摘　　要：针对涡流损耗问题,提出海水中无线电能传输系统参数的设计优化方法,能使系统电能传输效率最优。首先,在海水中通电线圈电磁场分析的基础上,利用涡流损耗等效阻抗,得到海洋环境无线电能传输系统的等效互感模型。其次,在初、次级侧线圈位置固定时,建立涡流损耗等效阻抗与系统工作频率及线圈匝数的关系表达式,并利用传输系统两侧线圈验证了涡流损耗等效阻抗计算方法的可行性。最后,以海水中LCC/S型无线电能传输系统的能量模型为基础,采用粒子群优化算法进行最大传输效率寻优。利用优化参数,搭建实验测试系统,结果显示,在模拟海洋环境中,当传输功率为1 kW时实验系统整体效率可达84%。Aimed at the problem of eddy current loss,a method for the parameter design and optimization of a wireless power transfer(WPT)system in seawater is proposed to optimize the power transmission efficiency of the system.First,based on the analysis of the electromagnetic field of coils under operation in seawater,the equivalent mutual inductance model of the WPT system in a marine environment is obtained by using the equivalent impedance of eddy current loss.Second,when the positions of the primary-and secondary-side coils are fixed,the corresponding relationship between the equivalent impedance of eddy current loss and the operating frequency of the system and the number of coil turns is established,and the feasibility of the calculation method for the equivalent impedance of eddy current loss is verified by using the coils on both sides of the WPT system.Finally,based on the energy model of an LCC/S-type WPT system in seawater,the particle swarm optimization algorithm is used to optimize the transmission efficiency.A test system was built with the optimized parameters,and results show that when it transmitted 1 kW of power in a simulated marine environment,its overall efficiency can reach 84%.
