Optimization Design of Interdigitated Electrode Ice Monitoring Sensor Based on Orthogonal Test
In order to optimize the structural parameters of the interdigitated electrode sensor used for monitoring the thickness of pho-tovoltaic panel ice cover and to increase the performance index of the sensor for ice cover monitoring,an orthogonal experimental design method considering the joint effect of multiple factors is proposed.A 3D model of the interdigitated electrode in an ice-covered state was established by comsol finite element simulation software,and one-factor simulation analysis and multifactor effect orthogonal tests were per-formed on the metallization factor,interdigital spacing,interdigital length and interdigital logarithm of the interdigital electrode using the 3D finite element method.The above four parameters were selected as the optimization variables,and the electrode capacitance value,sensitivity and maximum detection depth were used as the performance evaluation indexes,so that the primary-secondary relationship of the four struc-tural parameters on the electrode performance as well as the best orthogonal optimization combination of the electrode structural parameters were obtained,and the electrode structural parameters before and after the optimization of the ice-covering performance were compared.The results showed that the optimal combination of electrode parameters was electrode metallization factor 0.6,distance 0.3 mm,number of interdigitated pairs 12 pairs,interdigital length 80 mm,electrode capacitance increased by 87.25%,electrode sensitivity increased by 98.6%,electrode detection depth increased by 2.3%,and electrode size decreased by 24.7%.This method can effectively improve the performance of interdigitated electrodes in icing monitoring.
