Converters for Power Electronics in Variable Speed Pump Storage
The power electronics method serves to regulate variable speed operation within variable speed pump storage systems according to this research. Research focused on reviewing different variable-speed pump storage systems by analyzing both power electronics converters and doubly fed asynchronous machines. The model uses Cyclo-converter and two-level along with three-level voltage source-converter and H-bridge cascaded eleven-level converters as power electronics converters. This analysis evaluates the speed variation together with total harmonic distortion appearing in rotor current of double-fed asynchronous machines for various converter types. The study confirms that the H bridge eleven level converter provides the best available solution. Every simulation model needed the PSIM software for execution.
