摘要
Abstract
As the nonlinear load power increases,the harmonic distortion problem in power systems is serious. The com⁃mon nonlinear load is discussed in this paper. A complete nonlear load simulation model was constructed to supply power to asynchronous motor by the rectifier frequency circuits and a transformer converting 110 kV to 400 V. Only the harmonic distortion rate of the third phase bridge rectifier circuit module is more than 32%,but harmonic components is greatly reduced by adding a harmonic elimination module in the model. The simulation results show that the total harmonic distortion rate of the nonlinear load is not more than 1.40%,which complies with the relevant state standards,and provides a theoretical base of harmonic pre⁃vention and control for enterprises.关键词
