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.
