Research on Electromagnetic Wind Energy Harvester for Power Tower Inclination Detection
Inclination detection of power towers is an important means to ensure the safe and stable operation of high-voltage transmission line systems.Currently,state monitoring devices have issues such as high power consumption and reliance on chemical batteries for power.This study designs an integrated self-powered tower inclination wireless sensing system,which collects wind energy from high-altitude towers through an electromagnetic energy harvester.The collected energy is stored and supplied to the load by a low-power energy management circuit.The performance of this system was verified by electromagnetic simulation and experiments.The harvester can start at a wind speed of 2 m/s,and at a wind speed of 8 m/s,the voltage of the device in a no-load situation is 1.25 V,with an output power of 8.2 mW.A low-power energy management circuit was built using the BQ25570 chip,and after boosting,it outputted 3.3 V to power the inclination sensor.According to the experimental results,this device can power tower inclination sensors or other small electrical equipment,providing technical support for self-powered IoT wireless sensor network nodes.
