A 3D modeling of direct current system

Simulation models of a direct current system with accommodation of an uninterrupted power system's equipment in working area when storage batteries arrangement on shelves were developed. Simulated investigation of a system operation taking into account electric main parameters in mode of a short-circuit failure downstream by condition MATLAB was performed. The electric main structured parameter optimization was done in terms of technic and economic exponents. A key equipment of electrical power system was selected. An automate choice method of breaker assembly was suggested on the results of a simulated investigation in transient state.
