed. Modeling is presented as a sequential disclosure of uncertainty regarding causal topology, block structures, and parameters of a controlled technological process and its environment. It is proposed to approximate the compressor characteristics by artificial neural networks. Using the example of parametric identification of a computer model of a compressor line, a conclusion is drawn on the advisability of combining graphical and numerical methods for analyzing stationary modes. The proximity of the model results to the archived data of a real gas pumping unit of the main gas pipeline allows us to conclude that the proposed methodology for modeling, identification and analysis of stationary modes of natural gas compression has prospects for further development and practical application.
