新型电力系统干式空心平波电抗器包封绕组的电动力分布特性
Electrodynamic force distribution characteristics of encapsulation winding of dry-type air-core smoothing reactor in novel power system
摘要
Abstract
Under the new energy convergence of the novel power system,the harmonic content of the converter sta-tion increases,and the dry-type air-core smoothing reactor will face more complex operating conditions,and the en-trapped winding electrodynamic force caused by it will be an important cause of the reactor failure.This paper ana-lyzes the harmonic characteristics of the valve side of the converter station under the new energy collection of the no-vel power system,and studies the electrodynamic distribution characteristics of the encapsulation winding of the dry-type air-core smoothing reactor under the condition of DC and multiple harmonic superposition.Firstly,based on Fourier analysis,the harmonic characteristics of dry-type air-core smoothing reactor in operation are obtained.Then,the mathematical model of the reactor is established,and the electrodynamic distribution characteristics un-der different operating conditions are studied by the finite element analysis method of field-circuit coupling.The re-search shows the superposition of multiple harmonics makes the magnetic field and electrodynamic force of the reac-tor winding unevenly distributed,and the radial electrodynamic force of a layer is significantly higher than that of the adjacent layer winding.Under the action of alternating magnetic field,the overall radial electric force of the re-actor increases by 3 times,and the axial electrodynamic force increases by 4 times.The above research results can provide reference for insulation fault analysis and insulation structure improvement of smoothing reactors in novel power system.关键词
