“…The practice of calculating modern generators for autonomous power supply systems shows [14][15][16][17][18][19][20][21][22][23][24][25] the first method allows reducing ∆U by no more than 5-6%. If the generator voltage drop exceeds the permissible level ∆U, then the second method can also be used, since the increase of В1 by a factor of n with a constant power in the specified generator dimensions and the corresponding decrease of А by a factor of n (to maintain the force unchanged t=А В1) reduces x * by n 2 times.…”

The influence of the harmonic composition of the stator current on the permissible power of an electric machine during its operation in an autonomous nonlinear network is considered. A generalizing equation is proposed for calculating this power, taking into account an increase in the electric losses in the stator winding and losses in the steel of the machine. The analysis of the causes of voltage drop at the terminals of an autonomous generator is made and practical recommendations for its reduction are given for an unexpected change in the load of the generator. The main purpose of investigation is to obtain a generalized expression is derived for calculating the permissible that makes to estimate a reduction of the nominal power of power of alternating current machine when operating in nonlinear networks in condition of knowing harmonics of the stator current. It is usefully for newly created generators and can suppose a changing the operational requirements by the standards for the to the value of transient deviation of the voltage when the load changes suddenly.

A technique for measuring the current-voltage characteristics (IVC) of a nonlinear inertia-free element from the amplitude spectrum of a current curve obtained by decomposing it into a Fourier series is given. The initial data for the method are the curves of current and voltage on a nonlinear element, measured for different points in time. The IVC is represented as a ratio of power polynomials whose coefficients are determined by the Cholesky method. Examples of measurement of the current-voltage characteristics are given, estimates of the relative and absolute error of the approach are given. The advantage of the proposed approach in comparison with the existing ones is the better accuracy of the reproduction of the IVC.
