High speed power generator for low power steam turbine

Abstract

The paper discusses the issues of creating a high-speed power generator for a low-power steam turbine. A 50 kW power generator with a rated speed of 12,000 rpm was developed. The influence of control parameters on the power generator performance was analyzed. The electromagnetic processes in the power generator were mathematically modeled. For the single-pulse control algorithm used in the generation mode, rational ratios of the angles of the beginning and end of the voltage pulse were established. The analysis of the obtained results shows that the developed power generator meets the set requirements for joint operation with a steam turbine. The choice of a valve-inductor machine for this purpose makes it possible to significantly simplify the design, reduce the costs of production and improves the reliability of the system as a whole. The peculiarities of the implementation of control algorithms make it possible to use a minimum number of sensors and not to use the rotor position sensor.
