Precise Generators Synchronization a Small HPP with an Excitation System

A. Tsolov

Abstract


The main problem in the process of synchronization of small synchronous generators in HPPs is the maintenance of a constant difference in the angular velocities of the generator and the system (sliding). This is necessary for the correct operation of any automatic accurate synchronization algorithm. This article proposes a method based on the combined action of the excitation system and the speed regulator of synchronous generators. The results provide a basis for the practical implementation of the proposed algorithm relevant for mathematical and physical research.
