| Abstract: | Based on the simulation tool of MATLAB Simulink,the model of power system transmission lines with V,W two-phase ground fault is established,and the short-circuit impedance is calculated with programming of two kinds of microprocessor-based protection algorithm,then draws out the simulation waveforms,and compares the computational accuracy and computing speed.The results are analyzed and concluded as follows：The model can analyze the error sources of microprocessor-based protection algorithm,filtering performance and the impact on microprocessor-based protection algorithm from various factors,and takes a new measure for microprocessor-based distance protection design and action analysis. |
