【 摘 要 】

Since IEC 61850 became the widely used standard for substation communication with a lot of implementations, advanced approaches became applicable. Setting groups (SGs) are such a topic. The concept of SGs is known for a long time and was used in IEC 60870-5-103 already. IEC 61850 extended to approach. This study describes the definitions made within the standard. The SGs services have a relation to another concept in IEC 61850's data model – the logical device hierarchy with its Data Object GrRef. Also, these definitions and their impact on behaviour or IED will be described. The main topic is the practical implementation. Starting with the concept of a utility which will be described the requirements for IEDs and testing equipment will be carved out. Changing and controlling the SGs is a client's task. This study describes the implementation of an IEC 61850 client in testing solutions. An implementation example available in testing software will be presented. Available protection parameters in IED's data model offer a wide range of advanced testing and supervision possibilities. The solution proposed enhances the reliability of the grid and enhances the quality of testing. Implementation of adaptive protection is possible.
