【Abstract】 To solve voltage sag, voltage swell and three phase voltage unsymmetry, a mathematical model of ultrlacapacitor energy storage system based on equivalent circuit is built and a kind of dynamic voltage conditioner (DVC) based on ultracapacitor energy storage is designed. Using ultracapacitor as the energy storage component at DC side of the DVC, the decoupling and feed forward compensation control of the DVC are implemented by bi-directional voltage source DC/AC converter and the duplicate closed-loop feedback control of the DVC is implemented by half-bridge bi-directional voltage source DC/DC converter. The correctness and effectiveness of the topological structure of the DVC and its control strategy are verified by simulation results.更多还原
