Simulation research on super-synchronization speed control technology of 80 MVA motor generator

The super-synchronization speed control assemblies (SSSCAs) of two 80 MVA motor generators (MGs) in HL-2A Tokamak are introduced basically. The analog control system of each SSSCA will be digitalized. In this paper, basing on rotor cycloconverter circuit, the main control technology of the SSSCAs including vector control, voltage feedforward control and discontinuous-current compensation are analyzed. The simulation models of the SSSCA with control technology have been built by power simulation (PSIM). The simulation result shows that the control system models with these control algorithms can control the MG speed, the amplitude and frequency of the motor rotor current well to realize super synchronous speed regulation of the MG. The control algorithms can be used as an important reference for digitalizing the control system of the SSSCA.
