SYNCHRONOUS ENGINE IN FREQUENCY CONTROL
Abstract:

The result of calculation and analysis of properties of salient pole synchronous driveat adjusting of frequency of rotation by the change of frequency of feeding tension at the law of adjusting is resulted . Office hours both at the direct current of excitation are considered and permanent power-factor. For the transferred modes comparative graphic dependences of operating indexes of engines are represented: V-mode descriptions; overheats of puttees of excitation and stator, steel of stator; current in armature winding and excitation, complete losses, output-input ratio and power-factor at the change of moment of loading.

Descriptions of the thermal state of separate areas of machine allow to define maximum the possible loading of machine, and power indexes - to compare efficiency of different ways of adjusting.
