The novel tester of digital protective relay based on IEC61850 is proposed in this paper. The tester's system architecture is based on multi-CPU (CPU+DSP) high speed hardware platform and real time operation system, it can receive and sample the analog test data on time, which is then converted into digital test data according to IEC61850 protocol. This tester also has the GOOSE trip signal which...
GOOSE mechanism provides new method for equipping 10kV fast busbar protection with its rapidity, feasibility and flexibility. This paper introduces the scheme of 10kV fast busbar protection and the differences between method of traditionality and method with GOOSE technology. Based on an experiment operated, some complete analysis conclusions are made, and which show the fast busbar protection technology...
