ANALYSIS OF REQUIREMENTS FOR GAS FLOW CONTROL SYSTEMS IN GAS DISTRIBUTION PIPELINES

The article deals with the main requirements for the gas flow control system in regional gas pipelines specified by regulatory documents. Particular attention is paid to the requirements of the technical regulations on measuring instruments and state standards of Ukraine for measuring equipment at natural gas metering units, such as gas meters, calculators and volume correctors. The requirements for the climatic operating conditions and power supply of these devices are determined. It is shown that safety during the operation of equipment containing electronic and electrical components in explosive environments is achieved through the use of intrinsically spark barriers. Possible data acquisition and communication technologies that ensure continuous monitoring, rapid fault detection and remote control are considered. In particular, automated data acquisition systems (SCADA) and programmable logic controllers (PLC) are considered, which allow operators to obtain accurate real time data, analyze it and make informed management decisions It is noted that based on the analysis of data stored in the memory of gas metering equipment, using mathematical models, it is possible to perform predictive calculations of consumer gas consumption depending on operating conditions and internal factors such as temperature, pressure and consumption volume. Keywords: gas consumption, calculator, corrector, meter, intrinsic safety barrier.
