Presentation: Self-sensing technology based on multiphysics collaboration and its application in online monitoring of overhead transmission lines
Although artificial intelligence is rapidly becoming powerful, and is being widely applied to condition monitoring and diagnosis of electrical equipment. There are still many situations where sensors cannot be installed, such as in extreme environments with strong electric fields and limited space. For commercial devices, most data are from normal condition. The effective data under defects or malfunctions are insufficient to support the analysis by artificial intelligence. Therefore, during a certain period of time, numerical methods still play important role. With the help of numerical model of multiphysics field, a sensor can monitor multiple parameters, the range of monitoring is expanded, and even some components of device itself can be used as sensors. With the help of numerical model , the demand for data can be significantly reduced, and the physical meaning can be clarified. In this presentation, an application of the numerical model of multiphysics field in the online monitoring of overhead transmission lines will be introduced. With the help of numerical model of multiphysics field, a multifunctional self-monitoring method is developed that uses electromagnetic induced signals in ground wires of overhead transmission lines to comprehensively detect multiple abnormal states, such as lightning strikes, short circuits, icing, ice shedding, gallop, and dynamic line rating. Therefore, the ground wires are not only used for lightning protection, but can also serve as multifunctional sensors. The proposed method can offer comprehensive advantages, including multifunctional monitoring capabilities, wide monitoring range, cost-effectiveness, simplified installation/maintenance, unaffected by harsh weather, and self-powering functionality.
