FIELD: electrical engineering; low- and medium-power synchronous machines primarily used for off-line power plants.
SUBSTANCE: proposed synchronous generator has precision control system, stator windings, and field winding, as well as two bridge rectifiers; field winding is connected to output of first rectifier and control unit, to output of second rectifier; stator winding leads are interconnected in star; auxiliary leads are connected to input of first rectifier. Field winding is made in the form of parallel-interconnected coils which are connected to first-rectifier output. Second-rectifier input is connected to loose leads of stator winding. Control unit is built of regulating assembly and control device. Regulating-assembly inputs are connected to control device through its regulating member and its outputs are connected to field winding. Inputs of control device are connected to second-rectifier output and outputs, to regulating assembly.
EFFECT: simplified design, improved metrological characteristics, enlarged functional capabilities, enhanced reliability.
