The application of autonomous electrical complexes with parallel diesel generator sets based on synchronous generators is considered. The problem of the existence of exchange power fluctuations in such technical systems is described. A mathematical model has been developed that allows conducting research of an autonomous electrical complex. It is proposed to implement graphical visualization of the dependence of the amplitude of power exchange fluctuations on time constants in the speed control circuits of diesel generators in the form of configuration maps. An example of using the proposed method for a specific electrical complex is given. The possibility of reducing the amplitude of exchange power fluctuations by reducing the values of time constants of frequency control circuits is justified, which is the basis of a new method for eliminating exchange power fluctuations and makes it possible to improve the method, which is based on changing the transmission coefficients of frequency regulators.
