IEC 61850 based substation automation systems simplify the design, installation and maintenance with significantly reduced cost. Its real-time, security and reliability are of concern and are vital important to the industry. This paper presents the development and application of an established platform for evaluating process bus applications. The evaluation platform consists of a number of GOOSE,...
The introduction of a process bus connection was one of the features that have been added by IEC 61850. Yet - implementations of process bus are non existent in substations supporting IEC 61850 today. One of the hurdles so far was the requirement for accurate time synchronization. Introducing IEEE 1588 finally provides the technology to solve that issue in a smart way by using the communication network...
The paper describes the abstract concept of Process Bus defined in IEC 61850 9-2 and then focuses on the implementation agreement that ensures the interoperability between merging units and protection devices from different manufacturers. The components of the Merging Unit, the requirements for its performance and time synchronization are described. Protection and recording applications based on the...
Increasingly, communications has become a significant component in modern power systems. The recently introduced standard IEC61850, describes the concepts for sub-station communications covering protection, control and metering functions. Not only is this is going to have a major impact on the power systems communications but it will also influence the design of future protection systems. The concepts...
Standard communication protocols have been used for substation automation for many years. The applications are mainly on the station level communication to indicate alarms and events within a substation and make them visible to the operator. However the configuration and implementation of the protocols have differed widely between manufacturers leading to difficulties when attempting to support product...
