Control of synchronous machines set with microprocessor-controlled excitation units in high-voltage tests station

摘要

The paper presents idea and implementation of the control of synchronous motor-synchronous generator machines set used for supplying the high-voltage test station in the electhcal equipment repair and service plant. In the excitation circuits of both machines the microprocessor-controlled excitation units were used. Possibilities of generator output voltage regulation by the field current control in the synchronous state of operation were introduced. Simulation model of Matlab-Simulink and results of simulation research was shown. Exemplary realization was disclosed. Verification measurements of the real machines set in the start-up process and synchronous state of operation were presented and discussed.
