The reporting and the generic object oriented substation event(GOOSE)are two important functions usually used in IEC 61850. In order to distribute the report-control-block and obtain the GOOSE subscription information

the statically configuring method is adopted in the existing projects. However this method not only demands the additional constraint rules

which are out of the IEC 61850 standards

but also makes the information inconsistent sometimes. This paper realizes the connection between the server access point and the client

and the rules of enabling and owning report-control-block are defined. According to the rules the report-control-block can be dynamically allocated. By the services provided in IEC 61850

such as getting the directory service

the data definition service

and the GOOSE-control-block attribution value service

the GOOSE subscription information can be obtained dynamically. It is pointed out that the interoperability of IEC 61850 is improved by using the dynamical way to allocate the report-control-block and obtain the GOOSE subscription information

meanwhile the dynamic service characteristics of IEC 61850 is expressed in a better way

and all these are good for promoting the application of IEC 61850 standards.This work is supported by the Electronic Information Industry Revitalization and Technical Transformation Projects of the Central Budget Investment Plan in 2013(No. 20131125).
