摘　　要：在线监控设备的稳定供电问题一直是制约输电线路智能运维技术发展的瓶颈。使用静电感应和感应补偿从高压架空输电线路的绝缘地线汲取功率,可能有望成为解决此问题的方法之一。本文在此前提上,首先介绍了地线取能的等值电路的推导方法,之后分析了在负载及取能等值参数变化下的调谐取能策略,最后使用Multisim软件,仿真了对地电容、调谐电感以及负载电阻变化的情况下的稳压取能回路输出。仿真结果表明在取能回路等值参数变化下,稳压电路可以实现将输出电压稳定在12V左右。The stability of large-scale online monitoring equipment and the problem of high-power supply have always been the bottleneck restricting the development of intelligent operation and maintenance technology for transmission lines.Using electrostatic induction and induction compensation to draw power from the insulated ground wire of high-voltage overhead transmission lines is expected to be a possible solution to this problem.On this basis,this paper first introduces the derivation method of the equivalent circuit of the ground line energy acquisition and the correction method of the line parameters under the consideration of the sag,and then analyzes the tuning energy acquisition under the change of the load and energy equivalent parameters Finally,the Multisim software was used to simulate the output of the voltage-regulating and energy-retaining loop with the change of the capacitance to ground,tuning inductance and load resistance.The simulation results show that the constant voltage circuit can stabilize the output voltage at about 12V under the change of the equivalent parameters of the energy acquisition loop.
