Open-Source Implementation of Monitoring and Controlling Services for EMS/SCADA Systems by Means of Web Services— IEC 61850 and IEC 61970 Standards

This paper presents an implementation of monitoring and controlling services for energy-management system/supervisory-control-and-data-acquisition systems, based on IEC 61970 and IEC 61850 international standards. The proposed solution is based on web services technology that enables the typical advantages of an open-source framework, such as applications decoupling, applications integration, reduction of upgrading costs, reuse of existing infrastructures, and ease of development. Standardized interfaces are provided by the generic interface definition interfaces of IEC 61970. The web server that has been developed has been tested in a simulation environment where the physical devices of a generic power system were simulated with databases whose data models were provided by the common information model of IEC 61970.

I. Introduction

The major objective of this paper is to present an implementation of monitoring and controlling services for energy-management system/supervisory-control-and-data-acquisition (EMS/SCADA) systems, based on the IEC 61970 and IEC 61850 international standards and on open-source technology.
