Study on power substation operation safety monitoring technology based on UWB location

UWB location technology has high location accuracy and will be widely used in electrical power safety in the future. This article has briefly described the principles of UWB location technology, compared various kinds of wireless location technology and analysis accurate location needs of job safety monitoring in the transformer substation, and then, the UWB location technology applied in substation is feasible. And on this basis, with a 500kV substation, for example, the test environment of substation operation monitoring based on UWB location technology has been established, and substation typical operation scenarios has been tested. According to the test data, the environmental impacts of substation UWB location accuracy have been analysis. And finally, the problems that the UWB location technology applied in the substation operation safety monitoring have been analyzed.
