| Abstract: | The protection study for the Transformers and transmission lines is an important part of the power system protection study. Transformer simulation model and transmission lines simulation model were build by using Matlab Simulink and SimPowerSystems toolbox. In the simulation model, choose M-file to write S-function for custom Simulink blocks of transformer differential protection and transmission lines distance protection. Achieve the simulation and research of digital differential protection and transmission lines distance protection by means of Matlab. Movement behavior of the simulation has been verified. |
