Development of a fuzzy automated natural gas volume control system for the gas pipeline

The article discusses the problems of the occurrence of unaccounted-for-gas (UAG) during the operation of the gas pipelines. The paper proposes a simple and effective algorithm for the classification of UAG, as well as for the search for the origin of the cause of UAG, which is based on fuzzy logic methods. The article deals with the implementation of a fuzzy system of control and management over the balance of gas volume and the implementation of the algorithm for finding the causes of UAG. The article shows the ways of implementing this algorithm using the example of programming languages of the IEC 61131 standard, and also discusses issues related to dispatching control of gas pipelines, and the role of such systems in controlling the balance of gas volumes.
