Abstract
A thermal-power power electronic direct-hung energy-storage plant backup power system includes a thermal-power grid connection startup/standby unit, a power electronic energy-storage switching unit and a thermal-power plant unit. The thermal-power grid connection startup/standby unit is connected to the power electronic energy-storage switching unit and the thermal-power plant unit, respectively. The power electronic energy-storage switching unit is connected to the thermal-power plant unit. The power electronic energy-storage switching unit includes an energy-storage device, an energy-storage device converting apparatus, an energy-storage device isolation switch, an energy-storage Power Electronic Transformer (PET) low-voltage Alternating Current-Direct Current (AC-DC) converter, an energy-storage PET low-voltage side filter capacitor, an energy-storage PET high-frequency DC-DC transformer, an energy-storage PET high-voltage side filter capacitor, an energy-storage PET high-voltage DC-AC converter, an energy-storage grid connection switch, a low-voltage standby energy-storage power supply busbar, and a high-voltage standby energy-storage power supply busbar.
