The Applications of Wireless Sensor Network in Smart Substation

The electrical substation consists of many smart devices to monitor operating environment or control power facilities etc., which requires various sensors, such as temperature and humidity sensor, SF6 sensor etc, to organize as a wireless sensor network (WSN) to cooperate for intelligent operation. In this paper, we design an architecture of WSN for the smart substation, and introduce the applications in detail, including the temperature, humidity, waterlogging, SF6 gas and leakage current and 3D holographic visualization. The operation shows our solution can effectively sense the environmental object and monitor the substation assets.
