Enhancing traditional process SCADA and historians for industrial & commercial power systems with energy (via IEC 61850)

Abstract

Coordination of large scale distributed measurement and control systems, such as Supervisory Control and Data Acquisition (SCADA) and other process control system implementations, require reliable and robust networks that can connect thousands of remote devices from multiple remote locations. Additionally, many heavy industries have ever increasing demands of their infrastructure to handle more network services and deliver a full spectrum of control and monitoring of thousands and even tens of thousands of points within their global business operations. This paper will outline a new novel method of providing a convergent use of the IEC 61850 protocol, within process control networks, to provide a more deterministic type of process control, monitoring and energy management. The benefits of real-time archiving of process values, process messages, Intelligent Electronic Device (lED) status and alarm data along with process batch data can be achieved in an advancement of traditional historian based systems. This new approach, providing traditional downtime reports and alarm summaries for maintenance purposes along with the added benefits of providing the opportunity for highly accurate and time synchronized energy consumption and energy balance data along with efficiency reports of various different production or process operations. index Terms-International Electrotechnical Commission (lEC) 61850, intelligent electronic device, process historian, OLE DB, historical data trending, Supervisory Control and Data Acquisition (SCADA) I.978-1-4799-3309-9/14/$31.00

Large Scale Motor Group Integrative Management and Control Network System Based on PLC-SCADA under Complex Environment

“…We make full use of the characteristics of PLC and SCADA and bus, internet, designs the hardware and software of large scale motor group integrative management and control network system based on PLC-SCADA under the complex environment. Of course, it can carry on the precise control of the other process parameters such as temperature, pressure, flow, level, composition, or industrial process such as chemical process, metallurgical process, port logistics, and so on [13] [14].…”
