Structural Optimization of Grading Ring for Ultra High Voltage Composite Insulator by Combining Finite Element Method and Particle Swarm Optimization Algorithm
摘要
Abstract
Due to complex structure and high voltage level,the V-and I-type composite insulators used in AC 1 000 kV single-circuit tangent power transmission tower are much easier to produce serious corona.Consequently,we established a three-dimensional model for these composite insulators and calculated the electric field by software ANSYS.Moreover,we adopted the ANSYS parametric design language（APDL） to realize a particle swarm optimization（PSO） algorithm.Meanwhile,we used submodeling technique to solve such huge computation problem due to complexity of used mode,which could effectively reduce calculation amount without lose of accuracy.The results show that,maximum electric field strength of corona ring used in V type insulator and on insulator surface is about 13.9% and 29.2% higher than that of I type respectively,and the method combining finite element method（FEM） and PSO algorithm is quite suitable for such grading rings structure multi-parameter optimization problem.Finally,the maximum electric field located on surface of ring and insulator shed can meet the requirements of electric control value,and no corona discharge can be observed when grading rings are used in actual project.The proposed method can solve structure optimization problem for large field domain and multi-media complex model.关键词
