Online monitoring is the precondition to achieve state maintenance and lifecycle management in power grid. Also, effective data transform model is the basis of online monitoring. We propose a data transform model for intelligent substation and PMS device online monitoring based on analyzing Standards of intelligent substation and State Grid. The PMS data are classified and compared with data model of IEC 61850 Standard. With methods of tag mapping and ID index we achieve the data conversion between intelligent substation and PMS.
A new Brillouin optical time domain reflectometry (BOTDR) based on parallel computing method to extract the spontaneous Brillouin scattering spectra is proposed. By use of parallel computing method, the speed of digital signal processing unit in the new BOTDR can be improved by more than 40 times, which benefits dynamic measurement of the temperature and/or strain along the fiber under test.
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.
