Design and Implementation of a UCA based Substation Control System (Mark Adamiak, GE Power Management (Ashish Kulshrestha, KVB-Enertec Inc)

ABSTRACT: With the maturing of the Utility Communication Architecture (UCA), utilities are beginning to implement substation protection and control systems that are based on this technology.
This paper describes such an implementation for the control of the Bateias 525kV substation on the COPEL power system in Brazil.
In particular, the paper will describe the customer's requirements and expectations with regard to the information flow, control sequences, automation functions, and reliability. The design of the substation automation architecture to meet these customer requirements will be presented including the communication network structure, and redundancy software. Also to be discussed will be the installation issues encountered and system performance levels achieved.
In addition to the above, the paper will include a brief tutorial on UCA.

Keywords: UCA2.0, CASM, Substation Architecture, High Availability, Redundancy, SCADA, GOOSE, GOMSFE, IEC 61850
