East Ohio Gas users benefit from its new SCADA system
Delivering over 280 billion cubic feet of natural gas per year through some 17,800 miles of pipeline, the vast grid of the East Ohio Gas Co. (EOG), Cleveland, requires constant monitoring and control to properly serve 1.1 million customers. The supervisory control and data acquisition (SCADA) system used by EOG has a series of instruments located at strategic intervals along the pipeline. These instruments monitor temperature, pressure, flow, odorization, compressor status, and alarms. Linked to the instruments are a series of 85 remote terminal units (RTUs) that are polled every 15 secs. for data. These RTUs also control the valves and compressors that deliver natural gas. These, in turn, are linked by radio to a series of minicomputer hosts. To revamp its system, EOG needed both new hardware and application software. This paper reviews the decision making process for selecting both hardware and software systems and the resulting performance.
