Abstract:
In traditional topology of the dynamic voltage restorer(DVR) with flywheel energy storage(FES),a special rectifier is utilized to charge the FES.It increases the complexity and cost of the system.To solve the problem,parallel topology and series topology are proposed.In parallel topology,a switch was involved,which enabled the voltage source converter of the DVR to charge the FES as a rectifier.In series topology,the voltage source converter of the DVR was utilized to charge the FES as a inverter which futher simplified the structure.A new self-charging strategy of the series topology was also proposed and described.Three topologies were assessed and compared with respect to their performance and economy.Experimental results show the validity of the topologies and charging strategies.
