The Development and Application of Intelligent Testing System for Relay Protection Based on IEC61850

摘要

We have developed the IED device's Intelligent Testing System for the lack of existing field-testing techniques. The system can automatic access to the tested IED's configuration parameters by simulating the MMS service. It can use the parameters to set the test parameters of the process layer and tests the IED. The system can also intelligently analyze behavior and results of IED using the MMS network packets. It has achieved the intelligent testing for intelligent substation's relay protection.
