Abstract：
 The invention discloses a power stabilizer of integrated wind power that is based on active voltage source direct current power transmission and belongs to the technical field of power network power stabilizer. The invention is a device that is used for stabilizing the power of integrated wind power and is based on active voltage source direct current power transmission, and the stabilizer comprises a rectifier, an inverter, an energy storage device, a DC bus and a controller. In steady-state operation, the voltage source direct current power transmission transmits wind power to power networks, and at the same time compensates the dynamic fluctuation of the wind power through the energy storage device that is connected in parallel on the voltage source DC bus, so that the power of the wind power that is input into the power networks through the voltage source direct current power transmission is stable. When the power networks are in fault, the active power and the reactive power that are input into the power networks are adjusted, and the steady operation performance of the power networks is enhanced. The device solves the problem that the dynamic fluctuation of wind power is influenced by input power networks, improves greatly the stabilization of integrated wind power and bears great significance in the energetic development of wind power generation.
