摘要
针对在线监测设备在输电线路巡检中的续航不足、维护成本高以及巡检频次不足等问题,本文设计使用一种U型三线圈无线供电系统同时提出一种基于遗传算法的参数设计优化方法,以实现110 kV中远距离输电杆塔在线监测设备无线供电。在此基础上首先构建U型三线圈无线电能传输系统的电路模型,推导出输出功率、传输效率与负载阻抗、线圈互感、耦合系数之间的关系式,然后通过遗传算法对相关参数进行优化并得到最优解及其对应的参数值。最后根据仿真数据参数搭建实验平台,实验结果表明U型三线圈输电杆塔在线监测设备无线供电系统在380 kHz的工作频率及1.2 m传输距离下,系统输出功率达到81.19 W,验证了其能够满足在线监测设备的供能需求。
Aiming at the problems of insufficient range,high maintenance cost and insufficient inspection frequency of online monitoring equipment in transmission line inspection,this paper designs a U-type triple-coil wireless power supply system using a U-type triple-coil wireless power supply system and at the same time proposes a parameter design optimization method based on a genetic algorithm in order to realize wireless power supply of online monitoring equipment for 110 kV medium and long-distance transmission towers.On this basis,the circuit model of the U-type triple-coil wireless power transmission system is firstly established,and the relational equations between the output power,transmission efficiency and the mutual inductance of the coil,coupling coefficient,and load impedance are deduced,and then the genetic algorithm is used to search for the optimization of the parameters and obtain the optimal solution and its corresponding system parameter values.Finally,an experimental platform is built according to the simulation data,and the experimental results show that the wireless power supply system for on-line monitoring equipment of U-type triple-coil transmission towers achieves an output power of 81.19 W at an operating frequency of 380 kHz and a transmission distance of 1.2 m,which verifies that it can meet the power supply requirements of on-line monitoring equipment.
