摘　　要：为了解决现有的高压直流输电线路电场强度值模拟方法存在模拟完整度较低、误差较大的弊端,提出一种基于有限元法的高压直流输电线路电场强度值模拟方法。该方法引入有限元法并优化,以此为理论基础,根据高压直流输电线路电场强度值模拟的需求对有限元软件ANSYS进行设计,以实际高压直流输电线路为基础构建高压直流输电线路模型,基于此,采用有限元软件ANSYS实现高压直流输电线路电场强度值的模拟计算。实验结果表明,与现有的高压直流输电线路电场强度值模拟方法相比,所提方法能够提高模拟完整度、降低模拟误差,充分说明所提出的高压直流输电线路电场强度值模拟方法具备更好的模拟性能。In order to solve the drawbacks of the existing simulation methods of HVDC line electric field strength,such as low simulation integrity and large error,a simulation method of HVDC line electric field strength based on finite element method is proposed.Based on the theory of finite element method and optimization,the finite element software ANSYS is designed to simulate the electric field intensity of HVDC transmission line.Based on the actual HVDC transmission line,the model of HVDC transmission line is constructed.Based on this,the finite element software ANSYS is used to realize the simulation calculation of electric field intensity of transmission line.The experimental results show that the proposed method can improve the simulation integrity and reduce the simulation errors compared with the existing methods for simulating the electric field intensity of HVDC transmission lines,which fully demonstrates that the proposed method has better simulation performance.
