Abstract :
A superconducting magnetic energy storage (SMES) unit consisting of a voltage source converter (VSC) and a chopper is used to damp the oscillation of a synchronous generator. The state feedforward decoupling method based on synchronous frame is used to improve the dynamic response of the VSC. The work modes of the chopper are discussed, and a small signal model of the chopper is established for the regulator design. Simulations and experimental results demonstrate the dynamic performance of the SMES unit.
