The four arms crawler substation inspection robot system was developed, using the integrated navigation technology including laser and odometer, then the robot can run free without the limitation of the road environment and the fixed track; using the image enhancement technology in the complicated environment, improve automatically detecting identification accuracy of the substation equipment status in the bad environment, so the substation inspection robot can implement inspection in all area of the transformer substation, as well as has environment adaptability, engineering construction convenience and the higher promotion application value.
Load stress test of secondary equipment network is important for the large-scale construction of smart substations. In this article, several secondary equipment network schemes and their influence on relays related IEDs are discussed, and then stress test objects, principles for smart substation are proposed. Based on embedded CPU and large-scale FPGA, load stress testing device for secondary equipment network in smart substation is implemented with characteristic of supplying multi-type stress data stream along with IEDs' necessary working stream, and field test practice is introduced in the end.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
