Allocation Principle and Power Calculation of Grounding Rheostatic Brake Device of Linear Metro

摘要

In order to increase efficiency and reduce wear on wheels and friction brake components, electric brake is been maximum possible used in Linear Metro Vehicles. The grounding rheostatic brake, whose function is to overcome non-receptive problem, was been researched in the paper. This study concentrates on its power issue, with research method of initiating from a single train's run simulation, constructing mathematic model of Linear Metro power system subsequently and researching its numerical arithmetic finally, Newton-Raphson iterative one specially. Simulation results varied with power factor and efficiency of Linear Induction Motor (LIM) were investigated in the end. And allocation principle of grounding rheostatic brake is presented consequently.
