| 要約: | This project established a reclosing simulation mode on 161kv line with bilateral power source of regional network based on PSCAD, and to do the simulation when the different types of fault occur on the various load condition. On this basis, analysis for the different types of fault occur is done, and effect of various loads of the protection devices in the power system is studied. The key point analysis focused on the effect of residue voltage produced from the induction motor load in case of the transient fault and permanent fault occurred on the transmission line separately. This thesis has analyzed the changing rule of the residual voltage produced from the induction motor when the faults occurred. Hence, a proper reclosing time was identified, and a better control system, which able to improve the residual voltage on the power system protection, was proposed. |
