Next Generation Automation: Effective Platform Design and Practical Implementations
There are a number of challenges in meeting the defined NIST architecture while driving interoperability. Application modularity, integration with existing enterprise data models, leveraging existing enterprise architecture and supporting increasing volumes of diverse field data (including meter data, phasor measurements, traditional telemetry for operations, power quality and new remote sensing devices) are among some of the key challenges today.
This paper describes a service-oriented architecture for data acquisition and control leveraging some of the latest concepts in software engineering. By addressing the business requirements to support role-based applications and services, the platform removes the “islands of automation” issue and allows a vertical decomposition of the application stack to lower the barrier to entry for new applications. The platform supports horizontal scalability for performance and is distributed, by design, for reliability and high availability. In addition, this paper addresses the detailed design issues around support, performance, reliability, security and scalability.
Finally, we will showcase a practical implementation of the basic concepts of data acquisition and control while leveraging an industry standard enterprise data model to support interoperability between heterogeneous systems. This platform design shows how today’s well defined standards coupled with emerging standards can be leveraged in a modular approach to minimize the customer’s risk and reduce overall development support for vendors.
