Research on the Substation Intelligent Protection System for Operations Personnel Based on the UWB Positioning Technology

In order to improve the safety of the operations personnel, the authors designed the substation intelligent operations protection system, studied the positioning technology, three-dimensional geographic in- formation technology and other key technologies, proposed the technical solutions of the positioning base station, the positioning label and the power supply system, and then derived the technical architecture of the substation intelligent operations protection system, which consists of the infrastructure layer, the support layer, the business layer and the presentation layer. These four layers are used to achieve the task management, real-time monitoring warning sign, area delineation, track playback and other functions.
