| Abstract: | This paper introduces the model of the DC traction power system with Grounding Braking Rheostat.Power net configuration diagram has been built by using MATLAB.Newton Raqhsoo iterative method is used for solving the non linear equations introduced by the node voltage matrix equations in the system.The modeling and the simulation of the entire system is defined as GRBSS(Grounding Rheostat Brake Simulation System).On the basis of the results obtained in the paper for node voltage and current,the power calculation method and allocation principle of the Grounding Braking Rheostat are studied further. |
