In today’s economic environment, SCADA requirements in the petroleum, Oil & Gas industries are changing at a rapid pace. Clearly, the need for reliable, centralized control and monitoring is more important than ever. The drive to reduce costs, increase system reliability and improve throughput demands effective centralized control. There is also a renewed interest in operational security.
Ten years ago SSGC embarked on a major mission to use technology as a strategic assets and embarked on the use of open-architecture, distributed-intelligence and platform independent SCADA systems.
In the first phase of this effort this effort the Transmission network of SSGC saw the use of Modbus protocol based PLCs running AGA-3/7 analysis for both flow and compressor performance monitoring. Block valve control was implemented shortly thereafter. LAN based redundant Host systems at Karachi and Shikarpur provided both online and historical data.
In the second phase SSGC is now undertaking a distribution SCADA systems that will provide for custody Transfer, Load Forecasting, Gas Analysis and other Gas Management functions.
In the execution of the Distribution SCADA system the Transmission and Distribution SCADA systems will be integrated. This will facilitate a seamless exchange of data between the different parts of SSGC resulting in streamlined reporting and higher efficiency.
