| Summary: | The design and test of movable DC deicing device with back-to-back VSC-HVDC function are introduced. Main circuit structure of the device is discussed. Carrier phase-shifting control, PWM rectifier control and chopping control for constant current of multiple voltage source converters are designed. Control method of series back-to-back VSC-HVDC is analyzed. The protection strategy and the test scheme of the device are introduced. Test results testify the feasibility and validity of the control method. The device is satisfied with the deicing request of power grid, and is capable of carrying out VSC-HVDC with medium and small power. |
