In an application package MATLAB was made visual model of the system of power supply of electic train with the uneven active-inductive loading in each of three phases. For currents symmetrization and reactive-power compensation balanced interphase condensers were included in the system of power supply. For determination of optimum values of condensers capacities at which spherical metric, namely, square root from the sum of squares of reactive-powers, arrived at the minimum value, response surfaces were built. Thus taking into account that circumstance, that in MATLAB application is possible to build line of equal levels just for function of two variables, three diagrams were built. In each of diagrams one of three values of condensers was fixed, and was equal before found optimum value. As a result of construction of lines of equal level without implementation of optimization the geometrical place of values of balanced condensers at which reactive-power in the system of power supply reached minimum valueReferences
