Aiming at the need of online intelligent perception in substations, this paper designs and researches wireless sensor networks in substations. Apply the magnetic resonance wireless energy transmission technology, select the LCL-S circuit topology according to the circuit characteristics, design its charging scheme for wireless sensor nodes, and explain its applicability and advantages. Then, according to the characteristics of the substation, a wireless sensor network deployment scheme for the substation is proposed. Aiming at this scheme, the ant colony algorithm is used to design the wireless charging strategy of sensor nodes. The results show that the charge planning strategy based on the ant colony algorithm can ensure the overall and continuous operation of the substation wireless sensor network, and effectively reduce the energy consumption cost of the entire wireless sensor network.
