INFLUENCE OF BACKLASH ON AMPLITUDE OF EXCHANGE POWER FLUCTUATIONS IN AUTONOMOUS ELECTRIC POWER EQUIPMENT

Abstract

The application of autonomous electric power equipment having in their composition parallel operating diesel-generator sets on the basis of synchronous generators is considered. The problem of existence of exchange power fluctuations in such technical systems is described. A mathematical model has been developed that makes it possible to carry out investigations of an autonomous electric power equipment. The technique for constructing maps of the amplitude of the exchange power fluctuations, from the backlash gaps in the speed control circuits of diesel generators is obtained. The use of such cards makes it possible to introduce recommendations on limiting the amplitude of exchange power fluctuations to normative documents, both of a general nature, and specifically for certain types of equipment. In the same way, the cards make it possible to determine the gap gaps existing in the frequency control loop from the measured amplitudes of the exchange power fluctuations.
