| Abstract:To meet the requirements of grid connected operation of power turbine generator units，the overall system design，key component selection and automatic power matching control strategy design of variable speed constant frequency（VSCF）device were carried out，and Simulink simulation analysis and experimental verification were completed.The analysis results show that the application of VSCF technology in marine power turbine generator set can reduce the control difficulty of power turbine generator set and improve the power generation quality；Under the automatic power matching control strategy，the power injected into the grid by the VSCF device can automatically change with the change of the mechanical power of the input generator to achieve the automatic balance of the input and output power. |
