Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Integration of information data streams to solve the problem for assessing the capacity of gas in underground storage in the supervisory system «Gazprom UGS» EVSEEV D.Y. Fluctuations in gas consumption determines the need to use to smooth seasonal peak consumption of gas, underground gas storage (UGS). Management and operational control modes distributed UGS is centralized production and dispatching. Automating the process is characterized as a different level of integration of SCADA and diversity of sources of information used in the management process. DCS does not have complete information about the target operating conditions, technological complex in and of themselves do not solve the problems of decision support. In particular, they do not measure the gas flows and bandwidth terrestrial technological complex UGS without integrating data from related, including higher systems. The paper proposes a design solution of the problem of data integration on the example of dispatching control module (control) information management system «Gazprom UGS», built on the basis of program complex PSIControl company PSI AG. Keywords: information data flow, UGS automation, dispatcher control, control level, ICS, SCADA, MES, ERP, SAP ERP. Contacts: E-mail: Evseev@atgs.ru Pp. 27-34.
