摘要：為優(yōu)化用于監(jiān)測(cè)光伏板覆冰厚度的叉指電極式傳感器結(jié)構(gòu)參數(shù)，增大傳感器覆冰監(jiān)測(cè)性能指標(biāo)，提出了一種考慮多因素共同作用的正交試驗(yàn)設(shè)計(jì)方法。通過 comsol 有限元仿真軟件建立了一種處于覆冰狀態(tài)的 3D 叉指電極模型，并使用三維有限元法，對(duì)叉指電極的金屬化因子、叉指間距、叉指長(zhǎng)度和叉指對(duì)數(shù)進(jìn)行單因素仿真分析和多因素作用正交試驗(yàn)。選取上述四個(gè)參數(shù)為優(yōu)化變量，以電極電容值、靈敏度和最大探測(cè)深度作為性能評(píng)判指標(biāo)，得到了四種結(jié)構(gòu)參數(shù)對(duì)電極性能影響主次關(guān)系以及電極結(jié)構(gòu)參數(shù)最佳正交優(yōu)化組合，并將電極結(jié)構(gòu)參數(shù)優(yōu)化前后進(jìn)行覆冰性能對(duì)比。結(jié)果表明，電極最佳參數(shù)組合為電極金屬化因子0.6、叉指間距0.3 mm、叉指對(duì)數(shù)12 對(duì)、叉指長(zhǎng)度80 mm，電極電容值增加87.25%、電極靈敏度增加98.6%、電極探測(cè)深度增加2.3%、電極尺寸減少24.7%。該方法能夠有效提升叉指電極在覆冰監(jiān)測(cè)中的性能。

Abstract: In order to optimize the structural parameters of the interdigitated electrode sensor used for monitoring the thickness of photovoltaic 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 performed 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 structural 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.

Key words: interdigitated electrode; orthogonal test; ice monitoring; sensor structural parameter
