INTEGRATED CONTROL SYSTEM OF PIPELINE SYSTEM 'EASTERN SIBERIA - PACIFIC OCEAN - II' (ICS PS 'ESPO-II')

摘要

FIELD: oil and gas industry.;SUBSTANCE: system includes territorial dispatch centres (TDC), regional dispatch centres (RDC) and local dispatch centres (LDC) connected via communication channels to controlled oil-pumping stations (OPS) and performing upper, intermediate and lower control levels and control of three process plants (TU-1, TU-2, TU-3) using IEC-608750-5 protocol. A software-and-hardware complex of the upper and lower levels includes input-output servers, servers of a mathematical model, controllers of algorithms, a video wall, firewalls, and an automated workstation (AWS) of a dispatcher. The software-and-hardware complex of the lower level includes an input-output server of a microprocessor automation system (MPAS) of OPS, an input-output server of linear telemechanics (LTM), firewalls, AWS of an OPS operator, an LTM operator and an oil quantity and quality measurement system (OQMS). A provision is made for an interlock of control from RDC and LDC at control of a technological process of oil transportation from TDC. A provision is made for transfer of a control function to the intermediate or the lower level, as well as return of the control function from the intermediate and the lower level to TDC.;EFFECT: providing reliable and safe oil transfer.;4 cl, 6 dwg
