Intelligent power distribution room
Model：
Overview：
With the comprehensive transformation and development of power transmission, transformation, and distribution networks, many medium and low voltage distribution network facilities below 35KV have increased significantly, such as switch rooms (switching stations), distribution rooms, box-type switch rooms, etc. It has the characteristics of decentralized construction, wide coverage, diverse geographical environment conditions, and is easily affected by user capacity expansion and urban construction. The deployment of the three-remote automation system (DTU) in the primary and secondary circuits of the power system is already very mature, basically realizing the unmanned operation of the power substation, and instead is a regular inspection system.

  1. The video cloud node has a large-capacity NVR function, which can save on-site video data of more than one month. When there is a failure or poor signal in the on-site 4G public network channel, it will not affect the video data collection.

  2. The video cloud node has strong edge computing capabilities and rich artificial intelligence (AI) algorithms, which can conduct state analysis and estimation for power operation equipment, and intelligent recognition of on-site operation and working conditions.

  3. The gateway configured on the spot reserves the fiber optic Ethernet interface can expand the power line carrier communication port, and supports the standard MQTT communication protocol. In the future, it can be easily connected to the integrated terminal TTU the intelligent station area system, and the power grid property management platform system to realize integrated integration. The main station system not only supports independent deployment, but also supports cloud deployment, and provides a variety of standard interfaces to facilitate integration with other systems on the main station side.

  4. The system station-side equipment, including the gateway, video cloud node, and various chips and devices such as the CPU, MCU, and communication module of sensors, as well as the embedded operating system, are all fully localized.

  5. Advantages: There are two types of Intelligent power distribution room wireless transmission technologies: the American LoRa and the domestic TPUNB. We used TPUNB, which adopts the communication method that the gateway actively polls and measures the sensor (the sensor usually sleeps and is awakened when communicating), important is that the data communication will never conflict, with high communication reliability and efficiency. Compared with Lora, TPUNB itself has less power consumption; the On-site application has a higher communication success rate and efficiency, and the actual working power consumption is much better than Lora.
