Abstract

When solving the issues of creation and improvement of power supply systems, calculations of steady-state modes are the most common. Since power supply systems contain nonlinear elements, their steady state mode is described by nonlinear equations. Solving such equations is possible only by iterative methods, which is associated with the problem of convergence of the iterative process. The proposed method calculations of steady-state modes are the most common in solving the issues of creation and improvement of power supply systems, and the algorithms implementing it are relatively easy to program and provide the necessary speed and accuracy of calculations. They are designed to solve a number of practical problems related to the design and operation of complex closed power supply systems. Due to a number of features of electrical systems, which are inherent in the power supply systems of the agricultural and forestry complex, the convergence of the iterative process may be delayed and even not provided. In this regard, the authors proposed a direct calculation method with cyclic correction of the initial information for each cycle in order to take into account the nonlinearity of the elements of the electrical system. The proposed method is based on universal calculation formulas for determining eigenand mutual resistances, which are obtained as a result of transformation and solution of nodal equations
