Research on Fire Control Strategy for Unattended Power Substation Based on Ubiquitous Electric Power Internet of Things

[Introduction] In order to enhance the self-rescule ability under fire conditions of the 110 kV powder substation, a fire-fighting strategy is proposed based on the ubiquitous electric power internet of things (UEP-IoT) technology. [Method] The framework of its four layers, including perception layer, network layer, platform layer and application layer was presented. The methodology on how to arrange the fire detecors, fire-extinguishing installations as well as smart management platform were explained. A detailed scheme on how to bulid the fire control system based on UEP-IoT of the 110 kV outdoor substation was given as an example. [Result] By combing the wireless sensor technology and the central management platform, the system can realize multi-level alert and self-rescue for the protected substation. [Conclusion] The results from this study will provide a valuable sample for future substation fire-fighting system design
