Study on power system heterogeneous graphics exchange based on IEC 61968 location package and SVG

Abstract

The diversity of graphics models and data models in the electric utility software environment leads to much repetitive work and impede information sharing greatly. CIM in IEC 61970 defines most of the main objects in the electric utility enterprise, which can facilitate data exchange among heterogeneous applications. Howerver, with the development of power system, graphics information exchange among heterogeneous applications becomes more and more desirable. By analyzing two graphics exchange approaches proposed by CCAPI, the way to exchange graphics information in a standardized form combining IEC 61968 Location package and SVG is introduced. An asynchronous graphics exchange mechanism based on publish/subscribe architecture is proposed, which can greatly reduce the redundancy information and enhance the exchange efficiency.
