摘　　要：本文基于TCR远程监测系统,利用相应的感应电压幅值包络模型,在分析补偿电容不同容值对感应电压幅值包络影响规律的基础上,建立补偿电容容值与感应电压幅值包络间的映射关系,以此实现补偿电容容值的在线估计。实验表明,本文所提方法能够对补偿电容的容值进行准确估计,且具有计算速度快、鲁棒性强等优点,对分路电阻和道砟电阻的波动不敏感。Based on TCR remote monitoring system and using the corresponding model of induced voltage amplitude envelope（IVAE）,this paper established the mapping relationship between capacitance of compensation capacitor and IVAE,built on the analysis of the influence of different capacitance of compensation capacitor on IVAE,to realize the on-line estimation of the compensation capacitance.Experimental results showed that this method proposed in this paper can accurately estimate the capacitance of compensation capacitors with fast calculation speed and strong robustness,and is not sensitive to fluctuation of shunt-resistance and ballast-resistance.
